Choose the best plan for your needs

We don't provide a free trial. If you want to see Blackfire's potential, you can use our demo environment that shows all the available features at https://demo.blackfire.io/.

If you want to use your data with Blackfire, you can subscribe for a month of our Production plan and enjoy the profiling and monitoring experience.

Yes! We are thrilled to partner with GitHub Education and offer a free Profiler subscription via the GitHub Student Developer Pack to eligible students, schools and universities.

Blackfire Monitoring is currently available only to Production subscribers. It is priced per Traces Quota. It starts at 1 million traces per month and increments per million traces per month.

One trace is one PHP request which has been monitored by Blackfire. You can configure a sample rate, from 0% to 100%, to determine how many requests you would like to monitor. That sample rate can be configured separately for each environment. You can change that sample rate as many times as you need to control your quota consumption.

Such subscriptions can be billed only monthly and will sunset when the Monitoring features reach general availability. They will be replaced by a new subscription model.

Blackfire Monitoring offers an 8 weeks retention period.

The PHP probe gathers cost information about HTTP queries made through cURL. HTTP calls made through file_get_contents() are handled when using Guzzle orBuzz. More extensive support is coming soon. To prevent any leak of confidential data, URL parameters are removed before they ever hit blackfire.io's servers. The probe also gathers the number of bytes that go in and out of the PHP stream layer or cURL extension. This includes e.g. all network calls made using the socket or stream API (file_get_content, fgets...), the curl extension, or the mysqlnd driver.

The PHP probe gathers cost information about any SQL queries made using the PDO abstraction layer. Other drivers (mysql, mysqli, pgsql, oci8) are supported, too. To prevent any leak of confidential data, SQL parameters are removed before they ever hit blackfire.io's servers.

The timeline visualization shows individual function calls in a time-oriented way.

Environments allow you to give profiling access to a group of people on the same app, server, or cluster of servers.

There are many options to configure environments, depending on your needs, workflows, and current tooling.

Blackfire provides a way to define performance assertions in a.blackfire.yaml file that you store alongside your code. Assertions allow configuring absolute and relative thresholds to determine if a profile meets your performance criteria.

Blackfire supports profiling micro-services out-of-the-box. The Distributed Profiling feature enables to profile an HTTP request and propagate profiling to all sub-requests served by a PHP server on which Blackfire is installed.

Any time you profile your code, Blackfire detects issues according to best practices defined by our performance experts. Resolution recommendations are shown on each corresponding profile, and are fully documented so that you can understand exactly why we recommend such a best practice, how to fix the issue, and how to add a non-regression test in your .blackfire.yaml.

Build reports are the result of running scenarios; they are environment-specific, they need to be defined on the Blackfire.io Environment page. Builds can be started periodically, using the API or one of the integrations (Platform.sh...).

Notification Channels are used whenever a scenario is completed and a report is available; as they are environment-specific, they need to be defined on the Blackfire.io Environment page. Notification Channels are webhooks, e-mails, or native integrations with third party services (such as GitHub, Slack, ...).

For regular usages, you should never hit our generous 1,000 profiles per day per user.

For regular usages, you should never hit our generous 350 builds per day per user.

Blackfire can be used to profile code anywhere: development, test, staging, or production.
