Build real features on your actual product, with your whole team.
Your data, your components, your design system.
With Else, we went from validated prototype to production PR in a fraction of the time it used to take.
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.
How it works
Prototype
- Install the Else GitHub app on your frontend repo
- Answer a few questions
- Done! Start hacking on top of your product.
Live user test
- Integrate our lightweight client SDK
- Set up server-to-server integration
- Done! Run live user tests with zero engineering involvement
Ship to production
- Else opens a PR, ready for review
- New backend work comes with a full spec
- Done! Engineering reviews, tests, and merges. No rebuild.
Built for your whole team
Ship changes on your actual product.
Build the change on your real product, test it with real users, and ship before the next sprint.
- Validate the bet before it takes a sprint.
- No spec-to-Figma-to-ticket translation loss.
- What you tested is what ships.
