Command a fleet of cloud agents as a team

One platform where developers, PMs, and designers plan visually, build, and safely ship together, on the codebase you already run. Parallel cloud agents do the work in the background.

“Love how it’s able to execute my plans in one-shot.”

VP of Engineering, Warmly.ai (Series A)

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.

  1. 1

    Describe what you want

    “Add a pricing page with a monthly/annual toggle.” “Move the CTA above the fold.” Plain English, not code.

  2. 2

    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.

  3. 3

    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.

  4. 4

    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”

Spec generated:

  • Monthly/annual toggle component
  • 3-tier pricing cards
  • Stripe checkout integration

Shipped to production

Built for shipping teams

What your team gets.

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

Why Lightsprint, why 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: requirements, planning, parallel cloud agents, live previews, pull-request review, and post-release metrics. All on the codebase you already run.

Who uses Lightsprint? Engineers, PMs, designers, or all of them?

All of them. Engineers stay in their normal Git workflow and review pull requests. PMs and designers describe changes in plain English with visual options, then route to engineering for review. Ops and managers get a real-time project board across the whole team.

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 all participate, parallel cloud agents run in the background (not on a developer's laptop), and every change is a pull request grounded in your real codebase.

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, not a clone, and not a prototype tool.

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 your workspace, not in any single model provider.

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 across different requirements with cross-agent conflict prevention, and the project board updates in real time as each one completes.

What does the end-to-end workflow look like?

Describe the change, review the plan, run parallel cloud agents in the background, preview live, review and approve PRs, ship to production, see the metric impact. Every step shares one workspace and feeds context into the next.
