# Self-Hosting

# Self-Hosting

ZeroDrop's email worker is fully open source. Teams with strict compliance requirements can deploy their own instance.

## What you need

* A Cloudflare account with Workers enabled
* A domain added to Cloudflare (for Email Routing)
* An Upstash Redis database
* Node.js 18+ and Wrangler CLI

## Setup

```bash theme={null}
git clone https://github.com/zerodrop-dev/zerodrop-worker.git
cd zerodrop-worker
npm install
```

Set your secrets:

```bash theme={null}
npx wrangler secret put UPSTASH_REDIS_REST_URL
npx wrangler secret put UPSTASH_REDIS_REST_TOKEN
```

Deploy:

```bash theme={null}
npx wrangler deploy
```

Configure Cloudflare Email Routing to send all emails at `*@yourdomain.com` to your deployed worker.

## Point the SDK at your instance

```typescript theme={null}
const mail = new ZeroDrop(undefined, {
  baseUrl: 'https://your-dashboard.yourdomain.com'
});
```

## Full guide

See [SELF\_HOSTING.md](https://github.com/zerodrop-dev/zerodrop-worker/blob/master/SELF_HOSTING.md) in the worker repo for the complete setup guide including wrangler.toml configuration, disabling the AI spam filter, and cost estimates.

## Cost estimate

* **Cloudflare Workers** — free tier: 100,000 requests/day
* **Cloudflare Email Routing** — free
* **Cloudflare Workers AI** — free tier: 10,000 neurons/day
* **Upstash Redis** — free tier: 10,000 commands/day

For most CI pipelines, self-hosting runs entirely within free tiers.
