What it does
BenchSpan is a benchmarking platform for AI agents. Running benchmarks is slow, expensive, and fragile. We fix that. Onboard your agent once (we onboarded Claude Code in 37 lines), run any benchmark in parallel in the cloud, and get every result in one place your whole team can see. When runs fail halfway, rerun just what broke. Compare runs side by side to see exactly where your agent is improving. Stop fighting your benchmarks and start shipping your agent.
Block prompt injection, data exfiltration, and unauthorized tool access before they reach your AI agents. Benchspan monitors production agent traffic, trains a custom security model on your data, and generates compliance evidence automatically. Backed by Y Combinator.
The most advanced detection available today . Built for the agent era. Paste any text. Pick a role. Get the same verdict your production agent would see. No signup. Every commercial PI detector was trained on direct user-to-chatbot attacks. Agents don't get hit that way. They get hit by instructions hidden inside emails, documents, tool responses, and web pages — indirect prompt injection. We trained Benchspan on those attacks from day one. Indirect prompt injection via tool outputs. Next best commercial detector catches 71%. Attacks hidden in structured API data. AWS Bedrock catches 0%. Meta Prompt Guard 2 catches 2%. Full methodology, per-sample predictions, and raw numbers available on…from benchspan.com

Coarena by CoastyAug 2026 · coarena.ai · ▲111We built a computer use agent once and got it benchmarked at the 2nd position in the biggest benchmark for this field but in the process, we realized one thing, how outdated and inefficient these benchmarks are and how they don't truly capture how these tasks went. So we thought a community led benchmarking arena would be the way to go about. https://coarena.ai/. You just have to put in a task and two side by side windows with hidden models will show up and do the same task and at the end you vote which one did better(or none). We have a leaderboard where we rank all the…
BenchFlow – run AI benchmarks as an API2025 · github.com · ▲24I built BenchFlow, an open-source framework that lets you integrate and evaluate AI tasks using Docker-based benchmarks. You can try it out right now by cloning the repo and running a benchmark in minutes. As an AI researcher, I was frustrated with how much time my team spent setting up benchmark environments rather than actually improving our models. We'd spend weeks configuring environments, only to find inconsistencies when comparing results with other teams. BenchFlow started as an internal tool to standardize our evaluation process, and we decided to open-source it after seeing how much…
