Perfect for solo devs — and the agents building with them. No credit card required.
What you get

FAQ
What is a log?
A log is the record of an event. A flat data structure with timestamp, level (debug, info, warning, error, critical), and a message. Although Logfire can receive logs, we recommend you use it to store high-value events from your application, such as spans and traces.
What is a span?
A span is the building block of a trace, represented by a single row in the Logfire live view. Spans have start and end times, attributes (key-value metadata), and can nest under parent spans. Multiple (nested) spans form a trace, represents a complete request flow or operation.
What is a metric?
A metric is a collection of datapoints at intervals. When stored with timestamps, metrics become timeseries. While traces show what happened in a request and logs capture single events, metrics show trends across your system.
What is a guest?
A guest is a read-only user that can be invited directly to a Logfire project, but not to an organization. Guests are similar to outside collaborators in GitHub.
What happens if I use more than the free allowance?
For all plans we'll send you emails and in-app alerts on your level of use. On Personal, if you go well over the free allowance, we'll eventually stop ingesting new data, and you might see warnings in stdout/stderr about 4XX responses from the Logfire API. For Team, Growth and Enterprise customers you'll be charged at the plan specific rate for your additional usage.
Can I use the Personal plan in production?
Yes! The Personal plan is designed for you to test Logfire or use it with side projects. You can safely use it in production if you accept that ingestion pauses once you hit the 10 million records per month cap — so you can't owe us anything on Personal.
What is the price cap?
We offer a spending cap to all paying customers. Once you hit your cap, new telemetry is hidden from view, but we keep capturing it up to a generous threshold. Raise your cap anytime to unlock your data, so you'll never lose visibility when you need it most. To set a spending cap, email us at accounts@pydantic.dev.
I'm currently on the Free tier. Will I have to pay from now on?
If you're the only user on an account with fewer than 3 projects and under 10 million logs/spans/metrics, nothing changes except your plan name (to Personal). Your usage is still free. If you exceed these limits or have additional users, you'll be asked to upgrade. If you don't upgrade, data ingestion will eventually be suspended and orgs other than your Personal account will be disabled.
I'm currently on the free tier and have exceeded the allowance of 10 million logs/span/metrics. Can I pay for the extra usage ad-hoc?
Ad-hoc payments for additional records are not available on the Personal plan. If your usage exceeds the 10 million record allowance, you'll need to upgrade your plan.
How long is my data stored in Logfire?
30 days on Personal and Team, up to 90 days on Growth. Enterprise customers can configure custom retention (unlimited available).
Will Pydantic remain free?
The Pydantic data validation library is (always has been, always will be) completely free and permissively licensed under the MIT license. Prices displayed on this page apply to Pydantic Logfire, only.
