Tracking — entry 003 of 9
Pixela
Pixela is a single-developer, open-source habit- and effort-tracking service: every action goes through its REST API, turning daily counts, weight logs, or commit streaks into a GitHub-contribution-style graph. Callers register with a self-chosen token via `/v1/users`, then post daily values that render back as an embeddable SVG graph or badge — no dashboard beyond the API itself. Nearly every feature is free; a handful of extras (logo placement, priority support) are reserved for Patreon backers.

- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Stored keyNo key stored
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
