Ship the product change yourself, not in the next sprint.
Lightsprint is the AI product workbench for PMs and engineers. Describe a change in plain English, see visual options styled to your real app, preview it live, and safely ship a real pull request, as if you were working in a sandbox, no ticket required.
“Love how it’s able to execute my plans in one-shot.”

The problem
Cloud agents are here.
The workflow to steer them isn’t.
Background agents code faster than ever, but you can’t see what they’re doing until the PR lands. Plans arrive as walls of text. PMs and designers are locked out. Work ships fast, then ships wrong. Lightsprint gives the fleet a real workflow: visual plans the whole team aligns on, live previews while it builds, and a way to course-correct before it’s too late.
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.
Pick the right plan
Each plan is visual, not a wall of text. See UI options styled to your app with a full working preview before you approve. Pick one and cloud agents one-shot from there.
Preview live and ship
Every change gets a live URL. Click through it like a real user. When it’s right, ship the pull request to your real codebase.
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
An AI coding tool for product managers, without the engineering bottleneck. Describe the change, pick from visual options styled to your app, ship it to a preview environment. Engineers still review the PR before it merges 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.
Before & after
From idea to merged PR.

Questions
What teams ask before they switch.
What is Lightsprint?
Lightsprint is an AI product workbench where engineers and product managers ship to a real codebase together. PMs describe changes in plain English, see visual options styled to the actual app, preview every change live on a unique URL, and ship a real pull request that engineers review and merge.
How is Lightsprint different from Lovable, Replit Agent, and Bolt.new?
Lovable, Replit Agent, and Bolt.new build new apps from prompts. Lightsprint works on your existing product. Same repository, same database, same users. Every change is a pull request your engineers review before anything touches production, so you keep your real architecture, infrastructure, and Git workflow.
Can product managers actually ship code with Lightsprint?
Yes. PMs describe what they want in plain English, pick from visual options styled to the live app, and push the change to a preview environment. Engineers review the PR before it merges to production. PMs don't have to write code, and engineers stay in control of what ships.
Does Lightsprint work on my real codebase, or is it a sandbox?
Lightsprint reads your real repository and makes changes that fit the patterns your team already uses. It's not a clone, not a sandbox, and not a prototype tool. Every change runs against your actual app and ships through your normal pull request review.
How does the visual planning step work?
Before any code is written, Lightsprint shows trade-offs and UI options styled to your actual app: buttons, layouts, and components that match your design system. You pick the version you want, then the cloud agent executes one-shot from a plan that's already correct, which means fewer revision loops and faster shipping.
Do agents run in the background, or do I have to wait?
Cloud agents run in Lightsprint's infrastructure, not on your machine. Kick off a change, close the tab, and come back to a live preview when it's ready. You can have multiple changes building in parallel (different requirements, different PRs) without any of them blocking the others.
What does the end-to-end workflow look like?
Describe the change, review the visual plan, preview it live on a unique URL, and open a pull request. Engineers review and merge through their normal Git workflow. Nothing ships to production without their approval. Lightsprint replaces the ticket-and-wait loop, not the engineering review.
