// how it works
How it works
- Install it
Editor extensions, terminal commands, or standalone apps — most install in under a minute.
- Point it at a model
Use a hosted frontier API, or keep everything local with an open model backend.
- Open your repo
The tool indexes your codebase so suggestions and edits are project-aware.
- Code together
Ask for features, let it edit files, run tests, and review diffs before you accept.
// features
Why people love it
Agentic editing
Not just autocomplete — plans, edits multiple files, and runs commands.
Codebase awareness
Indexes your repo so answers respect your actual code, not guesses.
Terminal & IDE
Lives where you work: VS Code, JetBrains, Neovim, or the plain terminal.
Model flexibility
Swap between frontier APIs and local models per task.
Diff-first workflow
Every change is a reviewable diff — you stay in control.
Open & hackable
Customize prompts, tools, and behavior; no black box.

// run it
Run it yourself
- Step 1 — Clone the repo
Download the source and move into the project folder.
git clone https://github.com/anomalyco/opencode.git cd opencode - Step 2 — Install dependencies
Use the package manager the project specifies (check for pnpm or yarn lockfiles).
npm install - Step 3 — Start it
Launch the dev server or build, per the README.
npm run dev
// use cases
What you can build
- Ship features faster with an AI pair programmer.
- Refactor legacy code with confidence.
- Onboard onto unfamiliar codebases.
- Automate tests, docs, and chores.
Two smaller dev tools solve the day-to-day friction around coding agents: Arc Kit is an AI-driven enterprise architecture governance harness spanning strategy, delivery and assurance, and Codmate is a macOS app for browsing, resuming and reviewing your AI coding sessions. The Dev Tools shelf also holds @shadcn/lint — an agent-first linter for Tailwind design systems: you define what is allowed, and errors explain the fix in terms of your components.

// faq
Questions, answered
Will it replace developers?
It multiplies them — the best results come from developers directing, reviewing, and owning the design.
Local or cloud models?
Cloud frontier models code best today; local models keep everything private and free.
Who maintains OpenCode?
It is an open-source project at anomalyco/opencode with 28,116 forks. Check the repo's contributors and recent commits to see how active maintenance is.
Is my code sent anywhere?
With local models, no. With APIs, check the provider — many offer zero-retention modes.
Which editor does it support?
Coverage varies: VS Code and terminal are universal; check each tool for JetBrains/Neovim.
Is it free?
The tools are open-source; model usage may cost if you use paid APIs.
