Mekka

Mekka Design

The open-source design environment for mechatronic systems.

Compose parts into mechanisms with typed interfaces. Promote mates to joints. Export real engineering artefacts — STEP, URDF, BOM, STL. All offline, all free.

Status · Coming soon

Mekka Design is in pre-alpha. The capability list below is the spec; status badges call out what's already built. Drop your email and we'll let you know when the alpha is ready to install.

Five capability surfaces

Parts

shipped

Author parts via Python build functions executed in a bundled CAD kernel, or describe a part in natural language and refine through parameters. Drop them into the catalogue.

Assembly

shipped

Compose parts into mechanisms with five mate kinds. Promote mates to joints when motion is needed. Scrub joints to preview kinematic behaviour.

Controls

in-progress

Define control topology + trajectories on top of the assembly. Coming as part of M2.

Sim

planned

Embedded physics for design-loop verification. External-simulator export (URDF/MJCF) ships today; in-app sim lands with M3.

CAM

planned

Toolpath authoring for parts you fabricate yourself. Drives your CNC, your 3D printer, your laser.

Real engineering output

Every design exports to formats the rest of the world reads.

STEP

AP242 assembly + per-part files for the shop floor

URDF

Robot description with link/joint topology + meshes

BOM

CSV bill of materials with masses + quantities

STL

Tessellated meshes for 3D printing

glTF

Web-ready preview meshes

Part JSON

Round-trip-able parametric part definition

Pricing

Free for individuals. Optional tiers for teams.

Mekka Design is open source and free for solo engineers, hobbyists, and students. Teams that need live collaboration, RBAC, and audit logs can upgrade.

Principles

Composition-first

Every machine is a graph of typed, composable modules.

Typed interfaces everywhere

Connections are declared, not inferred.

Explicit over magic

We don't auto-complete your design. The tool explains itself.
