The Lottie render API

POST a Lottie or dotLottie, get back a GIF, MP4, WebM, APNG, PNG sequence, or SVG. Built for CI/CD, CMSs, and pipelines — the server-side conversion nobody else offers Lottie-native.

Free tier planned: 100 renders/month. Paid from $19/mo.

The endpoint exists today and returns the documented contract with HTTP 501 — it goes live for beta users first. Tell us your use case when you join; it directly shapes what ships.

CI/CD-first

Generate previews, social videos, and email GIFs in your pipeline — npm package and GitHub Action planned.

Lottie-native

Real Lottie rendering (dotlottie-rs), not a generic file converter — deterministic frames, alpha, dotLottie in.

Usage-priced

Pay per render, not per seat. Free 100/mo, then $19/5k · $49/25k · $149/100k with metered overage.

Sound like your pipeline?

Beta users get free renders during the beta and directly shape the contract, formats, and pricing tiers.
