Start shipping at the
speed of your ideas

LightSprint turns what your team describes in plain words into real software, the way a senior engineer would ship it.

LightSprint plan visually, build safely, and ship with team approval

Now everyone on your team can ship.

Describe the change in plain English. LightSprint checks it, fixes it, flags what's risky, no engineering background needed.

Build features safely in a sandbox

Built for the codebase you already have.

Lightsprint works with complex codebases across multiple repositories. Connect them, and it learns your conventions before proposing anything.

Template gallery, including a React Native app template with web and mobile support

Use existing codebase

Learns your structure and style, works inside your current stack with no migration or rewrite, and ships changes that fit the patterns your team already uses.

Pick from our templates

Use a template across different tech stacks, such as a full stack web app or a mobile application on Flutter.

MCP connectors wired up across your tools

Works with tools you already trust

Engineering sets up once,
scales to the whole team.

Shared Skills

Save a skill once design.md for your design system, review.md for code standards. Every teammate or AI agent can pull from it instantly.

Using postgres, matching your preferences and ability to handle both SQL and JSON unstructured data.

Shared Context

The AI already knows your codebase, past decisions, and conventions. No re-explaining, no knowledge trapped in one person's head.

Shared Execution

Every change runs in a live, shareable preview. Anyone on the team can hop in, watch it build, and weigh in. No local setup needed.

Ship the right
features faster.

Preview the result exactly as your users will see it, then ship with one click. Undo is always one click away.

Product

Ship what customers actually want

Turn customer feedback into shipped features
Pressure-test product plans before you build
Preview changes exactly as users will see them

Design

Make designs changes without waiting on engineering

Turn Figma designs into working frontend code
Explore design variations in parallel
Ship polish fixes yourself - copy, spacing and colors

Engineering

Increase velocity with parallel agents

Clear your bug backlog with background cloud agents
QA verification with automated screenshots
Consolidate feedback from code review agents

Trusted by teams building real software.

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. Like Google docs for agents.

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.

Can a non-engineer ship directly to production without review?

No. Every change goes through the approval workflow your team configures. There is no bypass.

What happens if a change breaks something after it ships?

Every change is tracked in GitHub, so your engineering team can identify the pull request and revert it through the same workflow they already use.

Does LightSprint send our code to external AI providers?

We send only the request and receive the response. You choose the model provider, and we can also support your own LLM gateway.

Can we require review from a specific person or team?

Yes, approval rules are configurable per role.

What's logged, and for how long?

Everything stays auditable in GitHub. Once the work is complete, the sandbox is destroyed and nothing is stored there.

How is this different from just requiring PR review in GitHub?

LightSprint enforces the same review discipline for people who don't work in GitHub at all — the gate exists regardless of whether they know what a PR is.
