gitStream vs Greptile

gitStream uses YAML configuration files to automate pull request workflows and shape code review. It can add context to pull requests, route work to code experts or reviewers, and merge changes designated as safe, small fixes, or work from trusted teams. Contextual labels can estimate review time and flag Jira information, missing tests, or deleted files. LinearB's AI services can generate pull request descriptions and review code changes. Automations can also notify security teams about sensitive changes. Setup guides cover GitHub, GitHub Server, GitLab, and Bitbucket Cloud; the listed code hosts are GitHub, GitLab, and Bitbucket. gitStream is available on the web or self-hosted. The free account has a monthly cap on pull requests that can trigger automations; once reached, new pull requests do not run them and the check is marked Skipped. Paid pricing starts at $29 per user per month, billed annually. A 45-day Essentials trial requires no credit card but is currently limited to GitHub Cloud users. LinearB says the product uses Git metadata and immediately deletes shallow-cloned data after processing, without scanning, analyzing, or saving code.

Greptile is an AI code review agent for pull requests. It builds a graph of repository functions, classes, and dependencies, then posts findings with suggested fixes in approximately three minutes. Reactions and replies help it adjust: its documentation says it typically stops commenting on unwanted issues after two to three weeks. It supports GitHub, GitLab, Bitbucket, and Cursor Origin, with additional hosted and self-managed providers for enterprise customers. Integrations include GitHub Enterprise, Claude Code, Cursor, Codex, Devin, Jira, and Linear; it can also send issue context to coding agents and offers an MCP connection. The CLI reviews a local feature-branch diff in about 60 seconds and can output suggested fixes in agent mode. Security reviews combine Opengrep rules, software-composition analysis, and AI exploit detection. Greptile offers cloud and self-hosted deployment. Starter is free with 50 credits per month, one active developer, and unlimited repositories. Pro is $30/seat/month; a 14-day trial is listed.
