flamegraph.com is an online flame graph tool created by Grafana Labs, focused on “Upload and Share Interactive Flamegraphs.” Users can upload performance profiles and generate publicly shareable links. The site also provides a Single View example for inspecting an individual profile, as well as a Diff View example for comparing two profiles.
Based on the page content, it supports three profile formats: pprof, json, and collapsed. Files can be uploaded via drag-and-drop or file selection. Its focus is very clear: first, visualizing profiles as interactive flame graphs to help identify hot call stacks; second, using diff view to compare two profiles, which is useful for analyzing performance differences before and after optimization or between versions. The page mentions Grafana Pyroscope and is labeled as created by Grafana Labs, indicating some connection with Grafana’s observability and continuous profiling ecosystem.
The captured content does not disclose pricing, paid plans, payment methods, account systems, or usage limits. It also does not state whether an API/SDK is available. Self-hosting options and open-source status are likewise not mentioned in the main content. Therefore, it is best understood as a quick web-based tool for viewing and sharing profiles, rather than something that can be judged from the page alone as suitable for enterprise private deployment or automated pipeline integration.
The main advantages are its short onboarding path—upload a file to view and share it—support for common profile formats, and availability of both single-profile viewing and diff comparison, covering frequent needs in performance analysis. The main drawback is limited disclosure: the page does not explain access control for public share links, data retention, privacy policy details, upload size limits, or team collaboration features. For profiles that include internal function names, file paths, or business logic, users should evaluate the risks carefully before uploading.
It is suitable for developers, SREs, and performance engineers troubleshooting CPU hotspots, sharing performance reports, or comparing optimization results. The page does not provide enough information to assess access from China, so it should be marked as unknown. If access to Grafana-related services is unstable, alternatives such as Speedscope, Brendan Gregg FlameGraph, Parca, or a local pprof Web UI may be worth considering.
