What is CodeLazr?
CodeLazr is a browser-based AI coding agent. Sign in with GitHub, pick a repo, and describe a change in plain English. The agent reads your code through the GitHub API, edits as many files as the task needs, and shows every change as a diff. You commit it, open a pull request, or ask for another pass - nothing is cloned to your machine and nothing is pushed without your say-so.
It works with any OpenRouter model, including free ones, so you can code without a subscription. To make cheap and free models dependable, CodeLazr retries failed replies with other models, can have a second model review each diff, and feeds real CI and deploy errors back to the AI for a fix. Think of it as a Claude Code alternative you can use from any browser. Every test run is public on Stats (1,400+ so far) - see how it works and the limitations.
No cloning, no containers
Reads, edits, and commits directly through the GitHub API - nothing touches your machine.
Review before you commit
Every change is staged as a diff you approve, reject, or open as a PR - the AI never pushes blind.
Bring your own model
Pick from OpenRouter models, or plug in your own key to use any model with no budget cap.
Free models. Real results.
Same prompt, sent to every model, no cherry-picking. These built a full SaaS landing site - for pennies.
