AgentTap is an open-source observability tool that intercepts AI agent traffic at the network level using a split VPN and local MITM proxy. Instead of requiring you to add tracing SDKs to every agent, AgentTap sits in front of your network and captures all calls to OpenAI, Anthropic, Cohere, and other LLM providers automatically — with zero per-app configuration. The tool streams captured traces in real time, reconstructing the full prompt-response pairs, tool calls, and token counts from raw network traffic. You can observe agents running in any language, any framework, or any black-box binary — even commercial tools you don't control the source of. It's the network packet analyzer equivalent for AI agents. Built in TypeScript with a Rust-based VPN core, AgentTap is currently at 3 stars and very early — but the architectural approach is genuinely novel. Existing tools like LangSmith, Helicone, and Braintrust all require explicit SDK integration. AgentTap's bet is that the right observability layer is the network, not the application.

Scale AI Evaluation Suite for Agentic AI

Standardized benchmarks for multi-step agentic AI systems

Entry

Scale AI's Evaluation Suite provides standardized benchmarks and human-validated test sets specifically designed for evaluating multi-step agentic AI systems. It surfaces where agents fail across complex, multi-turn workflows through a structured API available to enterprise customers. The suite fills a genuine gap: most existing evals were designed for single-turn LLM responses, not agents that take sequences of actions across tools and contexts.

Treating agent observability as a network problem is a genuinely smart idea. Being able to observe any LLM calls — including from tools you didn't write — is a superpower for debugging multi-agent systems. Zero instrumentation overhead is huge.

The primitive here is clear: human-validated, multi-step task scaffolding that gives you ground-truth labels for agentic failure modes — not just 'did it answer correctly' but 'did it take the right sequence of actions without derailing.' That's a real problem. Single-turn evals like MMLU tell you nothing about whether your agent will loop indefinitely on a tool-call error or hallucinate a subtask completion. The DX bet is API-first access to curated test sets, which is the right call — nobody wants to wrangle eval pipelines through a dashboard. My concern is the classic enterprise gate: 'contact sales' before you can touch anything means the first 10 minutes aren't a developer experience at all, they're a sales cycle. If they open a self-serve tier with even a constrained benchmark set, this becomes essential infrastructure. Right now it's a strong idea with a locked door.

Running a MITM proxy through all your LLM traffic is a serious security commitment — you're decrypting TLS in-process. In corporate environments this will fail security reviews immediately. Also, 3 stars and created two days ago. Give it six months.

The direct competitors here are HELM, AgentBench, and whatever evaluation harnesses OpenAI and Anthropic are quietly building into their own platforms — and Scale's actual advantage is the human-labeling infrastructure they've had for a decade. That's not nothing. The scenario where this breaks is any team not already deep in the Scale ecosystem: the enterprise-only pricing means the researchers and indie teams who actually publish eval papers won't use this, which means community validation won't come, which means the benchmarks risk being Scale's proprietary opinion about what 'good' looks like. What kills this in 12 months: model providers ship native agentic eval tooling as a free tier feature, and Scale's moat collapses to 'we have more expensive human raters.' For this to hold, Scale needs to publish the methodology openly and let the community stress-test it — otherwise it's a benchmark designed by the tool's author, which is exactly what I'm tired of.

Futurist

As agents become black boxes running across systems we don't control, network-level observability becomes the only viable audit layer. AgentTap is pioneering the right approach — what Wireshark did for networks, this could do for AI infrastructure.

The thesis here is specific and falsifiable: by 2027, enterprises deploying agentic systems will face regulatory and liability pressure to demonstrate measurable, auditable performance on multi-step task completion — and whoever owns the benchmark standard owns the compliance conversation. Scale is betting that evals become a procurement requirement, not just a dev-team nicety. That bet depends on two things going right: enterprise AI deployments actually hitting meaningful failure rates that surface in production (they will), and no open-source consortium standardizing agentic benchmarks before Scale's suite becomes the default reference (less certain). The second-order effect if this wins is significant — Scale becomes the ratings agency for AI agents, which is a power position nobody else currently holds. The trend line is the shift from LLM evals to agent evals, and Scale is early on the productized side of it, even if academia has been discussing it for 18 months. The future state where this is infrastructure: every enterprise AI procurement RFP requires a Scale Evaluation Suite score.

This is squarely a backend DevOps tool and the setup complexity (VPN + proxy + certs) puts it out of reach for most creative practitioners. Cool concept but the audience is very narrow.

The buyer here is the enterprise AI team that already has a Scale contract — this is an expansion product, not a wedge. That's a legitimate land-and-expand play, but the expand story only works if the buyer has both an agentic deployment and a budget line for evaluation infrastructure, which is a narrower Venn diagram than it looks. The moat question is the real issue: Scale's defensibility is human labeling quality and dataset curation, but the moment Google DeepMind or Anthropic decides to open-source a rigorous agentic benchmark suite — which costs them almost nothing to do — Scale's pricing leverage evaporates. 'Contact sales' pricing for an eval product also signals they haven't found the right price point yet, which is a tell. The business survives if Scale can turn benchmark scores into a certification or compliance artifact that enterprises need for insurance or regulation — that's the pricing power scenario. Without that, this is a premium feature for existing customers, not a standalone business.
