How Different Teams Should Choose
High-velocity teams gain from Graphite’s stacked PR workflows but face rising costs and manual fix work. Budget-conscious startups benefit from Gitar’s free tier, which removes tool spend while delivering deeper automation. DevOps-focused organizations rely on Gitar’s self-healing CI to cut failure rates and rerun costs.
Teams concerned about automated commits can start with suggestion mode and add approval workflows. This approach builds trust before enabling auto-commit for specific failure types. Complex CI environments often favor Gitar, since the platform emulates full environments with specific SDK versions and multi-dependency builds. Install Gitar now, automatically fix broken builds, and start shipping higher quality software faster.

Gitar addresses the entire outer loop of development instead of a single workflow slice. The platform turns CI into an intelligent agent system, adds deep analytics for pattern detection, and supports natural language rule creation without YAML complexity. This approach, validated at Pinterest scale with more than 50 million lines of code, positions Gitar as a foundation for next-generation development intelligence rather than a basic code review tool.
Frequently Asked Questions
What Are Stacked Pull Requests?
Stacked pull requests split large features into smaller, dependent branches that build on each other in sequence. Each branch becomes its own PR, which lets reviewers focus on incremental changes instead of massive diffs. This method demands careful dependency management and can add overhead when feedback on lower branches forces rebasing of all dependent PRs. Graphite automates much of this complexity, while Gitar delivers similar workflow speed through automation and healing instead of stacking.
How AI Speeds Up Code Review
AI speeds review by handling analysis, bug detection, and fix generation. Many tools stop at suggestions, which still require manual work and only modest gains. Platforms like Gitar go further by implementing fixes, validating them in CI, and committing working solutions. This model can cut PR cycle times by 30% or more by removing back-and-forth over manual fixes.
Graphite Alternatives for GitLab Teams
GitLab teams need tools with native GitLab support instead of GitHub-only options. Gitar supports both GitLab and GitHub, along with CI systems such as GitLab CI, CircleCI, and Buildkite. This cross-platform coverage prevents lock-in while preserving full automation and healing.
Best Free AI Code Review Option
Gitar offers the most complete free AI code review platform. Teams receive unlimited repositories, users, PR analysis, security scanning, and bug detection without seat limits or credit cards. Other platforms provide narrow free tiers or short trials, while Gitar keeps core review features free and only charges for advanced auto-fix after a 14-day trial.
Whether Graphite Fixes CI Failures Automatically
Graphite does not automatically fix CI failures. It focuses on stacked PR management and AI suggestions. Diamond AI provides context-aware recommendations, but developers still implement fixes manually and must confirm that issues are resolved. Teams remain in a suggestion loop that requires ongoing manual effort.
Pricing Comparison Between Gitar and Graphite
Gitar includes free AI code review, PR summaries, and unlimited usage, with auto-fix features available through a 14-day free trial before paid tiers. Graphite charges $15 to $30 per developer seat for core functionality. A 20-developer team spends $3,600 to $7,200 annually on Graphite, compared with $0 for Gitar’s core features, which simplifies ROI decisions.
ROI From AI Development Platforms
Teams usually see strong productivity gains from AI development platforms. A 20-developer team that spends 1 hour daily on CI and review issues incurs about $1 million in annual productivity costs. Effective platforms can cut this to 15 minutes per day, saving roughly $750,000 each year. Even at half that impact, the ROI supports adoption, especially when core features are free.
