OpenRocket designs and simulates model rockets using configurable components, motors, and flight conditions. It helps hobbyists compare stability and predicted trajectories before construction, while real-world material choices, assembly quality, weather, and flight rules remain separate considerations.

Enter measured component masses and dimensions rather than relying on idealized estimates. Compare stability and trajectory across plausible motors and wind conditions, then update the model after construction. Treat predicted results as one planning input and follow the applicable launch procedures and site requirements when preparing an actual flight.
This is best suited to model rocketry enthusiasts evaluating designs. Before committing a larger project, account for these trade-offs: predictions depend on accurate inputs; does not replace real-world safety procedures.
A few things you might be wondering.
Is OpenRocket free?
The GPL software is available without a license subscription and includes Rocket component design and Stability estimates. This covers the downloadable application, while optional support, third-party services, and separately licensed materials have their own terms.
Can OpenRocket compare different motors?
Yes. Motor selection is part of the flight-simulation workflow.
Do simulated flight results guarantee actual performance?
No. Construction, inputs, weather, and other real conditions affect flight.
Where can I check the latest prices?
Use the provider link on this page. Billing period, location, team size, promotions, taxes, and optional extras may affect the amount you pay.
How should I compare this tool with alternatives?
Choose tools for the same task, then compare their feature limits, platform support, and total cost for your team. The Compare button helps you keep a shortlist.
Are the user reviews moderated?
Yes. New reviews are submitted for moderation. We show published user reviews separately from the editorial overview and never assign a default user rating.
