Pyroscope

Overview

Pyroscope is a continuous profiling tool for teams investigating CPU, memory and thread behavior across a range of programming languages. It suits engineering teams that need profiling across several runtimes and can work within defined ingestion and retention limits.

Its free tier makes it possible to start without a subscription, while Pro adds a longer retention window for a monthly platform fee plus usage charges. The choice hinges on how much profile data you ingest and how long you need to keep it.

Key features

• CPU, memory and thread profiling: Pyroscope covers three useful dimensions of application behavior, making it a fit for teams that need more than CPU profiles alone.
• Broad language coverage: It supports C/C++, Go, Rust, Zig, Java, .NET, Python, Ruby, PHP, Node.js and Perl. That breadth can serve polyglot environments without requiring a different profiler for every listed language.
• Two profiling modes: Both modes are supported, though the specific modes are not identified here, so this alone is not enough to judge fit for a particular workflow.

Pricing

Pyroscope uses a freemium model, with Free, Pro and Enterprise options. The free plan costs nothing, is billed Always free, and includes 50 GB ingested per month with 14-day retention. It is a sensible starting point for teams that can stay within that cap and do not need to keep profiles longer.

Pro costs $19 a month, billed as a $19 per month platform fee, with additional usage billed separately. It also includes 50 GB ingested per month, but extends retention to 30 days. That makes Pro relevant when a longer lookback matters, though the separate usage billing means the platform fee is not the whole cost. The same ingestion cap appears on both Free and Pro.

Enterprise has custom pricing and a minimum commit of $25,000 per year. That is a substantial commitment, so it is suited to organizations prepared for an enterprise-scale agreement rather than teams simply seeking a modest step up from Pro.

Platforms

Pyroscope is available for Linux, macOS, Windows and the web. This span supports teams working across common desktop and server environments, though it does not establish support for mobile platforms.

Who it's for

Pyroscope is a strong candidate for teams working across several supported languages that want CPU, memory and thread profiling in one tool. Free fits evaluation or lower-volume use with a 14-day retention window; Pro fits teams that need 30 days and accept separately billed usage. It is less compelling for teams that need more than 50 GB of monthly ingestion on the stated Free or Pro plans, or for buyers who need a predictable all-in Pro price.

Pros and cons

• Pro: CPU, memory and thread profiling cover multiple investigation needs.
• Pro: Eleven supported languages make it relevant to mixed-language environments.
• Pro: The always-free tier includes 50 GB of monthly ingestion, which offers room to begin without a subscription.
• Con: Free retention is limited to 14 days, which may be too short for slower investigations or comparisons over time.
• Con: Pro keeps the same 50 GB monthly ingestion allowance and bills additional usage separately, so longer retention does not raise the included cap.
• Con: Enterprise requires a $25,000 annual minimum commit, putting it beyond many smaller teams.

Alternatives

Google Cloud Profiler is worth considering for readers who want a free profiler with 30-day profile retention; quotas and limits apply. Choose Pyroscope instead when the stated CPU, memory and thread profiling coverage and its broader language list suit the need.

Metoro Kubernetes Profiling may fit readers prioritizing a free plan with 1 cluster, 1 user, 2 nodes and 28-day retention, or a Scale plan priced at $20 USD per node per month. Pyroscope is a different fit for teams seeking its listed multi-language coverage and profiling dimensions.

Sentry Continuous Profiling is another freemium option, with support across Android, iOS, desktop, web and other listed platforms.

Blackfire.io may suit readers looking for its Development plan at €33.25/month billed yearly, available yearly only, with 1 user and 1 Sandbox environment.

OpenTelemetry eBPF Profiler is a free alternative for Linux and self-hosted use.

Middleware is a freemium alternative with support across mobile, desktop and web platforms.

Coroot is another freemium choice, including a self-hosted Community Edition under Apache 2.0.

FusionReactor is a paid option with a free trial and a Developer License priced from $22 per month for development and test environments.

Verdict

Choose Pyroscope if your team needs CPU, memory and thread profiling across several of its supported languages, and the 50 GB monthly ingestion allowance fits your workload. Its always-free plan is a low-commitment starting point, and Pro buys a 30-day retention window; look elsewhere if you need a higher stated ingestion allowance, or a Pro price that includes usage.
