Best Self Hosted Alternatives to BlazeMeter

Bencher is a continuous benchmarking suite that helps teams detect and prevent performance regressions before they reach production. It combines a CLI that wraps existing benchmark harnesses with an API server and a web console for tracking and analysis.

Key Features

• CLI to run and upload benchmark results from local runs or CI pipelines
• Web console to monitor, query, and graph benchmark history by branch, testbed, benchmark, and measure
• Regression detection analytics to fail CI or alert when performance crosses defined thresholds
• REST API for automation and integrations
• Adapters for common benchmarking harnesses across multiple languages (e.g., Rust, Go, Java, Python, JavaScript, C#, C++)

Use Cases

• Add performance regression checks to CI/CD alongside unit tests
• Track long-term performance trends across branches, environments, and hardware testbeds
• Monitor non-runtime metrics like build time and binary/file size over time

Bencher is well-suited for engineering teams that want reproducible performance tracking and automated regression detection using their existing benchmark tools and workflows.
