Build on the ballistics engine.

Solve JSON in, trajectory out. Call the hosted API or embed the Rust/WASM core directly in your own product.

The same engine that powers every Strelok app.

No drift between platforms, no re-implementation. Send a JSON request with sensible defaults — Lite calls can pass just muzzle velocity, BC, bullet weight and zero — and get a full trajectory with stability and transonic zones back.

Everything you need to integrate.

Canonical Rust core

Point-mass RK4 solver at dt = 0.0005 s with G1/G7 tables, spin drift, Coriolis and aerodynamic jump.

Ship it anywhere

Compile to C FFI for desktop, WASM for the web, or call the hosted HTTP endpoint. Same numbers everywhere.

Pro solvers

Monte-Carlo weapon-effectiveness zones and zero-angle truing via binary search, exposed on entitlement-gated endpoints.

Proven parity

Six golden-file tests pin output to canonical .308 168gr DOPE — matched within 0.3 MOA, 4 fps and 0.1 mil.
