Build packs

Auto-detect or bring your Dockerfile.

Push a repo, we figure out the build. Or commit a Dockerfile if you have something specific. Either way, builds are aggressively cached and run on your project's own ephemeral pool.

Auto-detection covers Node, Bun, Next, Astro, Remix, SvelteKit, Vite, Python, Django, FastAPI, Rails, Phoenix and more
Layer cache hits typically rebuild a Next app in under 40 seconds
BuildKit + secrets injection for Dockerfile flows

Preview

A unique URL for every pull request.

Open a PR, get a preview environment with isolated secrets and an optional branch database clone. Comment in GitHub, share with QA, tear down on merge.

Autoscale

Scale on signals you actually care about.

RPS, CPU, queue depth, custom metric, schedule. Mix and match across services so your worker pool grows with your queue, not your web traffic.

Scale to zero on idle for non-critical services
Custom metrics fed from Prometheus or your own webhook
Burst pool absorbs flash traffic without page-out

Growth

Teams that ship before lunch.

Indie SaaS team of three

Replaces Heroku for $0 → $35/mo

Pushes to GitHub, gets a per-PR preview URL with a clone of staging Postgres. Production runs at 2x the throughput, on a quarter of the bill.

API team at a fintech

Internal microservices on a tight SLA

Service mesh, mTLS by default, per-service auto-scale tied to upstream queue depth. P99 latency under 80ms across 14 internal APIs.

Bootcamp instructor

60 students push their first deploy

Each student gets a Starter project with three preview branches. Zero credit cards, zero ops — class focus stays on the code.

FAQ

The build, deploy and scale questions.

Which build packs are included?

Node 18/20/22, Bun 1.1, Python 3.10–3.13, Go 1.22, Rust stable, PHP 8.2/8.3, Ruby 3.2/3.3 and .NET 8 — plus a Dockerfile path if you want full control. Auto-detection handles 90% of repos out of the box.

How does autoscaling decide?

By default, on RPS and CPU. You can switch to queue depth, custom metric or scheduled scaling. Cold-start on a 512 MB Node service is around 280ms.

Can I run cron jobs and workers?

Yes — schedule cron jobs from the dashboard or repo, and run worker services that scale independently of your web service. Both are billed by the active minute.

Do you support Docker images?

Absolutely. Push a Dockerfile, push a built image to our registry, or pull from any public/private registry. Multi-stage builds are cached aggressively.

How do preview environments work?

Every pull request spins up a full preview with a unique URL, isolated env vars and an optional branch DB clone. The preview is torn down when the PR closes.

What about secrets and config?

Per-environment secrets (dev / preview / staging / prod) with envelope encryption. Supports SOPS, sealed-secrets and OIDC federation to GitHub Actions.
