Features

As simple as it gets.

Native scale-to-zero

Uses App Runner, Cloud Run and Containers - no Kubernetes or custom runtimes. Apps sleep when idle, wake on the next request. Cold starts in 1-5 seconds on Cloudflare and GCP. Instant on AWS.

Bring Your Own Cloud

Deploy to your own GCP, AWS, or Cloudflare account. Nothing to install upfront. Your API token stays on your machine.

Any Docker app

Push local docker image, directly to the cloud and run. Declare what you need. Relight provisions the right service per cloud and injects credentials as env vars.

Same DX across clouds

One CLI, one workflow. Deploy, migrate, and manage apps the same way whether you're on Cloudflare, AWS, or GCP.

The economics

Stop paying for apps
nobody uses.

Scale-to-zero means sleeping apps cost nothing. Only pay when traffic arrives.

20 apps on traditional hosting $140/mo

20 apps × $7/mo each, all running 24/7

20 apps on Relight ~$5/mo

18 sleeping, 2 active - you only pay for what runs

The question changes from "is this worth $7/month?" to "just deploy it - it's free until someone uses it."

Bring your own cloud

Your cloud. Nothing installed.

Paste a cloud API token, deploy. No vendor infrastructure in your account. You pay the provider directly.

Porter 20-30 min

K8s cluster, 4+ EC2 nodes, VPC - $225/mo minimum

Flightcontrol 10-20 min

CloudFormation stack, VPC, ECS cluster, ALB, ECR

Coherence 10-35 min

IAM AdministratorAccess, VPC, ECS/Cloud Run

Relight <2 min

Nothing installed. Paste a token, deploy. $0.

No pre-provisioning. No CloudFormation, no Kubernetes. The CLI talks directly to cloud APIs.

Nothing to uninstall. Delete your apps, revoke the token, done.

How it works

Three steps. One CLI.

Connect

Paste your cloud API token. Cloudflare, GCP, AWS - one command to authenticate.

Deploy

Any Docker app. Relight builds the image, pushes it to your registry, and deploys. You get a URL.

Sleep & wake

No traffic? Your app sleeps. Cost drops to zero. Next request wakes it.

Infrastructure

Mix and match across clouds.

Every layer can run on a different provider. Use one cloud end-to-end, or pick the best of each.

Layer	Cloudflare	AWS	GCP
DNS	✓	✓	✓
LB	Workers	CloudFront	Cloud LB / Global LB*
APP	Containers	App Runner**	Cloud Run
DB	D1	RDS	Cloud SQL

* GCP Global Load Balancer has a ~$18/mo flat minimum. Cloudflare Workers and AWS CloudFront are usage-based.
** Not true scale-to-zero. ~$2.55/mo minimum per idle app, but no cold starts.

Example stacks

One cloud

Simplest deploy

DNSGCP

LBGCP

APPGCP

DBGCP

One API key, one bill. Everything runs in the same cloud with low latency between services. The simplest setup when you're already on a provider or just getting started.

DNS separate

Separate infra without moving DNS

DNSCloudflare

LBAWS

APPAWS

DBAWS

Keep your domain on Cloudflare for free DNS and edge caching, while running compute and database on AWS. Common when you already manage DNS on Cloudflare but want AWS infrastructure.

Compute separate

Best pricing

DNSCloudflare

LBCloudflare

APPGCP

DBGCP

Cloudflare Workers as a free global load balancer at the edge, with GCP Cloud Run for compute and Cloud SQL for the database. Combines two generous free tiers with GCP's flexible per-request pricing.

Cloud pros and cons

Cloudflare

+ Free tier on Workers and Containers
+ Global load balancing included
+ Fastest cold starts
- Database limited to D1 (SQLite)
- Containers still in beta
- Priciest above free tier, complex billing

AWS

+ No cold starts
+ Full database support (RDS, DynamoDB)
+ Pay-per-use global load balancing
+ Largest cloud ecosystem
- ~$2.55/mo minimum per idle app
- No free tier for compute

GCP

+ Free tier on Cloud Run
+ True scale-to-zero
+ Full database support (Cloud SQL)
+ Most competitive pricing
- No pay-per-use multi-region LB
- Slowest cold starts (up to 5s)

Instant deploy

Make it live. No cloud account needed.

No API keys, no cloud setup. Deploy to Relight-hosted infra and get a real URL - without running anything on your machine.

terminal

$ relight deploy myapp .

No cloud configured - deploying to relight.run

Building image...

--> Live at https://myapp-a1b2.relight.run

↓ Accessible from your IP only.

$ relight allow 203.0.113.10

Added. 2 IPs can now reach myapp.

Not localhost. Your app runs on real infrastructure with a real URL - no port-forwarding, no tunnels, no “works on my machine.”

IP-locked by default. Only your IP can reach it. Add more IPs for teammates or beta testers.

No keys required. Skip cloud setup entirely. When you’re ready for production, migrate to your own cloud with one command.

Migration

Move between clouds
in one command.

Start on Cloudflare, move to AWS or GCP. Switch back. Relight migrates your app, containers, env vars, and databases.

migrate to

$ relight apps

myapp GCP running

$ relight migrate --compute aws

Migrating myapp:

Image → ECR (us-east-1)

Env vars → App Runner

Database → RDS (pg16)

Done. Live at https://myapp.us-east-1.awsapprunner.com

Old deployment on GCP removed.

$ relight apps

myapp AWS running

$ relight migrate --compute gcp

Migrating myapp:

Image → Artifact Registry (us-east1)

Env vars → Cloud Run

Database → Cloud SQL (pg16)

Done. Live at https://myapp-abc123.run.app

Old deployment on AWS removed.

$ relight apps

myapp GCP running

$ relight migrate --compute cf

Migrating myapp:

Image → Cloudflare Container

Env vars → Worker binding

Database → D1 (pg-compat)

Done. Live at https://myapp.your-domain.workers.dev

Old deployment on GCP removed.

No vendor lock-in. Deploy to Cloudflare today, move to GCP or AWS tomorrow. Your app isn’t tied to any provider.

Databases move too. Relight migrates your managed addons - Postgres, KV, object storage - to the equivalent service on the target cloud.

Fast. Relight re-pushes your image to the new registry, provisions services, and cuts over. Minutes, not days.

Comparison

Scale-to-zero + Docker + BYOC.

Most platforms give you one or two. Not all three.

Platform	Scale to zero	Docker	BYOC	DX
Heroku	No	Yes	No	Great
Fly.io	Partial	Yes	No	Great
Railway	No	Yes	No	Good
Render	Partial	Yes	No	Good
Vercel / Netlify	Yes	No	No	Great
Coolify / Dokku	No	Yes	VPS	OK
Relight	Yes*	Yes	Yes	Great

* True $0 on Cloudflare and GCP. AWS App Runner: ~$2.55/mo minimum when idle, with instant wake (no cold start).
