Ship like a team 10x your size with cloud agents

The software development lifecycle was built for the old era, when humans wrote every line. Lightsprint powers the AI software development lifecycle for the agentic era, where fleets of cloud agents plan, build, and ship alongside your team.

A minute on what makes Lightsprint different: plan visually, fire off cloud agents, preview live, ship a real pull request.

Works with the tools your team already runs

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. Build. Ship.

1

Collaborate on a plan, visually

Describe what you want in plain English. Lightsprint reads your codebase and shows trade-offs and visual options styled to your actual app, so you can align with your team before anything gets built.

2

Build with background agents

Pick the plan and parallel cloud agents one-shot it in the background. Kick off the change and keep working. No babysitting a terminal.

3

Preview and Ship

Every change gets a live URL to click through like a real user. When it's right, Lightsprint opens a pull request for your engineers to review and merge.

"Add a pricing page with options"
Lightsprint generates options:
Tabs
Toggle
Slider
You pick "Toggle"
Spec generated:
  • Monthly/annual toggle component
  • 3-tier pricing cards
  • Stripe checkout integration

Ship the right features faster.

Ship faster

Increase engineering velocity

  • Run background cloud agents in parallel
  • Requirement → spec translation with codebase context
  • Instant previews
  • Live team collaboration

Expand capacity

Let non-engineers ship code safely

  • PR review hub
  • Codebase health monitoring
  • Plans grounded in real code context
  • Organisational guardrails

Build the right things

Focus engineering on what matters

  • Plan mode for upfront alignment
  • Critique skills (e.g. gstack)
  • Organisational context ("brain") that learns what your users want
Why should you use Lightsprint

Built for how teams ship now.

🧠

Compounding institutional memory

Every plan, requirement, task breakdown, and decision feeds a growing memory of your codebase, patterns, and preferences. The more your team builds with Lightsprint, the better it nails complex, long-horizon work in one shot.

🔌

Model- and tool-agnostic by design

Frontier labs build coding agents locked to their own models. Point tools cover only one slice of the cycle: coding, review, planning, or launch. Lightsprint works across all of them, so you're never locked in.

🏗️

Built for the codebases you actually have

Most AI coding tools shine on greenfield prototypes but break down on real production codebases: legacy patterns, real users, team conventions. Lightsprint is designed from day one for the messy reality of teams shipping software customers depend on.

Questions

What teams ask before they switch.

What is Lightsprint?
Lightsprint is an AI-native product platform where developers, PMs, and designers plan, build, and ship software together. One workspace covers the full cycle: describe a change, review a visual plan, run parallel cloud agents to build it, preview it live, and open a pull request your engineers review and merge.
How is Lightsprint different from Cursor, Copilot, or Claude Code?
Coding assistants like Cursor and Copilot are single-developer tools that live inside the IDE. Lightsprint is a multi-stakeholder platform — PMs, designers, and engineers work together across the whole cycle, from plan to merged PR, not just code completion.
Does Lightsprint work on my real codebase, or is it a sandbox?
Real codebase. Lightsprint reads your existing repository, follows your patterns and conventions, and pushes through your existing Git provider. It's not a sandbox or a fresh app — it works on the product you already run.
Are we locked into a specific AI model?
No. Lightsprint is model- and tool-agnostic by design. You can swap underlying models as the frontier moves. Your plans, decisions, and codebase memory live in Lightsprint, not in any one model.
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 and keep working on something else. Multiple cloud agents run in parallel in the background, so a whole plan can land in one shot.
