/ ABOUT OPENC3

Built by the team that built COSMOS.

Two decades of command-and-control, distilled into a product engineers actually want to use. OpenC3 exists to put COSMOS in the hands of every builder shipping hardware that matters.

/ ORIGIN STORY

From a payload bench in 2004 to a 50-mission console.

2004

COSMOS is born

Ryan Melton and Jason Thomas write the first version inside Ball Aerospace to control a payload during integration. It never stops growing.

2014

Open-sourced

Ball releases COSMOS as open-source. It spreads across the industry as the de facto hardware console for satellite I&T.

2022

OpenC3 founded

Ryan and Jason spin out OpenC3 to give COSMOS a dedicated home — full-time engineering, modern packaging, and a commercial path.

2023

Enterprise launches

COSMOS Enterprise ships: clustering, multi-user, SSO, encryption, and 24/7 support. The same Core engine, hardened for production.

2026

v7.2 — and counting

50+ missions, every major bus and ground-station vendor supported, TRL-9 across the board. Still shipping every quarter.

/ WHAT WE BELIEVE

The principles behind the product.

Hardware independence

If it talks, we talk to it. No vendor lock-in. No preferred bus.

Low barrier to entry

Core is free. Docs are public. You can be doing useful work today.

Ease of use

Text-based configuration. Ruby & Python scripting.

Openness

Open-source Core under the OpenC3 Builder's License. Open APIs everywhere.

Value

No seat counts. No node limits. Cost reflects outcome, not friction.

Continuous innovation

We ship constantly. Every customer benefits from every release.
