Reviewer
Tools for conversation based development.
Reviewer reviews what the agent wrote, runs it on your machine, and keeps the conversation on the line it belongs to.
View on GitHubFree and open source.
Runs on your own machine, against your own repository.
Comment on any line of any file, and the next agent reads it.
Hand the review to whichever agent you already run.
Start the services and keep their logs beside the diff.
Say it on the line it belongs to
Comment on your local changes, a single commit, a range of them, or a GitHub pull request. Comments are stored with the code, so the next agent to open the repository reads exactly what you wrote, against the lines you wrote it about.
Hand it to the agent you already run
Claude Code, Codex, opencode, Cursor, or a plain shell. Reviewer builds the command, drops the prompt in, and streams back whatever the tool prints. Point it at your own CLI with a {prompt} token and it behaves like the built-in ones.
Run it and look at it
Named run configurations start your services from inside the app and keep their logs beside the diff, so the change and what it does at runtime are read in one window.
The whole repository, not only the diff
Browse files, stage and commit, page through history, and open a pull request without leaving the review. Several repository roots can sit in one window when a project spans more than one.
Threads
Reply on a comment and resolve it, with the file tree marking every file still carrying one.
History
Page through the project graph with its branch refs, and review any commit or range of them.
Pull requests
Open a pull request, review one from GitHub, and resolve conflicts without leaving the window.
Multi-repo
Several repository roots sit in one window when a project spans more than a single checkout.
Terminals
Terminal sessions as tabs, per branch, beside the code they were opened against.
Keyboard
A command palette on ⌘K reaches every file, branch and action in the project.
Local
Your repository never leaves the machine — Reviewer runs the agents you have already installed.
Open source
Read the source, file an issue, or build it yourself from the repository.
