Plan visually. Preview live.
Ship production-ready code.
Lightsprint is a product workbench where engineers and PMs ship together on your real codebase, not a prototype. Describe what you want, see visual options styled to your app, preview it live, and ship a real pull request.
No credit card. Works on your real repo.

The problem
Other AI tools start from scratch.
Your product already exists.
Lovable, Replit, and Bolt create new apps. But your product has a real codebase, real users, and real infrastructure. Coding agents help engineers write code faster, but your PMs still file tickets and wait. Lightsprint is where the whole team ships, on the product you already run.
How it works
Plan. Preview. Ship.
Describe what you want
“Add a pricing page with a monthly/annual toggle.” “Move the CTA above the fold.” Plain English, not code.
Plan visually
Lightsprint reads your codebase and shows trade-offs and visual options styled to your actual app. You choose before anything gets built. Agents execute one-shot because the plan is that good.
Preview live
Every change gets a live URL. Click through it like a real user. Multiple previews let your team compare real implementations before anything ships.
Ship it
Lightsprint opens a pull request. Your engineers review and merge, just like any other PR. Nothing touches production without their approval.
You say:
“Add a pricing page with monthly/annual toggle”
Lightsprint generates options:
Tabs
Toggle
Slider
You pick “Toggle”

Who it's for
Built for engineers and PMs
who ship together.
Engineers
Stop context-switching on small changes. Your PM drafts it with a visual plan, you review the PR. Focus on architecture, not copy tweaks.
PMs & Founders
Stop filing tickets. Describe the change, pick from visual options styled to your app, and ship it to a preview environment. Engineers review the PR before merging to prod.
Teams
Plan together. Compare multiple live previews. Ship production-ready code in hours, not sprints. Everyone sees what's being built.
Why Lightsprint
Not a prototype. Not a sandbox.
Your actual product.
Visual planning, not blank prompts
See trade-offs and UI options styled to your app before any code is written. Agents execute one-shot because the plan is that good.
Your real codebase, not a clone
Same repo, same database, same users. Lightsprint reads your existing code and makes changes that fit how your team builds. Nothing to rebuild.
Every change is a pull request
Your engineers review, refine, and merge, just like any other PR. Nothing touches production without their approval.
