24 alternatives to MechSim — Kinematics simulator
Simulate planar mechanisms in seconds. No install required
MechSim is a browser-based kinematic simulator that lets users design and analyze planar linkage mechanisms without installation. It uses a Newton-Raphson constraint solver to handle complex 2D motion, allowing… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Hi HN! Erik here from Pig.dev, and today I'd like to share a new project we've just open sourced: Muscle Mem is an SDK that records your agent's tool-calling patterns as it solves tasks, and will deterministically replay those learned trajectories whenever the task is encountered again, falling back to agent mode if edge cases are detected. Like a JIT compiler, for behaviors. At Pig, we built computer-use agents for automating legacy Windows applications (healthcare, lending, manufacturing, etc). A recurring theme we ran into was that businesses already had RPA (pure-software scripts), and…

Features include: - Several preset periodic orbits: the classic Figure-8, plus newly discovered 3D solutions from Li and Liao's recent database of 10,000+ orbits (https://arxiv.org/html/2508.08568v1) - Full 3D camera controls (rotate/pan/zoom) with body-following mode - Force and velocity vector visualization - Timeline scrubbing to explore the full orbital period The 3D presets are particularly interesting. Try "O₂(1.2)" or "Piano O₆(0.6)" from the Load Presets menu to see configurations where bodies weave in and out of the orbital plane. Most browser…

Hi HN, we are building SimBricks, an open-source simulation framework for heterogeneous systems, especially with custom hardware. SimBricks modularly combines existing simulators for machines, networks, and hardware, allowing you to build, test, and evaluate intricate complete systems in a virtual environment. Head over to the SimBricks website (https://simbricks.github.io/, also has a quick demo video) to learn more. We have pre-built docker images, and you can even immediately play around on codespaces. Concrete use-cases: - Evaluate HW accelerators, from early design with…

Long time reader, first time self-promoter. I'm a bicycle mechanic that figured I could make the process of bicycle wheelbuilding faster, more accurate and more satisfying. I do it by sampling digital indicators, rendering the data in useful ways, and injecting domain-specific insights. The UI interaction happens by foot pedal so my paradigm retains the traditional way of working with your hands.

I built a mechanical computer kit: https://whomtech.com/show-hn tl;dr: it's a cellular automaton on a "loom" of alternating bars, using contoured tiles to guide marbles through logic gates. It's not just "Turing complete, job done"; I've tried to make it actually practical. Devices are compact, e.g. you can fit a binary adder into a 3cm square. It took me nearly two years and dozens of different approaches. There's a sequence of interactive tutorials to try out, demo videos, and a janky simulator. I've also sent out a few prototype kits and have some more ready to go. Please…

VoxelChain is an experimental tool to create voxel worlds in the browser. The lighting is fully ray traced in real-time and there is powerful cellular-automata based programming system, which allows to create complex digital circuits and model the behaviour of voxels (behaviour such as falling sand or water). Technology wise, I'm using WebGL2 for the rendering and the simulation is coded in C89 and gets compiled to WebAssembly (with multi-threading) using Clang. The simulation is basically a custom cellular automaton and is fully parallelized. Once WebGPU is released, I'm planning to run the…
