Save money

Bring your own subscription or key.

Most bug bots charge you directly for inference. Instead, just connect your Claude or ChatGPT subscription, or add an Anthropic or OpenAI API key, and pay your provider directly. You only pay us for the time your sessions use.

Stay on the frontier

Choose the best agent, model, and effort.

Most bug bots select the model for you. You can decide which frontier model to run reviews with.

When Anthropic or OpenAI ship a stronger model, you can start to use it right away.

Also leverage the amazing work that goes into Claude and Codex by using their agents to conduct reviews.

Sharpen your reviews

Run multiple reviews simultaneously.

Run targeted reviews with specialized prompts for things like security.

Each review reports its own GitHub check, so branch protection can require the ones that matter.

Test reviews with a new model or new instructions next to your current setup and compare the results side-by-side on real pull requests.

Stay focused

Fix bugs without dropping what you're doing.

Spot a problem in the review, start a fix right from the comment, and get back to what you were doing. A coding session picks up every open finding.

It keeps going until the review passes. Tough Crowd re-reviews each push, and the session fixes whatever's left, back and forth until it's done.

You come back to a pull request that's safe to merge.
