FailBrief vs Flakiness.io

FailBrief has no write-up on Specifiction yet; its figures are above.

Flakiness.io provides test analytics for GitHub and GitLab, tracking outcomes across commits to distinguish flaky tests from regressions. It labels a test that alternates between passing and failing on the same commit as flaky, while persistent outcome changes at a commit count as regressions. Listed runners include Playwright, Pytest, Vitest, Jest, CucumberJS, Bun, Rust, and a JUnit XML bridge; a Node.js SDK supports custom integrations. The service works with any CI provider, ingests results as they arrive, merges shards, and separates staging and production histories. Reports include test history, grouped errors, system telemetry, and a test waterfall. Artifacts can include logs, screenshots, videos, traces, and HTML files. Recorded durations can help Playwright balance shards using historical runtime. Hosted plans include a Free option with 1 GB of artifact storage and 90 days of retention; Startup costs $49 a month with 10 GB and 180 days. Growth costs $199 a month. Self-hosting uses PostgreSQL and an S3-compatible object store. Customers must not upload specified sensitive data.
