## Summary

Trunk unifies parallel linting via Trunk Check, CI test analytics, and merge queue orchestration, giving engineering teams a single quality gate across all languages and frameworks.

## Company Overview

Trunk is a San Francisco-based developer platform company that provides tools for code quality enforcement, CI test management, and merge queue orchestration to help engineering teams ship code faster with fewer quality regressions. Trunk Check runs dozens of linters and code analyzers in parallel during local development and CI, providing a single consistent quality gate that is easy to configure and maintain across different languages and frameworks. Trunk CI Analytics tracks CI pipeline performance and test flakiness over time, helping engineering teams identify and fix slow or unreliable tests that are blocking developer velocity. Trunk Merge provides an intelligent merge queue that manages concurrent pull request merges, preventing broken mainline builds by testing combinations of PRs together before merging. Founded in 2021 and backed by investors including Andreessen Horowitz and Tiger Global, Trunk has grown as engineering organizations seek to standardize quality practices and reduce CI bottlenecks that slow development cycles.

## Frequently Asked Questions

### What does Trunk's merge queue do?
Trunk's merge queue manages concurrent pull request merges by batching and testing combinations of PRs together before merging to mainline, preventing scenarios where individually green PRs break the main branch when merged together.

### What is Trunk?
Trunk is a developer platform providing code quality enforcement (Trunk Check), CI test analytics (Trunk CI Analytics), and merge queue orchestration (Trunk Merge) to help engineering teams ship faster with fewer quality regressions and broken builds.

### What is Trunk Check?
Trunk Check is a code quality tool that runs dozens of linters and static analysis tools in parallel during local development and CI, providing a single consistent quality gate across all languages and frameworks in a repository without requiring per-tool configuration for each linter.

### How does Trunk CI Analytics help with test flakiness?
Trunk CI Analytics tracks CI pipeline performance and individual test stability over time, identifying tests that pass inconsistently (flaky tests) and measuring their impact on build times. Teams use this data to quarantine unreliable tests and prioritize reliability improvements that unblock developer velocity.

### Does Trunk integrate with GitHub?
Yes. Trunk integrates with GitHub through GitHub Actions and GitHub Apps, posting code quality check results as pull request annotations, managing merge queue operations through the GitHub PR interface, and surfacing CI analytics in a connected dashboard.

### What linters does Trunk Check support?
Trunk Check supports over 100 linters and formatters including ESLint, Prettier, Black, Flake8, Clippy, golangci-lint, ShellCheck, Terraform validators, and many others, running all applicable checks in parallel and caching results for unchanged files.

### How does Trunk's merge queue improve on GitHub's native merge queue?
Trunk Merge provides more sophisticated batching strategies, configurable merge prioritization, parallel branch testing, and detailed analytics about queue throughput and merge failures compared to GitHub's native merge queue — giving engineering managers better insight into release pipeline health.

### Is Trunk suitable for monorepos?
Yes. Trunk is particularly well-suited to monorepos with multiple languages and tooling ecosystems, where managing dozens of separate linters and ensuring consistent quality enforcement across all packages is otherwise a significant maintenance burden.
