Prelay is a self-hostable, end-to-end encrypted notification relay. Send a notification from any script, CI job, or app — and have it land on your phone, readable only by you.
▸Your app sends one HTTP request
The simplicity of a webhook. The privacy of end-to-end encryption.
Contents are encrypted before leaving the trusted boundary and decrypted only on your device. The relay never sees plaintext.
curl, bash, Python, CI, monitoring — anything that speaks HTTP can send. No SDK required to start.
Run your own relay in minutes with Docker. Own the infrastructure, the data, and the policy.
Use Prelay Cloud and the server still can't read your notifications. Privacy isn't a paid tier — it's the default.
No message history, no analytics, no profiling. Delivery records expire. Minimal data by design.
Deployments, backups, uptime alerts, home automation, scripts. One relay for everything that pings you.
No SDKs to learn. No vendor lock-in. One request in, one notification out.
curl -X POST https://prelay.example.com/v1/notify \

-d '{
"title": "Deployment failed",
"message": "Production deployment failed.",
"priority": "high"
}'# encrypted locally — the server never sees the contents
prelay send --encrypted --device phone \
--title "Backup complete" \
--message "Nightly backup finished at 03:00"Install the app, point it at your server, and a keypair is generated on-device. The private key never leaves.
Any HTTP client posts a notification. The relay encrypts it to your device's public key (or your tool encrypts first).
The app decrypts locally and shows the notification. The push network — and anyone in between — sees only ciphertext.
Same core, same protocol, same app. Pick where it runs.
Open source and free, forever. Run it on a VPS, a NAS, or your homelab with Docker.
Zero maintenance. Zero knowledge. The cloud server cannot read your notifications either.
