Live runtime · no redeploys

Build it.
Run it.
Change it live.

Run it once. Change it instantly. No redeploys.

Backend, workflows, scrapers, bots — whatever you're building, it runs immediately and stays editable in real time.

— Stop redeploying

Stop redeploying every time something changes.

Run once. Then just change it.

✓Update logic live
✓Modify behavior instantly
✓Iterate without restarting your system

— Live runtime

A live runtime for your code.

Not scaffolding. Not templates. Not a sandbox.

Run APIs, workers, bots, and scrapers
Process real traffic in real time
Route and transform requests live
Keep systems editable while they run
— Change behavior live

Same request. New behavior.

Change the logic mid-flight. The next request just behaves differently.

Step 1 · Request
GET/user/123
→ { status: "pending" }
→
Step 2 · Logic changes
- status: "pending" + status: "active"

Step 3 · Same request
GET/user/123
→ { status: "active" }

— Real systems

Runs like production — because it is.

Real networking
Inbound and outbound, real ports.
Real traffic
Live requests, not mocks.
Real persistence
State that survives requests.
Real integrations
Talk to real services.

You're not simulating your system. You're running it.

— AI-generated code

Works with AI-generated code.

People are generating more software than ever. The bottleneck isn't writing code anymore.

✓Run what you just generated
✓Connect it to real inputs
✓Evolve it without friction
The bottleneck isn't writing code.
It's running it.
— Power features

Tunnels and replay, built in.

Built-in tunnels
→Expose local services instantly
→Webhook URLs, ready to use
→Route to localhost or LAN
→No per-host pricing
Request replay
→Replay real webhook traffic
→Debug integrations instantly
→Rerun requests after logic changes
— Dev loop

This replaces your dev loop.

Traditional
edit→deploy→wait→test
r3v
edit→live

Faster iteration. Fewer breaks. More control.

— Pricing

Simple pricing. Scales with you.

Each plan includes runtime and compute capacity. Most apps stay well within it. As usage grows, pricing scales transparently.
