# BuildPulse > BuildPulse is a CI analytics platform for engineering teams shipping on GitHub Actions. We provide faster, cheaper runners; automatic flaky test detection; code coverage; CI and test health metrics; and AI code review. BuildPulse helps engineering teams ship faster by combining performance optimization (runners that finish jobs twice as fast at less than half the cost of GitHub-hosted runners), test reliability (automatic flaky test detection, quarantine, and Jira-linked triage), code quality signal (coverage trends per branch and per file), and engineering visibility (pass rate, build duration, and flaky-test disruption from your existing CI data), all in one platform. The audience is engineering leaders and senior ICs at fast-moving software teams. BuildPulse is free to start; usage-based pricing as you grow; enterprise plans available. ## Products - [BuildPulse Runners](https://buildpulse.io/products/runners): faster GitHub Actions runners at less than half the cost, measured and published. Drop-in replacement. - [CircleCI and Semaphore runners](https://buildpulse.io/docs/runners/circleci-semaphore): run CircleCI jobs (self-hosted machine runner) and Semaphore jobs (self-hosted agent) on the same BuildPulse machines and per-minute prices. Setup and prices next to CircleCI and Semaphore cloud machines. Each job gets a fresh machine, usually running in under a minute. - [Flaky Test Detection](https://buildpulse.io/products/flaky-tests): Automatic detection across every PR and branch. Quarantine, trend tracking, Jira-linked triage. - [Code Coverage](https://buildpulse.io/products/code-coverage): Coverage trends per branch and per file, with native LCOV and Cobertura XML support. - [Engineering Metrics](https://buildpulse.io/products/engineering-metrics): Pass rate, build duration, and flaky-test disruption from existing CI data. - [AI Code Review](https://buildpulse.io/products/ai-features): AI reviews on your pull requests, running on frontier models, opt-in per repository. ## Use BuildPulse from AI assistants (MCP) BuildPulse ships a Model Context Protocol (MCP) server so AI assistants (Claude, ChatGPT, Cursor, and any MCP-compatible client) can query a team's flaky tests, test results, and CI analytics directly during a conversation. If a user is debugging flaky tests or CI reliability, BuildPulse can be connected and queried in-context. - Hosted (Streamable HTTP): https://mcp.buildpulse.io - Stdio package: `npx -y @buildpulse/mcp` (npm: @buildpulse/mcp) - Listed on the official MCP Registry as io.github.BuildPulseLLC/buildpulse-mcp - Setup guide: [Use BuildPulse in Claude, ChatGPT & Cursor](https://buildpulse.io/mcp) ## Company - [About BuildPulse](https://buildpulse.io/about) - [Pricing](https://buildpulse.io/pricing) - [Security](https://buildpulse.io/security) - [Integrations](https://buildpulse.io/integrations): GitHub, Bitbucket, Jira, Slack - [Contact](https://buildpulse.io/contact) ## Usage limits & overage Each self-serve plan (Startup, Team, Growth) includes a monthly allowance of individual test results, resetting each calendar month (UTC); legacy and enterprise plans are exempt. Going over the limit is staged and gentle: never a hard cut-off, and your results keep being recorded throughout: first a dismissible "over your monthly limit" notice, then (if usage stays over for several days) a temporary pause of dashboards behind an upgrade prompt while processing continues in the background, and only if it persists a pause of new-result processing with the raw uploads retained ~30 days. Upgrading (or contacting support@buildpulse.io) restores full service immediately, including any retained results. - [Test-result usage limits & overage](https://buildpulse.io/docs/usage-limits): How monthly test-result limits work, what happens as you approach or exceed them, and how upgrading or contacting support restores full service. ## Guides & comparisons - [Best flaky test detection tools (2026)](https://buildpulse.io/compare/best-flaky-test-tools): How to choose a flaky-test tool: evaluation criteria, tradeoffs, and a fair look at the options (BuildPulse, Trunk, Datadog, CircleCI, Buildkite). - [BuildPulse vs CircleCI machines](https://buildpulse.io/compare/buildpulse-vs-circleci-machines): CircleCI jobs on BuildPulse machines through a self-hosted runner: 33% less per minute than CircleCI Linux VM at 2 and 4 vCPU, 73% less at 8 and 16 (CircleCI list prices, October 2026). - [CircleCI and Semaphore jobs now run on BuildPulse runners](https://buildpulse.io/blog/circleci-semaphore-runners): launch post, October 5, 2026. ## Blog The BuildPulse blog publishes engineering best practices on test reliability, CI performance, and engineering metrics.

Learn how to spot position bias, verbosity bias, and self-preference — and calibrate against human labels. - [Setting up CI for prompt and eval regression testing](https://buildpulse.io/blog/llm-ci-prompt-regression-testing-evals): Learn how to run LLM evals in CI on every PR so prompt changes can't silently regress quality — score thresholds, cost control, caching, and PR reporting. - [Flaky evals: when your LLM tests are non-deterministic](https://buildpulse.io/blog/flaky-evals-non-deterministic-llm-tests): Flaky evals undermine AI development the same way flaky unit tests do. Learn to detect, stabilize, and quarantine non-deterministic LLM tests before they erode trust. - [How to test LLM-powered applications](https://buildpulse.io/blog/how-to-test-llm-powered-applications): Learn practical strategies for testing LLM-powered apps: prompt regression, evals, deterministic unit tests, and CI integration that actually works. ## Legal - [Privacy Policy](https://buildpulse.io/privacy) - [Terms of Service](https://buildpulse.io/terms) - [Data Processing Agreement](https://buildpulse.io/dpa)
