ParamTune

ParamTune is a free, open source configuration hub for teams who want full control. Self-host it anywhere and manage platform schemas and versions through a fast UI and a simple, JSON-first API.

Everything you need

Everything you need to safely evolve configs across iOS, Android, Web, and more—without giving up ownership to a hosted service.

History & rollback

Versioned configs

Track every change to your configuration with immutable history and easy rollbacks per platform or environment.

Safe by design

Schema-first safety

Back your configs with JSON schemas, get instant validation, and catch breaking changes before they reach production.

Cross-platform

Multi-platform aware

Model iOS, Android, Web, backends, and more in one place with clear versions and environments for each.

Schema editor

Edit JSON schemas with focused tooling, history, and previews tailored for configuration work.

Live config history

Understand what changed, when, and for which platform with at-a-glance version history.

Simple HTTP APIs

Serve configuration and schemas over clean HTTP endpoints that are easy to consume from any client.

Dark, focused UI

A minimal, keyboard-friendly interface that gets out of the way so you can ship configuration changes faster.

Fast for power users

Keyboard-first flows, clear focus states, and carefully chosen defaults.

OSS & extensible

Open source and self-hosted by default so you can fork, extend, and integrate with your own stack.
