velixir Documentation

velixir is a European cloud platform for deploying high-scale web apps in any language. Send it your source and velixir builds it server-side into a container image, then runs it with autoscaling, zero-downtime rolling deploys, instant rollback, and high availability. Node.js, Python, Go, Ruby, PHP, Java, Elixir, Rust, .NET, Deno, and F# are all first-class, with no Dockerfile, no build config, and no local build step. Managed Postgres and Valkey are included.

velixir is a European cloud with EU data residency. Everything runs in EU Central, inside the European Union, so your data stays in the EU.

These docs cover the platform from first sign-up through production deploys. If you're API-shopping, the API reference is the place to start.

Start here

  • Sign up and deploy - Account creation and your first deploy in about five minutes.
  • Install the CLI - velixir is the canonical way to ship code. Available for Windows, macOS, and Linux.
  • Templates - Deploy a ready-to-run app, database included, in one step.
  • Deploying - velixir deploy, GitHub Actions, and the dashboard source upload.

Apps

  • Environment variables - Set per-app config, including secrets that get encrypted at rest.
  • Scaling and HA - Plans, autoscaling, deployment slots, and warm standby replicas.
  • Custom domains - Point your domain at an app and get TLS issued automatically.
  • Security - Web application firewall, per-IP rate limits, and under attack mode.

Managed services

  • Postgres databases - Managed PostgreSQL per project, with point-in-time recovery and optional high availability.
  • Valkey caches - Drop-in Redis replacement, also fully managed.

Team

  • Invites and roles - Bring teammates in as Owner, Admin, or Member, with per-project and per-app access.
  • Billing - How charges work, credit, top-ups, and what happens when credit runs out.

Reference

  • Limits and fair use - What each plan allows, outbound network rules, and how to request a raise.
  • API keys - Keys for the CLI, CI, and your own scripts.
