Prototype and test inside your actual product
Ship a PR engineers actually merge
You know what needs to change. You've designed it, validated the concept, maybe even built a Figma prototype that everyone loved. Then it goes into the backlog. Then it waits weeks or months—your validated prototype stuck in a Figma file, the customer conversation forgotten.
Else fixes that.
With Else, your PR is review-ready in minutes, running on the real codebase, with zero rework. Engineering doesn't rebuild. They review, test, merge. What shipped in the prototype is what ships to users.
90% faster to production. PRs merged with zero changes.
'With Else, we went from validated prototype to production PR in a fraction of the time it used to take. Engineering didn't touch it until it was ready to merge.'
— Drew Muller, Ferry International
From zero to live
Build directly on your real product.
Prototype on your actual product — not a copy of it.
Static mockups lie. They don't have your real data, your real components, or your real edge cases. Else runs inside your live product, so what you're testing is exactly what your users will see. No more 'it looked different in Figma.'
Build working features
There are no limits with Else. A single prototype can live across multiple pages and completely rework UX and backend interactions.
Match your design system
Else learns from your code base to inherit your design system and re-use existing components. It just works.
Full stack
Want to add new backend functionality? Else extends your backend without modifying it, including a new data layer.
Ship what works
Ship what works, rework what doesn't. Improve your KPIs while keeping your product free from the bloat and carry cost of unused features.
Hand over a PR, not a brief.
When your prototype works, Else opens a frontend PR ready for engineering review. The polish you got right stays right. For new backend functionality, you get a full spec and an integration prompt. Engineering's job becomes: review, test, merge. No more starting from scratch. No more losing the details in translation.
Full backend spec
Export a full spec for new backend functionality, along with a prompt to integrate it in your real backend.
Prototype to production in a jiffy
With a ready PR and a clearly defined target, your engineering team can ship to production FAST.
