One agent for the open web
Checkout, a job application, a multi-step wizard, reading one page to write on another — no integration, no scripts.

OpenSidebar is an open-source Chrome extension that puts an autonomous agent in your side panel — describe a task in plain English and it sees the page, clicks, types, and carries multi-step work across tabs to done.
Bring your own API key. No subscription, no telemetry, no backend — everything runs in your browser.
Quick start
Two minutes to your first task
The Chrome Web Store listing is on the way. Until then, load the unpacked build — it takes one clone and one command.
Chrome Web Store
One-click install
A signed listing so anyone can add OpenSidebar straight from Chrome.
Coming soonFrom source
Load the unpacked build
# clone & build git clone https://github.com/krisshkodrani/OpenSidebar cd OpenSidebar corepack enable corepack pnpm install corepack pnpm run dist # then in Chrome chrome://extensions → Developer mode → Load unpacked → select dist/
Requires Node.js 22+ and a supported provider API key.
Recorded live
See it actually do the work
No mockups, no cherry-picked frames — these are real sessions the agent drove end to end.
Operates enterprise apps, live
The same agent drives ServiceNow — creating incidents, ordering from the catalog, filtering lists. One agent, every workflow.
Watch Mode keeps an eye out
Leave it watching a page and it tells you the moment something changes — flagged “back in stock” the instant it flipped.
Your provider, your models
Paste a key, pick your models, go. Fireworks, OpenRouter, Moonshot, or Xiaomi — nothing hardcoded.
Watch the full tour
Eleven scenes in three acts — the open web, staying in control, and the ServiceNow finale. Narrated, 3:35.
Recorded live — no scripts, no post-editing. Executor: Kimi K2.7 Code (vision) · Planner: GLM 5.2 · Fireworks AI
What it does
An agent that sees, plans, acts — and stays in your control
Sees the page like you do
A vision model works from the live screenshot and DOM — reads charts, zooms into fine print, and handles pages that defeat text-only bots.
51 browser tools
Clicking, typing, scrolling — plus file upload and download, tab and window management, and structured table, chart, and filter extraction.
Safe by default
Four approval modes. Consequential actions pause for you, and form submits are dry-run first — you approve the exact field values before they’re sent.
Plans, executes, verifies
A planner decomposes the task, an executor drives it, a verifier confirms the result — and stuck runs escalate to a stronger model instead of burning turns.
Remembers what matters
A local profile you review yourself, per-site skills learned from successful runs, and checkpoints that survive restarts. Sensitive fields are consent-gated and encrypted.
Watch Mode
Leave it watching a page and it tells you the moment the page changes — a price, a status, a new listing.
Speak or type
Voice input transcribes straight into the composer — describe the task out loud and let it run.
Yours to inspect
Every session produces a full-fidelity local trace. Keys live in Chrome storage; traffic goes browser → provider and nowhere else.
Bring your own key
Your provider. Your models. Your data.

Your API key stays in Chrome storage; page context goes only to the provider you configure. No analytics, no tracking, no hosted relay, no OpenSidebar servers.
In the open-source repo · developer builds
Trust, but verify — locally.
The repo ships a full observability workspace: replay any run as a story — plan, nodes, turns, and the verifier's judge model showing its per-criterion reasoning and cost — then record whether the outcome was actually right. Traces never leave your machine.
