Transparent pricing for AI teams

The risk-free way to get started with AI Observability and Agent Evals is Pydantic Logfire.

Every plan includes $20/mo in .

Start with this one!

Personal

Free, forever

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

What you get
  • Covers 10 million logs, spans, and metrics every month. Personal is hard-capped here — upgrade to Team for additional records.
  • Trace agent runs from prompt through tool calls — Pydantic AI, LangChain, OpenAI SDK, anything OTel-instrumented.
  • Supports all OTel SDKs — every service lands on one correlated timeline.
  • Kubernetes, hosts, databases, and more — logs and host metrics with pre-built dashboards.
  • Bring up to 3 provider credentials (no markup). Access built-in providers with a 5% markup fee (requires adding a credit card).
Scale
  • This is a lot of telemetry for a solo developer! Once you hit the limit, ingestion pauses — so you can't owe us anything on the personal tier.
  • One admin seat (you).
  • Organize your apps.
  • Query your traces, logs, and metrics for the last 30 days.
Support & compliance
  • Get help from the Pydantic community — Slack, GitHub Discussions, and Stack Overflow. No SLA; response times depend on the community.

Team

$49/mo

For small teams shipping their first production workloads.

What you get
  • Covers 10 million logs, spans, and metrics every month. Additional records are $2 per million, or set a hard price cap to lock in your bill.
  • No per-agent fees — trace every agent run and only pay for the telemetry (records) you send.
  • Supports all OTel SDKs — every service on one correlated timeline with service inventory, service maps, and more. No per-service fees.
  • Kubernetes, hosts, databases, and more — logs and host metrics with pre-built dashboards and alerts.
  • Evaluate your AI outputs for free — no per-score charges.
  • Add human review to any trace or eval run — for RLHF training or manual quality checks.
  • Bring up to 3 provider credentials (no markup). Access built-in providers with a 5% markup fee.
Scale
  • Admin or member seats for you & your core team. 5 seats included, $25/extra seat.
  • Organize your apps. Scope access per project.
  • Query your traces, logs, and metrics for the last 30 days.
Support & compliance
  • Unsure after your first month? We'll refund you. And if you get hit with an unexpectedly large bill in your first month because of a spike in volume, we'll refund that too.

Growth

$249/mo

For teams running production AI services core to their business.

What you get
  • Covers 10 million logs, spans, and metrics every month. Additional records are $2 per million, or set a hard price cap to lock in your bill.
  • No per-agent fees — trace every agent run and only pay for the telemetry (records) you send.
  • Supports all OTel SDKs — every service on one correlated timeline with service inventory, service maps, and more. No per-service fees.
  • Kubernetes, hosts, databases, and more — logs and host metrics with pre-built dashboards and alerts.
  • Evaluate your AI outputs for free — no per-score charges.
  • Add human review to any trace or eval run — for RLHF training or manual quality checks.
  • Unlimited BYO provider credentials (no markup). Access built-in providers with a 3% markup fee.
  • Try new Logfire capabilities before they ship broadly. Feedback shapes what lands and when.
Scale
  • No per-seat cost — add your whole team.
  • No cap on read-only viewers. Bring in stakeholders, clients, or your CTO.
  • No limits on services, environments, or experiments.
  • Query your traces, logs, and metrics for the last 90 days, vs 30 on lower tiers.
Support & compliance
  • Unsure after your first month? We'll refund you. And if you get hit with an unexpectedly large bill in your first month because of a spike in volume, we'll refund that too.
  • Faster response times when you need help.
  • Self-serve deletion of users and trace data.
  • Ready-to-sign agreement for healthcare compliance.

Enterprise

Custom

For organizations where observability has to pass security review.

What you get
  • Every Growth-tier capability comes standard with Enterprise, plus the below.
  • Define Service Level Objectives on your traces and metrics, with error budgets and burn-rate alerts. Includes LLM provider SLOs — measure SLIs (latency, error rate) on the upstream LLM providers your enterprise services depend on.
  • Policy-based redaction and blocking for sensitive data — PII, credentials, regulated content — before it reaches an LLM or lands in your logs. Requires Full AI Gateway access (add-on).
  • Volume-discounted rates negotiated against your usage commit.
  • Fully managed cloud, single-tenant infrastructure, or self-hosted on your own cluster.
  • Bring your identity provider — first-party integrations for the common IDPs and generic SAML for the rest.
  • Unlimited BYO keys and built-in LLM providers, with enhanced Data Loss Prevention support on the LLM traffic path. Available as add-on.
Scale
  • Add your whole organization, no per-seat cost.
  • No cap on services, environments, or business units.
  • Custom retention policies to meet your data and compliance requirements.
Support & compliance
  • Custom data processing agreements and HIPAA business associate agreements — negotiated to fit your legal team's requirements.
  • Dedicated support with SLA-backed response times.

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.
