Trevo vs Statsig
Statsig is infrastructure for teams that run their own experiments. Trevo is an agent for teams that need help creating and implementing those experiments.

Trevo or Statsig — which should you choose?
Choose Statsig when you want a developer experimentation platform and have a team ready to implement the variants. Choose Trevo when implementation is the constraint: Trevo covers that missing half. It scans the repo, proposes experiments grounded in real files with server-side bets ranked first, writes each variant as a pull request, measures with always-valid mSPRT statistics, auto-pauses on guardrail breaches, and opens the cleanup PR when the result is called.
What Statsig does well
Statsig combines feature gates, experimentation, product analytics, and warehouse-native options. Its SDKs support both client- and server-side code, while its console manages targeting and results.
Where Statsig stops
It is a toolkit, deliberately: your team supplies the hypotheses, writes every variant, wires every flag, and remembers every teardown. The work that makes experimentation expensive — deciding what to test and building it — stays on your roadmap.
What Trevo does differently
Trevo covers that missing half. It scans the repo, proposes experiments grounded in real files with server-side bets ranked first, writes each variant as a pull request, measures with always-valid mSPRT statistics, auto-pauses on guardrail breaches, and opens the cleanup PR when the result is called.
At a glance
| Trevo | Statsig | |
|---|---|---|
| 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 |
| Flag/experiment wiring | Written into the PR for you | Hand-wired per experiment |
| 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 | Sequential testing, CUPED options |
Choose Statsig if
- –You have engineers who want to design and build every experiment themselves on strong infrastructure.
- –You need product analytics and feature flags in the same platform today.
Choose Trevo if
- ✓Ideation and implementation — not infrastructure — are your bottleneck.
- ✓You want proposals grounded in your actual code, delivered as PRs.
- ✓You want the flag hygiene problem to not exist: cleanup arrives as a PR.
Frequently asked questions
Is Trevo a Statsig alternative?
They solve different halves of the problem. Statsig is infrastructure your team experiments on; Trevo is an agent that does the experimenting — proposing, writing the PR, measuring, and cleaning up. Teams switch to Trevo when engineering time, not tooling, is the constraint.
Can Statsig and Trevo both run server-side tests?
Yes. Statsig SDKs can assign experiments in server-side code, and Trevo can implement variants in those same code paths. The practical difference is who produces the variant: your engineers with Statsig, or Trevo through a pull request your engineers review.
Does Trevo also provide the SDKs and stats?
Yes. Assignment resolves locally through Trevo SDKs for JavaScript/TypeScript, React, Python, and Ruby, and results use always-valid mSPRT statistics with guardrail auto-pause.
