OpenClaw 2026.9.4: the open-source personal agent that grabs your to-do list

It started as a weekend project called Clawdbot, became one of the most-starred agent repos on GitHub, and now ships dated versions almost weekly. Version 2026.9.4 landed September 10 — here's what it is and what's new.

OpenClaw is an open-source personal AI assistant: software you run yourself that handles mail, messages, reminders, issues, bookmarks, voice calls, and vault secrets on your behalf. It began in late November 2025 as Clawdbot, was renamed twice in January 2026 (Moltbot, then OpenClaw), and grew into one of the fastest-starred projects in GitHub history — the project's own site quotes Y Combinator calling it the most-starred software repo on GitHub within five months. Creator Peter Steinberger now works at OpenAI, but OpenClaw is stewarded by the independent OpenClaw Foundation, a US non-profit that signs every release and keeps the whole product MIT licensed.

What it does for you

Think of it as a chief-of-staff daemon rather than a chat window. You install a gateway on a Mac, PC, Linux box, or server, connect your chat apps, and the agent works in the background: checking mail, reading messages, ordering things, sending reminders, filing GitHub issues, and handling voice calls. Setup runs through a guided onboard (openclaw onboard), with full desktop apps for macOS, Windows, and Linux that install everything — gateway, chat, and setup — for you.

What's new in 2026.9.4 (September 10, 2026)

• Rollback-safe updates: failed updates now retain the previous package and restore it with its configuration when schema and config checks prove rollback is safe. Database migrations still need a verified pre-update backup.
• Plugins in one place: bundled and ClawHub plugins can be discovered, installed, and managed — setup, settings, access — from a unified Plugins workspace in the Control UI.
• Prepared cloud sessions: start eligible Linux sessions from prepared local projects or public GitHub repositories, and build reusable snapshots before starting a conversation.
• Terminal Q&A: keyboard-driven choices, free-text answers, and multi-question prompts in both gateway-connected and local sessions.
• GPT Image 2.5: new Flare and Sunburst image variants selectable through OpenAI or fal without changing your default model.

What 2026.9.3 fixed first (the maturity release)

The previous release — 1,844 pull requests from 190 contributors — was about dependability: updates that recover cleanly, faster session reconnects, live browser-automation viewing, revocable chat share links, searchable meeting transcripts, repository-backed cloud work, per-agent Skill Workshop grouping, native Mac browser tabs, and per-account model controls. Read 2026.9.4 as the release that made 2026.9.3's foundations safe to upgrade to.

Installing it

• One-liner (macOS/Linux): the install script, then openclaw onboard to meet your lobster.
• npm: a global install for Node users.
• Desktop apps: macOS 15+ universal build at v2026.9.4; Windows and Linux companions on their own tracks.
• Updates: switch between stable and dev channels with the update command when you want fresher builds.

By default an install sends the Foundation nothing but a daily version check — which you can turn off.

Honest limits

Speed is OpenClaw's virtue and its tax. The same cadence that ships features weekly has previously shipped breaking changes (six in one March release), so "always latest" is a policy for a staging box, not a production one. And like any agent with hands on your mail and messages, its power scales with the care you put into credentials, approvals, and sandboxing.
