Trevo vs LaunchDarkly
LaunchDarkly is where enterprises manage feature rollouts. Trevo is how experiments get created in the first place — written as pull requests by an agent that read your repo.

Trevo or LaunchDarkly — which should you choose?
Choose LaunchDarkly when you want a feature management platform and have a team ready to implement the variants. Choose Trevo when implementation is the constraint: Trevo produces the experiment: a grounded proposal from your code, a pull request with the variant and assignment already wired, always-valid statistics with guardrail auto-pause, and a cleanup PR that keeps the codebase honest when the experiment is called.
What LaunchDarkly does well
LaunchDarkly is the market standard for feature management: progressive rollouts, targeting, guarded releases, and an experimentation capability layered on its flags, trusted at serious enterprise scale.
Where LaunchDarkly stops
Its experiments inherit the flag model: your engineers conceive the test, build every variant behind a flag, and own the eventual cleanup — the platform manages state, it does not produce experiments. Flag debt is a famous enough problem that cleaning it up is an industry pastime.
What Trevo does differently
Trevo produces the experiment: a grounded proposal from your code, a pull request with the variant and assignment already wired, always-valid statistics with guardrail auto-pause, and a cleanup PR that keeps the codebase honest when the experiment is called.
At a glance

|---|---|---|
| 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 |
| Primary job | Running experiments end to end | Managing feature rollout state |
| Where winners end up | Merged into your repo like any other change | Behind flags until cleaned up |
| Losing variants | Removed by an automatic cleanup PR | Manual flag cleanup |
| Statistics | mSPRT, always-valid — peek anytime | Experimentation add-on on flags |
Choose LaunchDarkly if
- –You need enterprise-grade release management: progressive rollouts, kill switches, targeting.
- –Experimentation is secondary to safely shipping features.
Choose Trevo if
- ✓You want a steady stream of experiments without staffing one.
- ✓You want variants written, wired, and cleaned up as PRs.
- ✓Your tests target revenue logic, not rollout mechanics.
Frequently asked questions
Is Trevo a LaunchDarkly replacement?
Not for release management — LaunchDarkly excels there. For experimentation, Trevo replaces the part LaunchDarkly leaves to your team: inventing, writing, wiring, and cleaning up the experiments themselves.
Can the two coexist?
Yes. Trevo experiments are self-contained code changes with their own assignment via the Trevo SDK, so they sit alongside an existing flag system without touching it.
How does Trevo avoid flag debt?
Every experiment ends with a decision, and every decision produces a cleanup PR that removes the losing path — the codebase never accumulates dead branches.
