About

CodeLazr is a web-based AI coding agent that edits your GitHub repos directly from the browser. No install, no cloning, no containers. Pick any OpenRouter model, including free ones, or bring your own API key. Every change is staged as a diff you review before it commits, auto-commits, or opens a pull request. CodeLazr is built to make cheap and free AI models reliable for real coding: automatic retries with a fallback chain of models, a second model that reviews each diff before commit, and detectors for the common ways weaker models fail. Includes built-in prompt templates for common tasks like fixing bugs, writing tests, refactoring, and writing docs. More than 1,400 test runs are published publicly on the CodeLazr stats page, failures included. Free plan with free models and no card required, Pro at $10 per month, or bring your own key to use it free forever.

About

fx is a tiny, open, native coding agent harness and CLI written in Zig, optimized for research, performance, and embeddability as part of larger systems. Its design focuses on minimalism across the system prompt, tools, feature set, memory use, and a 6 MB binary, with an interface intended to feel closer to a Unix shell than a heavy terminal IDE. fx cold starts in microseconds and performs no unnecessary work or I/O before accepting input, making it suitable for programmatic use, resource-constrained environments, and agent sandboxes. Developers can start it inside a project and ask it to read files, search code, run commands, make changes, execute tests, and stream tool calls as they happen. The core is model- and provider-agnostic, supporting local models, gateways, direct provider access, and cloud inference. It is context-efficient by design, using a minimal system prompt and toolset to reduce token overhead and improve time to first token.
