Rive
Interactive vector animation
PaidAnimation & motionrive.app
What it is
Design tool plus lightweight runtime for interactive vector animation — the Lottie alternative. You build a state machine so the animation responds to inputs, export a tiny .riv file, and drive it from code.
Why it earns a slot
Only worth it if you have three or more animations to amortize the WASM and a designer to own the files. An unowned .riv is an opaque binary nobody can edit.
Know before you commit
Publishing moved behind a paywall in Oct 2025 — the free tier cannot export a .riv for production. And the runtime is 88 kB JS plus a 725 kB gzipped WASM binary (304 kB on canvas-lite), fetched from unpkg by default — self-host it and call RuntimeLoader.setWasmUrl().
