Agentic-first IDE

Develop with

The AI-native IDE that puts you back in control. See your code as diagrams, turn small specs into full technical ones, and get architecture and code review built in, not bolted on.

The problem

You're a passenger in
your own codebase.

Agentic tools promised speed. Too often they put you in the back seat — watching code scroll past while something else drives.

  • You lose understanding of your own code.
  • You're constantly context-switching.
  • It's boring.
  • You're stuck in the terminal, talking to a chatbot.
  • Building harnesses isn't fun.
The turn

Take the wheel.

LightFactory hands you the diagrams, specs, and reviews to understand what's being built. AI still does the miles — you decide where it goes.

How it works

Small spec in.
Whole system out.

Sketch a few lines of intent. LightFactory expands it into a full technical spec, renders your architecture, and reviews both — no harness, no .md setup.

Capabilities

Everything you need to stay in the driver's seat.

Four things LightFactory does the moment you open your codebase.

Live product view01Visualize

See your code as a living diagram.

Interactive C4 diagrams across all four levels — context, containers, components, and code. Re-rendered from your actual codebase, never a stale wiki.

02Specs

Write a little. Get the whole spec.

A few lines of intent become a structured technical spec — data models, API surface, edge cases — ready to build against and easy to change.

03Architecture review

Catch design problems before you build.

LightFactory reviews the shape of your system — coupling, boundaries, missing pieces — and flags what needs attention, with the diagram to back it up.

04Code review

Every change, reviewed in context.

Not just a diff. LightFactory reviews each change against the architecture it already understands — and tells you why, in plain language.

The pillars

Develop with all four.

The words in the headline aren't a mood — they're what the tool is built to give you.

01

Pleasure

Development should feel good.

A workspace built for flow, not friction. Diagrams instead of dread, and the joy of building back where it belongs.

02

Understanding

See the whole system.

Every change shown in the context of the architecture around it. You're never guessing what the agent just did.

03

Confidence

Ship without flinching.

Architecture and code review built in — so you know what you're shipping is sound before it ever goes out.

04

Speed

Momentum, not setup.

No harness-building, no .md scaffolding. Best-practice agentic flows the moment you open a project.

On the roadmap

Clarity doesn't stop at code.

What we're building next — turning the work you'd normally dread into one more thing you can simply see.

Soon

GDPR report

Know exactly where personal data flows through your system — generated, not hand-traced.

Soon

Compliance report

Map your architecture against the standards you answer to, and see the gaps early.

Soon

Infrastructure surveillance

Watch your live infrastructure for drift, risk, and surprises against the design of record.

And more

We're just getting started.

The factory keeps building. Take the wheel now and grow into everything that's coming.

AI is a bicycle for
your brain again.
