Platform
From first event to production dashboard
Start with the data you already have. Add structure only when it earns its keep.
Query
Use SQL when the question gets interesting
Move from point-and-click exploration to full ClickHouse SQL without exporting anything. Write joins, window functions, funnels, and cohort queries, then chart the results in the same notebook.

Monitor
Turn analysis into something people use
Compose live dashboards, alert on important changes, and securely embed customer-facing analytics. One event stream can serve your team, your users, and your operations.
Scale
Pricing you can model before you grow
Start free, then pay a published rate based on stored event volume. Retention controls help you keep the data that matters and remove the data that does not.
Stored events
2,000,608
Published rate
$12 / million
Connect
Connect the systems already producing events
Use one-click integrations for Vercel, Segment, and Stripe, or send a plain HTTP request from any language. No SDK is required.
POST api.graphjson.com/api/log{ "collection": "payments", … }
Capabilities
A focused analytics toolkit
The core pieces you need to collect events, investigate behavior, and share what you learn.
Fast by design
Columnar storage and purpose-built queries keep interactive analysis responsive as your event history grows.
Alerts
Watch important metrics and get notified when a value crosses the threshold you define.
Plain HTTP API
Send JSON from any language with a generated request snippet. There is no client library to install or keep updated.
ClickHouse SQL
Run joins, window functions, and custom aggregations directly over your events, then visualize the result.
Dashboards
Arrange the charts your team needs in a drag-and-drop workspace, without rebuilding every query in frontend code.
Collections
Separate event streams by product, environment, team, or retention policy while keeping one consistent analysis workflow.
Controlled access
Keep API keys on the server, separate data by collection, and choose retention windows that fit each workload.
Available in real time
New events become explorable as they arrive, so dashboards and investigations are based on what is happening now.
From customers
Trusted by builders shipping real products

I really love the simplicity of @GraphJSON. You just push the all your data to it and you would be able to make all sorts of graphs and visualizations out of that data.
