📢 2026-07-14 — Our technical report Agentic Routing: The Harness-Native Data Flywheel is now on arXiv. It shows how the harness-native router turns everyday agent traffic into a self-improving data flywheel, and how multi-model ensemble routing surpasses Fable 5.
OpenSquilla is a token-efficient, microkernel AI agent. A local model router sends each turn to the cheapest model that can handle it, while persistent memory, a layered sandbox, built-in web search, and on-device embeddings round out a single shared turn loop.
Every entry point — Web UI, CLI, and chat channels — runs through that same loop, so tool dispatch, retries, and decision logging behave identically everywhere. A pluggable provider layer speaks to TokenRhythm, OpenRouter, OpenAI, Anthropic, Ollama, DeepSeek, Gemini, Qwen/DashScope, and 20+ other LLM providers with no change to your code or config schema.
OpenSquilla 0.5.8 is the current stable release.

Desktop installers and Quick terminal install give you a prebuilt release —
no Git required. The other two — Install from source and
Develop from source — build from a Git checkout (git clone + Git LFS),
including the Vue control console. Release wheels and Desktop installers already
contain that console, so their users do not need Node.js or npm.
Release install commands use published GitHub release assets. Python wheel installs use versioned wheel filenames because installers validate the version embedded in the wheel filename.
For 0.5.8 desktop use, prefer the packaged desktop installers from
the GitHub Release: OpenSquilla-0.5.8-mac-arm64.dmg on macOS and
OpenSquilla-0.5.8-win-x64.exe on Windows.

The default recommended profile installs SquillaRouter —
OpenSquilla's on-device model router — and its model assets;
OPENSQUILLA_INSTALL_PROFILE=core omits those dependencies. The
separate --router disabled onboarding flag keeps the dependencies
installed but turns the router off at runtime.
On Windows, SquillaRouter's bundled ONNX runtime also needs the Visual
C++ runtime. The from-source PowerShell installer installs it automatically via
winget; the Quick terminal install (uv tool install) path does not — if
startup logs a DLL load failed error, install it manually (see
Troubleshooting). OpenSquilla keeps running with direct
single-model routing until it is installed.
On macOS terminal installs, SquillaRouter's LightGBM runtime may also
need the system OpenMP library. The desktop app bundles the
runtime it needs, but Quick terminal install does not install
Homebrew/system libraries. If startup logs Library not loaded: @rpath/libomp.dylib, run brew install libomp, then restart the
gateway. OpenSquilla keeps running with direct single-model routing
until it is installed.

These fixed links advance only after a newer eligible release passes mirror verification. Use the versioned GitHub Release links above when you need a specific release.
Quit any running OpenSquilla desktop app before upgrading. On macOS, drag the
app from the DMG into Applications for installation or updates, eject the DMG,
then open the Applications copy. The existing Desktop profile in the platform
application-data directory is reused. A terminal installation's
~/.opensquilla is a separate profile; transfer it explicitly from Settings
only if needed.
When upgrading the Windows Desktop from RC3 to RC4 or later, run the new
installer directly over the existing installation. Do not uninstall RC3
first: its uninstaller may remove Desktop user data. Back up
%APPDATA%\OpenSquilla before upgrading. RC4 and later installers preserve
profile data during a normal uninstall.
Code signing policy: docs/code-signing-policy.md.
Note
The 0.5.8 Windows installer is Authenticode signed as Beijing TokenRhythm Technologies Co., Ltd. The published v0.5.4 Windows installer remains unsigned. SmartScreen reputation can still take time to build for a new publisher or application. If enterprise policy blocks the Desktop app, use Quick terminal install instead.
The recommended path on Windows, macOS, and Linux. uv installs
OpenSquilla into its own isolated environment and manages its own
Python — no system Python required. This path installs published
releases only; for main, development branches, or local checkouts
use Install from source.
1. Install uv — skip if uv --version already works.
Linux / macOS:
curl -LsSf https://astral.sh/uv/install.sh | sh
. "$HOME/.local/bin/env"Windows PowerShell:
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"
$env:Path = "$env:USERPROFILE\.local\bin;" + $env:Path2. Install OpenSquilla — the same command on every platform.
uv tool install --python 3.12 "opensquilla[recommended] @ https://github.com/TokenRhythm/opensquilla/releases/download/v0.5.8/opensquilla-0.5.8-py3-none-any.whl"This installs the OpenSquilla wheel from the release URL, then lets
uv download the dependencies declared by the selected extras. The
default recommended extra includes SquillaRouter runtime dependencies
such as ONNX Runtime, LightGBM, NumPy, and tokenizers, so a first install
needs network access unless those wheels are already cached. uv does
not install system native runtimes such as macOS libomp or the Windows
Visual C++ Redistributable; see Troubleshooting if
the router runtime reports a native-library load error.
3. Configure and run.
opensquilla onboard
opensquilla gateway runNote
If opensquilla is not found right after a fresh uv install, open
a new terminal, or re-run the PATH line from step 1.
For a fully pinned install, use the versioned wheel URL:
https://github.com/TokenRhythm/opensquilla/releases/download/v0.5.8/opensquilla-0.5.8-py3-none-any.whl.
Use this path to run OpenSquilla from a checkout without editing it.
The clone is only the package source for the installer; after install,
use the opensquilla command — do not run uv run. Choose
Develop from source instead if you intend to
modify the code.
-
Clone with LFS assets
git lfs install git clone https://github.com/TokenRhythm/opensquilla.git cd opensquilla git lfs pull --include="src/opensquilla/squilla_router/models/**"
-
Run the installer
macOS / Linux
bash scripts/install_source.sh
Windows PowerShell
powershell -ExecutionPolicy Bypass -File ./scripts/install_source.ps1
The script installs
.[recommended](SquillaRouter + memory + local models) into a dedicated user environment viauv tool install. Before the Python install, it runsnpm ciandnpm run buildinopensquilla-webui. Every source reinstall recreates the lockednode_modulestree and rebuilds the console; the first run normally has the largest dependency download, while a warm npm cache reduces later network use but not all build time or disk writes. It then installs the built console with the Python package, falling back topython -m pip install --userwhenuvis unavailable. Ifopensquillais not onPATHafter install (common on a fresh host where~/.local/binis not yet onPATH), runuv tool update-shelland open a new terminal; see Troubleshooting for details.Direct
pip install .,uv tool install ., and VCS URL installs are low-level source-build paths, not substitutes for this installer. A local checkout works only after its Web UI has been built; a VCS URL checkout has no generated artifact and is intentionally rejected. Use this source installer or an official release wheel instead. -
(optional) Install advanced extras. Most channels — Feishu, Telegram, DingTalk, QQ, WeCom, Slack, and Discord — work from the base install. The opt-in extras are:
matrix— Matrix channel (pulls inmatrix-nio)matrix-e2e— Matrix channel with end-to-end encryption (requires libolm)document-extras— PDF generation via WeasyPrint

git lfs installOn Fedora use sudo dnf install -y git git-lfs; on Arch use
sudo pacman -S --needed git git-lfs; install Node.js 22.12+ and npm from
your distribution or nodejs.org, then install uv with the curl command
above. PATH changes from these installers apply to new
terminal sessions.
Installer environment variables and PATH checks
OPENSQUILLA_INSTALL_PROFILE=core bash scripts/install_source.sh # minimal runtime, no SquillaRouter
OPENSQUILLA_INSTALL_DRY_RUN=1 bash scripts/install_source.sh # print the plan onlyVerify which opensquilla your shell runs with command -v opensquilla (macOS/Linux) or where.exe opensquilla (Windows). If it
is not on PATH, run uv tool update-shell. After reinstalling from a
local checkout, restart the gateway so it loads the updated package.
Use this path when you are working on OpenSquilla's source code:
making changes, running tests, or debugging behavior against this
checkout. It is not the normal install path. Unlike
Install from source, this path requires uv:
uv sync creates a repository-local .venv, and uv run executes
commands against the files in this checkout.
cd opensquilla-webui
npm ci
npm run build
cd ..
uv sync --extra recommended --extra dev
uv run opensquilla --helpRun npm run build again after changing Web UI sources. Standard wheel builds
fail closed when the generated console is missing or stale; editable uv sync
installs remain available for backend-only work.
The recommended extra includes SquillaRouter for development too;
the dev extra installs the test, lint, and typecheck tools. Install
additional extras into the same environment you run:
uv sync --extra recommended --extra dev --extra matrix
uv run opensquilla channels status matrix --jsonIn this mode, prefix every opensquilla command in
Configuration with uv run. Do not debug a
development checkout through a user-local opensquilla command — that
command runs in a different Python environment.
Remove OpenSquilla with opensquilla uninstall. It keeps your data by default
and removes only the program:
opensquilla uninstall --dry-run # preview what would be removed and kept
opensquilla uninstall # remove the program, keep your dataTo delete data too, opt in explicitly:
opensquilla uninstall --purge-state # sessions, logs, cache, scheduler, memory
opensquilla uninstall --purge-config # config.toml and secrets (.env)
opensquilla uninstall --purge-all # everything (asks you to type a confirmation)The running gateway is drained and stopped first, deletion stays inside the
OpenSquilla home, and Docker/desktop installs get guided removal steps instead.
Desktop or OS app removal remains platform-specific; the CLI guidance does not
remove a desktop app bundle. See docs/cli.md for the
full reference.
OpenSquilla uses the existing Network reporting switch for V1 statistics and both V2 statistics streams. Reporting is enabled by default and can be turned off in Privacy settings, without separate onboarding choices or consent popups:
- Reliability diagnostics records bounded operation results for app and Gateway startup, crashes, turns, tools, file parsing, updates, and session performance.
- Product and growth analytics records client launches, product activity, and one-time acquisition, onboarding, app-readiness, registration, and first-successful-turn milestones. Existing installations do not become new-user cohorts just by enabling reporting.
The streams retain separate session/journey identifiers, durable queues,
upload endpoints, and retention policies. Reliability events
go to /v1/reliability/events; growth events go to /v1/growth/events.
Retries reuse event_id for server-side deduplication, and growth events are
not sampled.
Application events also carry a one-way, application-specific device_id
derived locally from the OS machine identifier when available. Daily/monthly
activity and feature device counts deduplicate this token across profiles and
client surfaces. Legacy events without it are excluded from device counts;
operation totals and success rates still count actual operations.
V2 statistics never include prompts, responses, file names, file paths, file contents, tool arguments, task parameters, provider configuration, raw account IDs, order data, MAC addresses, IP addresses, or raw OS machine identifiers. Complete crash stacks stay local unless the user explicitly prepares and shares a support bundle.
V1 installation/version reporting at /v1/install and daily conversation/token
totals at /v1/usage run alongside V2 after Gateway readiness. Only completed
UTC days are uploaded; pending days retry hourly. Existing installation state
is retained. Daily event IDs use a persistent random identity per aggregate
database to separate profiles while keeping retries stable. V1 retains its pseudonymous installation
ID derived locally from MAC/IP data, with a persisted random fallback; raw MAC/IP
values are not uploaded. The X-OpenSquilla-Install-Id provider header remains
retired, and V2 keeps its independent identities.
To force all non-user-initiated network observability off before startup:
OPENSQUILLA_PRIVACY_DISABLE_NETWORK_OBSERVABILITY=trueor set:
[privacy]
disable_network_observability = trueThis is a hard veto over V1 and both V2 statistics streams, passive update checks, and
automatic desktop update checks. Disabling Network reporting pauses pending uploads and
stops collection without deleting local statistics state. Previously saved
per-scope declines are migrated to the unified switch being off; users can
then change that one setting. CI, test, and DO_NOT_TRACK environments
also fail closed for statistics uploads. Other user-initiated actions may still contact
configured providers, search services, channels, or release hosts.
Explicit update-availability checks remain disabled while the unified or
legacy update opt-out controls are active.
Legacy opt-out environment variables remain honored:
OPENSQUILLA_TELEMETRY_DISABLED=true
OPENSQUILLA_UPDATE_CHECK_DISABLED=trueThe legacy statistics variable disables V1 and V2 reporting. The legacy update
variable also suppresses V1 uploads for compatibility, but does not disable V2.
See PRIVACY.md for the complete data, reporting, deletion, update,
and external-producer rules.
opensquilla onboard is the interactive first-run wizard. It writes
the active config file and keeps provider secrets in environment
variables when you pass --api-key-env. The router defaults to
recommended (SquillaRouter on supported providers); pass
--router disabled for direct single-model routing.
opensquilla onboard # full interactive wizard
opensquilla onboard --if-needed # idempotent: safe for scripts and re-installs
opensquilla onboard --minimal # provider only; skip channels and search
opensquilla onboard status # inspect every setup section without writingIn SSH, CI, or any environment without a TTY, use the non-interactive form — keep the secret in the environment and pass its name, not its value:
Linux / macOS
export OPENROUTER_API_KEY="sk-..."
opensquilla onboard --provider openrouter --api-key-env OPENROUTER_API_KEYWindows PowerShell
$env:OPENROUTER_API_KEY="sk-..."
opensquilla onboard --provider openrouter --api-key-env OPENROUTER_API_KEYOpenRouter is only an example — substitute any supported provider and its API-key variable.
Re-configure one section later without redoing the whole wizard (these examples assume the relevant API key is already in the environment):
opensquilla configure provider --provider openai --model gpt-4o --api-key-env OPENAI_API_KEY
opensquilla configure router --router recommended
opensquilla configure search --search-provider duckduckgo
opensquilla configure search --search-provider exa --api-key-env EXA_API_KEY
opensquilla configure channelsSections: provider, router, channels, search,
image-generation, memory-embedding. The Web UI exposes the same
catalog and status model at /control/setup: Provider and Router are
the fast path, while Channels, Search, Image generation, and Memory
embedding sit in the Capability Center and can be configured later.
Empty channels are treated as an opt-out, not a failed setup.
Config load order: OPENSQUILLA_GATEWAY_CONFIG_PATH →
./opensquilla.toml → ~/.opensquilla/config.toml → built-in
defaults. Environment values for individual secrets always win over
file values.
If you already have state under ~/.openclaw or ~/.hermes, run a
dry run first to inspect the migration report, then apply it explicitly:
opensquilla migrate openclaw --json
opensquilla migrate openclaw --apply
opensquilla migrate hermes --json
opensquilla migrate hermes --applyUse opensquilla migrate --source openclaw,hermes --apply to import
both default homes. Add --migrate-secrets only after reviewing the dry-run
report. See MIGRATION.md for custom paths and conflict
handling.
opensquilla gateway run # foreground, 127.0.0.1:18791
opensquilla gateway start --json # background + health wait
opensquilla chat # interactive REPL
opensquilla agent -m "your prompt" # one-shot, automation-friendlyFor subprocess progress, add --event-stream-stderr. The final result keeps
its existing stdout format, while stderr receives incrementally flushed,
privacy-bounded v1 JSONL events. Consumers must drain stderr continuously and
only treat objects with "_event": true as events because ordinary diagnostics
can share the stream. See docs/cli.md
for the versioned schema and compatibility contract.
Parallel agent subprocesses must use separate profile homes and persistent state roots. Set both variables for every child:
OPENSQUILLA_STATE_DIR=/tmp/agent-a \
OPENSQUILLA_GATEWAY_STATE_DIR=/tmp/agent-a/state \
opensquilla agent -m "task A" --json --event-stream-stderr &
OPENSQUILLA_STATE_DIR=/tmp/agent-b \
OPENSQUILLA_GATEWAY_STATE_DIR=/tmp/agent-b/state \
opensquilla agent -m "task B" --json --event-stream-stderr &
waitOn Windows, set both values in each child process environment. If an
orchestrator copies config.toml or .env, remove or rewrite every state_dir
or OPENSQUILLA_GATEWAY_STATE_DIR value as well. Explicitly shared session DB,
workspace, scratch, transcript, and usage paths remain shared by design.
Development-only OpenTUI terminal UI. Release installs continue to use the Python-native chat. The richer full-screen frontend currently runs only from a Develop from source checkout; no companion host is published in release assets or installed by the release installer. From the checkout, install the pinned Bun dependencies once, then launch against that same source tree:
bun install --frozen-lockfile --cwd=src/opensquilla/cli/tui/opentui/package OPENSQUILLA_TUI_DEV_SOURCE_HOST=1 uv run opensquilla chat --ui tuiUse
opensquilla chat --ui plainto require the stable renderer. See docs/tui.md for terminal chat usage and docs/features/tui-frontend.md for backend details.
Open the Web UI at http://127.0.0.1:18791/control/. The Health view shows whether OpenSquilla is ready, what is not ready, and the next recovery steps. From the CLI, run:
opensquilla doctor
opensquilla doctor --json
opensquilla doctor --config ./opensquilla.toml --json/health and /healthz are lightweight liveness endpoints for process
checks. opensquilla doctor and the Web UI Health view are the readiness
surfaces for provider config, memory, logs, search, channels, sandbox
posture, router, image generation, and recovery guidance. Press
Ctrl+C to stop a foreground gateway.
Other command groups include sessions, skills, memory, migrate,
cron, channels, providers, models, and cost. Run
opensquilla --help or opensquilla <group> --help for details.
Advanced configuration — verify a channel, public network binding, Docker
Connect and verify a messaging channel
Channel saves are config changes, not runtime-connectivity proof. Restart the gateway after channel edits, then verify the live channel:
opensquilla gateway restart
opensquilla channels status <name> --jsonTreat a channel as connected only when the status payload reports
enabled=true, configured=true, and connected=true. Feishu
defaults to websocket mode, Telegram to polling, and Slack can use
Socket Mode — none of those modes needs a public URL. Feishu webhook
mode, Telegram webhook mode, Slack webhook mode, and WeCom require a
public, provider-reachable URL.
Public network binding
To reach the Web UI from another machine, bind the gateway to all interfaces and use the host's public IP:
