Closes #309. Three root-cause fixes in `frontend/src-tauri/src/lib.rs`: 1. **Background stderr drainer.** `jarvis serve` was spawned with `stderr(Stdio::piped())` but its 4 KB Windows pipe buffer would fill from the startup log volume before the child could bind its HTTP port — hanging the process mid-startup. Now a tokio task drains stderr from the moment of spawn into a rolling 16 KB tail buffer; the pipe never fills. 2. **`try_wait()` early-exit detection.** The old `wait_for_url` was blind to child crashes — uv-not-on-PATH or extension-import failures would silently waste the full 10-minute timeout. The new `wait_for_jarvis_health` checks the child's exit status each iteration and surfaces the stderr tail with the exit code. 3. **HTTP 503 distinguished from connection-refused.** A 503 means the server bound but the inference engine failed to load (terminal); we now surface the body text immediately rather than polling for 10 minutes. Adversarially reviewed before commit — caught and fixed a stderr-pipe back-pressure regression on the Ready path before push. Huge thanks to @xoomarx for the careful #309 repro — without that exact symptom signature ("stuck on Starting api server" on Windows) the pipe-buffer deadlock would have been very hard to identify from the user-visible behavior alone.

Personal AI, On Personal Devices.
Why OpenJarvis?
Personal AI agents are exploding in popularity, but nearly all of them still route intelligence through cloud APIs. Your "personal" AI continues to depend on someone else's server. At the same time, our Intelligence Per Watt research showed that local language models already handle 88.7% of single-turn chat and reasoning queries, with intelligence efficiency improving 5.3× from 2023 to 2025. The models and hardware are increasingly ready. What has been missing is the software stack to make local-first personal AI practical.
OpenJarvis is that stack. It is a framework for local-first personal AI, built around three core ideas: shared primitives for building on-device agents; evaluations that treat energy, FLOPs, latency, and dollar cost as first-class constraints alongside accuracy; and a learning loop that improves models using local trace data. The goal is simple: make it possible to build personal AI agents that run locally by default, calling the cloud only when truly necessary. OpenJarvis aims to be both a research platform and a production foundation for local AI, in the spirit of PyTorch.
Installation
macOS / Linux:
curl -fsSL https://open-jarvis.github.io/OpenJarvis/install.sh | bash
The installer handles everything for you — including uv, the Python venv, Ollama, and a small starter model. You don't need to install anything first.
Windows: the installer is a bash script and won't run in PowerShell or cmd. Pick one of:
- WSL2 (recommended for the CLI / Python SDK) — one-time setup in an admin PowerShell, then run the same
curl … | bashinside Ubuntu:Open the Ubuntu shell that gets installed, then follow WSL2 install instructions.wsl --install -d Ubuntu-24.04 - Desktop app — download the Windows installer (
.exe) from the latest desktop release (macOS.dmgand Linux.deb/.rpm/.AppImageare there too) for the GUI experience, no terminal required. Prerequisite: the desktop app expects uv to be installed already — if it isn't, install it first in PowerShell, then launch the app:powershell -ExecutionPolicy Bypass -c "irm https://astral.sh/uv/install.ps1 | iex"
About 3 minutes on a typical broadband connection. Then:
jarvis
The Rust extension and bigger models continue downloading in the background while you chat. Run jarvis doctor to see status.
Platforms: macOS (Intel + Apple Silicon), Linux, WSL2 on Windows. Native Windows is not supported — use WSL2 or the desktop binary.
Manual install / contributors: see docs/getting-started/install.md.
Quick Start
curl -fsSL https://open-jarvis.github.io/OpenJarvis/install.sh | bash
jarvis
jarvis init --preset <name> switches to a starter config. Available presets: morning-digest-mac, morning-digest-linux, morning-digest-minimal, deep-research, code-assistant, scheduled-monitor, chat-simple.
Starter Configs
Install any preset with one command:
uv run jarvis init --preset morning-digest-mac # or any preset below
Prefix every
jarvis ...invocation withuv run, or activate the venv first (source .venv/bin/activate) so plainjarvis ...works for the rest of your shell session.
| Preset | Use Case | What it does |
|---|---|---|
morning-digest-mac |
Daily Briefing (Mac) | Spoken briefing from email, calendar, health, news with Jarvis voice |
morning-digest-linux |
Daily Briefing (Linux) | Same, with vLLM support for GPU servers |
morning-digest-minimal |
Daily Briefing (minimal) | Just Gmail + Calendar, runs on any machine |
deep-research |
Research Assistant | Multi-hop research across indexed docs with citations |
code-assistant |
Code Companion | Agent with code execution, file I/O, and shell access |
scheduled-monitor |
Persistent Monitor | Stateful agent that runs on a schedule with memory |
chat-simple |
Simple Chat | Lightweight conversation, no tools needed |
# Example: Morning Digest on Mac
uv run jarvis init --preset morning-digest-mac
uv run jarvis connect gdrive # one OAuth flow covers Gmail, Calendar, Tasks
uv run jarvis digest --fresh # generate and play your first briefing
# Example: Deep Research
uv run jarvis init --preset deep-research
uv run jarvis memory index ./docs/ # requires the Rust extension — see Setup above
uv run jarvis ask "Summarize all emails about Project X"
Skills
Skills teach agents how to better use tools and improve their reasoning. Every skill is a tool — agents discover them from a catalog and invoke them on demand.
# Install skills from public sources
jarvis skill install hermes:arxiv
jarvis skill sync hermes --category research
# Use skills with any agent
jarvis ask "Use the code-explainer skill to explain this Python code: for i in range(5): print(i*2)"
# Optimize skills from your trace history
jarvis optimize skills --policy dspy
# Benchmark the impact
jarvis bench skills --max-samples 5 --seeds 42
Import from Hermes Agent (~150 skills), OpenClaw (~13,700 community skills), or any GitHub repo. Skills follow the agentskills.io open standard.
See the Skills User Guide and Skills Tutorial for details.
Built-in Agents
OpenJarvis ships with eight built-in agents across three execution modes (on-demand, scheduled, continuous):
| Agent | Type | What it does |
|---|---|---|
morning_digest |
Scheduled | Daily briefing from email, calendar, health, news — with TTS audio |
deep_research |
On-demand | Multi-hop research with citations across web and local docs |
monitor_operative |
Continuous | Long-horizon monitoring with memory, compression, and retrieval |
orchestrator |
On-demand | Multi-turn reasoning with automatic tool selection |
native_react |
On-demand | ReAct (Thought-Action-Observation) loop agent |
operative |
Continuous | Persistent autonomous agent with state management |
native_openhands |
On-demand | CodeAct — generates and executes Python code |
simple |
On-demand | Single-turn chat, no tools |
See the User Guide and Tutorials for detailed setup instructions.
