Vitalgate vs SpeedCurve
SpeedCurve is a full monitoring platform with its own real-user monitoring and synthetic tests, built for teams that study performance closely. Vitalgate is narrower: it enforces budgets on every pull request so regressions don't ship, with a free plan for one repository.
| Feature | Vitalgate | SpeedCurve |
|---|---|---|
| Main job | Block regressions in pull requests | Monitor and analyse performance in depth |
| Pull request checks | Built in: a GitHub check and a results comment | Through its deploy API and CI integrations |
| Real-user data | Chrome UX Report (p75, 28 days) | Its own RUM, page-view level |
| Synthetic tests | Median of three Lighthouse runs per pull request | Scheduled, many locations, filmstrips |
| Free plan | Yes, 1 repository | No |
| Price | Free for 1 repository; Pro is $29/month per workspace for unlimited repositories. | From $90/month |

What a pull request gets from Vitalgate
A results comment, updated on every push, and a "Vitalgate" check that fails when a required budget is broken. Make the check required and the pull request can't be merged.

Depth vs guardrails
SpeedCurve gives performance specialists detailed RUM, filmstrips and competitive benchmarks. Vitalgate gives every developer a pass or fail on their own pull request. One helps you understand performance; the other keeps it from getting worse with each merge.
Where SpeedCurve is stronger
Its own real-user monitoring works on any site with the snippet installed, including low-traffic and logged-in pages, and its synthetic testing is far more detailed. Vitalgate's real-user view needs the site to be in the Chrome UX Report.
