DeepSource vs Graphite: Features, Pricing and User Reviews 2026

DeepSource is a platform that reviews your code and helps you fix problems before they cause trouble. It checks every pull request against thousands of rules, then uses an AI agent to catch things that plain rules might miss.

Along with reviewing code, it looks for security bugs, exposed secrets, risky dependencies, and missing test coverage. When it finds a problem, it can suggest or even apply a fix automatically through a feature called Autofix.

DeepSource works with GitHub, GitLab, Bitbucket, and Azure DevOps, and connects to tools like Slack and Jira. It also has an MCP server so AI coding tools such as Claude Code and Cursor can read its reports and fix issues on their own.

There is a free plan for open source projects, a Team plan for paid usage, and a custom Enterprise plan with self hosted options for larger companies.

Graphite is a code review and pull request tool built for teams that use GitHub. Instead of pushing one large change at a time, developers can break work into small, connected pull requests called a stack, so each piece is easier to review and merge.

The platform adds an AI reviewer that checks every pull request for bugs, security issues, and style problems, and suggests fixes that can be applied with one click. There is also an AI chat built into the pull request page that can answer questions about the code and help fix failing tests.

Teams also get a merge queue that lands changes in the right order while keeping the main branch stable, along with an inbox, insights, and integrations with Slack and Linear.

Graphite works through a command line tool, a VS Code extension, and a web app, and it stays in sync with GitHub at all times.
