Catalog comparison
Flakiness.ioTestmo
Side-by-side facts from the TestGuild Tool Matcher catalog. Empty cells mean the catalog does not list that attribute — not that the product lacks it.
CI test analytics for GitHub and GitLab that separates regressions from flaky tests by tying every result to commit and environment. Ingests results from Playwright, Vitest, Pytest, Jest, CucumberJS, Bun, Rust, JUnit XML, and custom reporters; merges shards into one report; balances shards by historical duration; stores logs, screenshots, videos, and Playwright traces; and exposes compact failure context for coding agents. Freemium SaaS priced by artifact storage (not seats or runs), with optional self-hosting.
Testmo is a unified modern test management software that combines test case management, exploratory testing sessions, and test automation reporting in one platform. It features lightning-fast UI, rich reports, and extensive integrations with Jira, GitHub, GitLab, and many more tools.

Questions to verify before choosing
- Confirm current pricing and packaging on the Flakiness.io and Testmo websites.

- Verify the exact browser, device, or OS matrix you must support.
- Check what the free trial actually includes (users, minutes, devices).
