Sigmabench: the real-world benchmark for coding agents. Model-only benchmarks don't reflect real-world engineering environments. We measure coding agent performance on pull requests spanning many languages, architectures and repository sizes. Real-world agent performance varies widely between projects. Therefore, there is no universal “best agent.” There is only the best agent for your codebase. Sigmabench provides trusted, neutral evaluations of: - Open source projects to produce our publicly available leaderboard - Private evaluations for engineering teams to determine the best coding agents for their codebases - Private evaluations for vendors creating and optimizing coding agents Our mission is to equip our industry with a reliable way to evaluate, compare, and select the best coding agents for real-world software development, enabling companies to make transparent, evidence-backed decisions tailored to their unique environments.
