Keep this for your CFO

No runtime limits.

128 MB is all the memory a Cloudflare Worker gets. OpenOrange runs your Workers and Durable Objects on machines you choose, so the limits are your hardware's.

Limit Cloudflare Workers Paid OpenOrange
Memory per Worker or Durable Object 128 MB Up to your machine's memory Node.js heap: up to about 4 GB by default, configurable
CPU time per request 30 s default, 5 min max No cap

Open connections per request 6 at once OS limits
Storage per Durable Object 10 GB No cap

$ orange deploy --dry-run

Dry run. Nothing was built or sent to Rivet Cloud.

Get started.

  1. Step 1: Install

    Install the orange CLI globally, then run it in your Worker project. Your code and your Wrangler configuration do not change.

    $ pnpm add -g open-orange

  2. Step 2: Run your Worker

    Reads your Wrangler configuration. Each Durable Object runs as a Rivet Actor with its own SQLite database.

  3. Step 3: Deploy

    Builds an image of your Worker and rolls it out to your own cloud (AWS, GCP, Azure) or on-prem servers. Or use Rivet Cloud: a fully managed, dedicated cluster on AWS or Google Cloud, in the region you choose.

Migrate your data without downtime.

orange migrate copies every Durable Object and D1*Cloudflare doesn't provide a way to migrate D1 live, so requests to a D1 database are interrupted while its data copies. This takes a few minutes. database from Cloudflare while your app keeps serving. No maintenance window, no lost writes.

Migration guide

Supported bindings.

Every Cloudflare binding OpenOrange runs, plus the fetch handler and runtime globals. Each is documented with its status, configuration and known differences from Cloudflare.

Bindings documentation

Not built yet: Vectorize, Images, Pipelines, mTLS certificates. These bindings load, and each call throws an error that names the binding.

Questions.

Wait, wasn't Cloudflare supposed to be cheaper?

For small, spiky Workers, it often is: the free tier and per-request pricing are hard to beat. The meters add up once Durable Objects stay busy. Duration is billed per GB-second while an object is active, and every SQLite row written costs $1 per million. The same GB-hours on Graviton EC2 cost about a fifth as much, and writes cost a fraction of that.

Is OpenOrange a fork of Cloudflare?

No. OpenOrange implements the Workers API on Node.js and maps each Cloudflare service onto Rivet. It uses Wrangler to read your configuration, and it reuses some MIT-licensed Cloudflare code, such as the Workflows engine. It does not run workerd.

Why not just run workerd directly?

workerd is Cloudflare's runtime, not its platform. It runs your fetch handler, but KV, D1, R2, Queues, Workflows and the Cache API are bindings that call services you have to build, and Durable Objects keep their data on one machine with nothing to place, replicate or scale them. It also keeps limits designed around Cloudflare's network rather than your servers: only the nodejs_compat subset of Node.js, no native npm modules, and alarms capped at 15 minutes. OpenOrange runs your Worker on Node.js with real SQLite, and Rivet provides the services, so your code keeps working on infrastructure you control. Compare OpenOrange and workerd

Do I need to learn Rivet?

No. Rivet is the control plane underneath. You use the orange CLI and your Wrangler configuration.

What does it cost?

OpenOrange is Apache 2.0 and free. Self-host Rivet and your cloud bill is the only bill. Rivet Cloud and BYOC pricing is at rivet.dev/pricing.

What happens to the data already in KV, Durable Objects and R2?

orange migrate moves Durable Objects while your app serves, with no downtime. D1 databases are interrupted for a few minutes while they copy, because Cloudflare doesn't provide a way to migrate D1 live. R2 is S3-compatible, so rclone or aws s3 sync moves buckets.

Does it run at the edge?

It runs wherever you deploy it, in as many regions as you want. Most backends talk to one database; running next to it is faster than running at the edge. For stateless Worker requests, this works fine today. For Durable Objects, an upcoming Rivet update adds multi-region support, including edge regions.
