Build it on screen.
Explore its flight.

One workspace for shaping your rocket, seeing the assembled design and exploring what happens after launch.

  1. 01 / Design

    Make it your rocket.

    Choose a nose profile, body size, fins and colors. Rotate the model or separate its parts to see how they fit.

  2. 02 / Simulate

    Compare the possibilities.

    Add weight, balance and flight settings. Compare motors for supported designs with OpenRocket predictions.

  3. 03 / Build

    Take the design with you.

    Download your selected printable parts, assembly reference and build checklist. Save or share your editable design.

Watch the prediction
come to life.

Follow your rocket from the pad, switch cameras, and jump to burnout, apogee or parachute deployment. See altitude, speed and drift as you scrub through the flight.

Use measured weight and balance for your completed build. Simulation results are predictions, not flight validation.

Built by a rocketeer, for rocketeers

For the care you put into every build.

ITERA began with a simple goal: premium tools and displays worthy of the time and care serious rocketeers put into their rockets. That same idea now reaches from the workbench to Rocket Lab, print files and a growing plans library.
