Trevo vs Coframe
Coframe and Trevo are both AI-native. The difference is where the AI is allowed to work: Coframe edits your rendered pages; Trevo writes code in your repository.

Trevo or Coframe — which should you choose?
Choose Coframe when you want a AI conversion optimization agent and have a team ready to implement the variants. Choose Trevo when implementation is the constraint: Trevo connects to the repo itself. It snapshots your server logic, proposes experiments that cite files that exist, and writes each variant as a pull request your team reviews — front-end changes included, but ranked below the deeper bets. Winners merge; losers are removed by cleanup PRs; every claim it makes is checked against your code.
What Coframe does well
Coframe uses language models to generate copy and interface variations and applies them to your site through a JavaScript snippet, iterating toward better-performing pages with minimal setup — a fast way to put AI on top of a marketing site.
Where Coframe stops
A snippet can only touch what the browser renders. Pricing rules, API behavior, prompts, and ranking are out of reach; changes live in a vendor layer rather than your codebase; and your engineers never get a diff to review. The AI optimizes the paint, not the machine.
What Trevo does differently
Trevo connects to the repo itself. It snapshots your server logic, proposes experiments that cite files that exist, and writes each variant as a pull request your team reviews — front-end changes included, but ranked below the deeper bets. Winners merge; losers are removed by cleanup PRs; every claim it makes is checked against your code.

Choose Coframe if
- –You want AI iterating on a marketing site with zero engineering involvement.
- –A snippet-based setup with no repo access fits your constraints.
Choose Trevo if
- ✓You want AI experimenting on the product itself — pricing, flows, prompts — not just page copy.
- ✓Every change must arrive as a reviewable diff in GitHub.
- ✓You want the results to compound in your codebase, not in an overlay you rent.
Frequently asked questions
Trevo and Coframe are both AI CRO tools — what is the real difference?
Reach and custody. Coframe applies AI-generated variations to rendered pages through a snippet. Trevo reads your repository and writes experiments as pull requests, so it can test server-side logic and every winning change becomes code you own.
Is giving Trevo repo access safe?
Access is deliberately narrow: read on the repos you connect, write only to trevo/* branches, and merging is always yours. An append-only audit log records every experiment decision.
Can Trevo still optimize landing page copy like Coframe does?
Yes — front-end and copy experiments ship as code inside your components, without a snippet, alongside the deeper server-side tests.
