Trevo or GrowthBook — which should you choose?
Choose GrowthBook when you want a open-source experimentation platform and have a team ready to implement the variants. Choose Trevo when implementation is the constraint: Trevo generates the pipeline itself: repo-grounded proposals with server-side changes ranked first, variants delivered as pull requests, mSPRT statistics you can peek at any time, guardrail auto-pause, and cleanup PRs for the losers.
What GrowthBook does well
GrowthBook offers feature flags and experiment analysis you can self-host, reading metrics from your own warehouse. It is transparent, affordable, and popular with teams that want control over their stack.
Where GrowthBook stops
Like every platform in its class, it runs what you build. Hypotheses, variant code, flag wiring, and teardown are your team’s job; the platform measures what you managed to ship.
What Trevo does differently
Trevo generates the pipeline itself: repo-grounded proposals with server-side changes ranked first, variants delivered as pull requests, mSPRT statistics you can peek at any time, guardrail auto-pause, and cleanup PRs for the losers.
At a glance
| Trevo | GrowthBook | |
|---|---|---|
| Who finds the opportunity | Trevo, from a scan of your repo and site | Your team |
| Who writes the variant | Trevo — every experiment arrives as a pull request on a trevo/* branch | Your engineers |
| Hosting model | Managed service | Self-host or cloud |
| Where winners end up | Merged into your repo like any other change | Your repo, after your own follow-up work |
| Losing variants | Removed by an automatic cleanup PR | Manual flag cleanup |
| Statistics | mSPRT, always-valid — peek anytime | Bayesian or frequentist on your warehouse |
Choose GrowthBook if
- –You want an open-source, self-hostable stack and full control of the pipeline.
- –Your metrics must be computed in your own warehouse.
Choose Trevo if
- ✓You want experiments proposed and implemented, not just measured.
- ✓Nobody on the team has time to write and tear down variants.
- ✓You want one system to go from repo scan to merged winner.
Frequently asked questions
Is Trevo open source like GrowthBook?
The platform is a managed service; the SDKs ship with your application code. What stays yours regardless is the output — every variant Trevo writes lands in your repository under your review.
Can Trevo work alongside an existing GrowthBook setup?
Trevo runs its own assignment and statistics through its SDKs, so it operates independently. Teams typically point Trevo at the surfaces their existing stack never gets to — the server-side backlog.
What does Trevo do that a flag platform cannot?
It does the work between idea and flag: reading your code, proposing grounded experiments, writing the variant as a PR, and cleaning up when the result is in.
