# Trunk

> CI reliability platform that helps engineering teams detect flaky tests, accelerate merges, and keep CI green. Founded in 2021. SOC 2 Type II certified.

- Last updated: 2026-03-12
- Full version: https://trunk.io/llms-full.txt

Trunk eliminates two critical bottlenecks in software development: flaky tests that erode CI reliability, and merge conflicts that slow down code delivery. The platform serves DevEx, DevOps, and engineering teams at companies like Brex, Faire, Metabase, Zillow, and CockroachDB.

## Docs
- [Full Documentation](https://docs.trunk.io/llms.txt): Complete platform documentation covering Merge Queue, Flaky Tests, setup, administration, and API references

## Core Products
- [Flaky Tests](https://trunk.io/flaky-tests): Automatically detect, quarantine, and eliminate flaky tests across any language, test runner, and CI provider. Features AI-powered failure analysis, auto-quarantine during CI runs, ticketing integrations (Jira, Linear), PR comments, Slack alerts, and webhooks.
- [Merge Queue](https://trunk.io/merge-queue): Enterprise merge queue with anti-flake protection, intelligent batching (up to 100 PRs), parallel queue lanes, auto-bisection on failure, predictive testing, priority merging, and stacked PR support. Tests every PR against latest main.

## Pricing
- [Pricing](https://trunk.io/pricing): Free tier (up to 5 committers, 5M test spans/month), Team tier (unlimited committers, merge queue, multi-CI support), Enterprise tier (SAML, on-premise, volume discounts, custom integrations)

## Integrations

### Merge Queue Build Systems
- [Merge Queue + Bazel](https://trunk.io/merge-queue/trunk-merge-and-bazel): Dynamic parallel queues powered by Bazel dependency graph
- [Merge Queue + Nx](https://trunk.io/merge-queue/trunk-merge-and-nx): Dynamic parallel queues powered by Nx project graph

## Comparisons

- [Trunk vs GitHub Merge Queue](https://trunk.io/trunk-vs-github-merge-queue): Trunk's parallel lanes architecture validates independent changes concurrently instead of GitHub's single FIFO queue, enabling faster merges at scale.
- [Trunk vs Mergify](https://trunk.io/trunk-vs-mergify): Trunk offers dynamic parallel queues, optimistic merging, pending failure depth, and flaky test protection—all absent from Mergify.
- [Trunk vs BrowserStack](https://trunk.io/compare/trunk-vs-browserstack): Trunk specializes in flaky test detection and management in CI/CD pipelines, while BrowserStack focuses on cross-browser and cross-device testing compatibility.
- [Trunk vs CircleCI](https://trunk.io/compare/trunk-vs-circleci): Trunk provides CI-agnostic flaky test management with quarantining and ticketing, whereas CircleCI's test insights are limited to its own ecosystem.
- [Trunk vs Launchable](https://trunk.io/compare/trunk-vs-launchable): Trunk's standout advantage is automatic test quarantining that isolates flaky tests from blocking CI, a capability Launchable lacks.
- [Trunk vs LambdaTest](https://trunk.io/compare/trunk-vs-lambdatest): Trunk specializes in flaky test management with deep developer workflow integration (PR comments, Jira ticketing), while LambdaTest is a broader cross-browser testing platform.
- [Trunk vs Gradle](https://trunk.io/compare/trunk-vs-gradle): Trunk offers platform-agnostic flaky test detection across multiple CI systems and frameworks, while Gradle Develocity focuses primarily on the Gradle ecosystem.
- [Trunk vs Rainforest QA](https://trunk.io/compare/trunk-vs-rainforest-qa): Trunk automates flaky test detection within existing CI/CD pipelines, while Rainforest QA focuses on no-code test creation with a retry-based approach.
- [Trunk vs Codecov](https://trunk.io/compare/trunk-vs-codecov): Trunk actively manages flaky tests through quarantining and ticketing, while Codecov focuses on code coverage analytics with only basic flaky test detection.
- [Trunk vs Testmo](https://trunk.io/compare/trunk-vs-testmo): Trunk automates flaky test detection and quarantining in CI/CD, while Testmo is a broader test management platform without specialized flake remediation.
- [Trunk vs Testim](https://trunk.io/compare/trunk-vs-testim): Trunk is laser-focused on flaky test detection with deep analytics and framework-agnostic support, while Testim is a test automation platform with flake handling as a secondary feature.
- [Trunk vs SauceLabs](https://trunk.io/compare/trunk-vs-saucelabs): Trunk specializes in automated flaky test detection and quarantining to prevent CI disruptions, while SauceLabs offers a broader testing platform with manual debugging tools.
- [Trunk vs Testomatio](https://trunk.io/compare/trunk-vs-testomatio): Trunk's automated test quarantining prevents flaky tests from blocking CI pipelines, while Testomatio focuses on broader test management with identification and reporting.
- [Trunk vs Buildkite](https://trunk.io/compare/trunk-vs-buildkite): Trunk is CI-provider agnostic for flaky test management across diverse environments, while Buildkite restricts its test analytics to its own platform.
- [Trunk vs Qase](https://trunk.io/compare/trunk-vs-qase): Trunk's automated detection and quarantining contrasts with Qase's manual, reactive approach to flaky test management.
- [Trunk vs BuildPulse](https://trunk.io/compare/trunk-vs-buildpulse): Trunk offers a more comprehensive platform with integrated ticketing, failure analysis, webhooks, and free open-source pricing, while BuildPulse focuses on basic flaky test detection.
