Store, query and plot data from your ESP32, Pi, or agent.

Create a project, get a write token, POST JSON. No signup, no keys to manage, no limits. Claim it with an email later if you want to keep it.

Projects are public and expire after 7 days unless claimed.

One HTTPS call

POST a flat JSON object, or an array of them. Any scalar keys you like — the schema is discovered for you.

Batched writes

Writes are coalesced into 100ms windows before they hit storage, so a busy sensor costs a fraction of a write.

Plot instantly

Every project gets a live chart. Data shows up within a second of the POST.
