Best AI agents for reviewing pull requests (2026)

PR Lens

NewcodingOpen source

PR Lens helps people review code that agents wrote. For each pull request it draws animated architecture and data-flow diagrams inside the PR, showing which parts of the app were added, changed or removed, what else depends on the change and how a request now moves through the system. It also flags likely bugs, security holes and design problems in the same review comment, with a ready prompt to hand each fix to your coding agent or an autofix. The open-source core runs locally and installs as an agent skill.

Superlog

Newevals & observabilityOpen source + cloud

Superlog runs AI agents on routine engineering work around production. You set up automations with triggers and connectors, for example rating each new Sentry issue, posting a plain-language summary to Slack and opening a pull request with the fix, comparing error rates and latency against their normal range every hour, adding missing logs and spans to hard-to-debug code paths, or answering community questions from your code and docs. You choose the model and agent harness and bring your own tokens or subscriptions. The core is open source (Apache-2.0) with a hosted version.

OpenComputer

Newagent infraUsage-based

OpenComputer is a platform for building and deploying long-running AI agents as code. You define an agent as a TypeScript function with its model, tools and MCP servers, deploy it with one command, and every session gets its own real cloud computer, with managed sessions, schedules and API keys kept outside the agent's runtime. Templates include a coding agent that edits a repo, runs checks and opens a draft pull request, and market-research and GTM agents; its own Slack coding agent runs on it. Pricing is pay-as-you-go for model calls and per-second machine time.
