Turn insights into features
that drive metrics

Describe the change, agree on a visual plan and preview it live. Engineering approves every merge.

Shorten the onboarding flow.

Ship what customers
actually want.

You know what needs to change. LightSprint takes it from the request to a reviewed pull request without a chain of handoffs.

Turn customer feedback into shipped features

Create tasks from Slack, Linear or Jira, where feedback already lands. Updates sync both ways while agents build.

Pressure-test product plans before you build

LightSprint breaks a requirement into a plan with tasks, dependencies and visual options. The team annotates and approves it before any code is written.

Prototype on your real codebase

Every change gets a live preview URL running the actual code, so sales and customers can click through a working prototype instead of a mockup.

Now everyone on your team can ship.

Describe the change in plain English. LightSprint builds it, spins up a live preview, and prepares for engineering review.

The software factory trusted by teams

We've been able to now accelerate product development dramatically by allowing PMs and designers to ship. Love the collaborative process on LightSprint!

We run dev and BD workflows on LightSprint - shared agent sessions and per-task previews eliminated the handoff friction between teams. Founding team is super responsive too.

Managing agents with LightSprint is a game-changer as we can share the same agent sessions and steer together. Feels like Google docs for agents.

We send tickets from Linear and Slack directly into LightSprint, and its agents use our team’s shared skills and context to help build features, triage bugs, and work through the engineering backlog much faster.

First day live: 4 pull requests with real features from our (non-engineer) Product Lead - I've messaged 3 separate friends "This is the future of software engineering". Takes a day to set up, once set up anyone can create a task which gives them their own environment with Lovable style side chat.

What impressed me is the way LightSprint helps with the planning process - designers, pms and devs can come up with a really good spec before giving it to an agent to one-shot.

LightSprint's plan mode allows me as a non-technical builder come up with different design variations for stronger alignment with my team.

Coding agents run solo in one developer's IDE while the rest of the team falls out of sync. LightSprint is rebuilding the SDLC for the AI era.

Frequently asked questions

How is LightSprint different from Claude, Codex, or Cursor?

Claude, Codex, and Cursor are coding agents. LightSprint is the workspace that lets your entire product team use them together.

Instead of agent sessions living with one developer, LightSprint gives your team shared context, shared skills, cloud sandboxes, live previews, automated verification, and an approval workflow before anything ships.

You can keep using the models and coding tools you already like — LightSprint adds the collaboration and guardrails around them.

Is LightSprint more expensive than using AI models directly? Can I use my existing subscription?

LightSprint doesn't mark up model inference.

Bring your own API keys or use existing Codex and Claude subscriptions, or choose another model through OpenRouter. You're paying LightSprint for the infrastructure around the models: cloud execution, shared context, previews, collaboration, testing, and team controls.

How secure is LightSprint? What happens to our code and data?

Your team controls which repositories and models LightSprint can access.

Work runs in isolated cloud sandboxes, and those environments are destroyed after the work is complete. You choose the model provider, and LightSprint can also work with your own LLM gateway.

Every code change remains auditable through your existing GitHub workflow, and nothing can bypass the approval rules your engineering team configures.

What tools does LightSprint support? Will it fit into our existing workflow?

LightSprint is built to work with the stack you already have rather than replace it.

Connect your existing codebase and repositories, keep your GitHub review and CI workflows, and use agents like Claude and Codex. Your team can also send work into LightSprint from tools such as Slack and Linear.

Engineering sets up the environment, shared skills, and guardrails once, then the rest of the team can build within those constraints.

I'm not an engineer. Can I actually use LightSprint safely?

Yes — that's one of the main reasons LightSprint exists.

You describe what you want in plain English, plan the change visually, launch an agent, and review the result in a live sandbox without needing to understand Git or set up a development environment.

Non-engineers don't get a shortcut around engineering. Every change follows the approval workflow your team configures, so engineers still control what reaches production.
