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.

Grass is a cloud-hosted VM service purpose-built for AI coding agents — specifically designed for the workflow where Claude Code, OpenCode, or similar tools run autonomously for hours at a time. Instead of tying up your local machine, you point your agent at a Grass VM: a standardized environment (built on Daytona) with isolated storage, git, and tooling. You then monitor and steer from any device, including your phone. The core problem Grass solves is familiar to anyone who's run long Claude Code sessions: your laptop fans spin up, terminal sessions die if you close the lid, and you can't easily check progress from a meeting. Grass decouples the agent execution environment from your local machine entirely. You launch a session, the agent works in the cloud, you check in on your phone when you want, push when you're done. Launching today on Product Hunt, Grass offers 10 free hours on signup with no credit card required — low friction enough to test before committing. The focus on coding agent infrastructure (rather than general cloud dev environments like Gitpod or GitHub Codespaces) reflects the specific demands of multi-hour agentic sessions: persistent state, mobile monitoring, and environment isolation. This is what remote development environments look like in the agent era.
Reviewer scorecard
“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.”
“This is exactly the right product for the agentic coding moment — Cursor 3 and Claude Code sessions can run for hours, and nobody wants their laptop locked up for that. Daytona as the underlying environment layer is a solid choice for reproducibility. The mobile monitoring interface is the feature I'd actually use most — steering from your phone mid-session is genuinely different from being tied to a terminal.”
“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.”
“GitHub Codespaces, Gitpod, and Daytona itself all solve the 'cloud dev environment' part of this. The 'optimized for AI agents' positioning may be thin differentiation — most of the pain is in the LLM costs, not the environment runtime. And handing a running agent shell access to a cloud VM raises the same blast-radius concerns that make local agent runs risky.”
“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.”
“Grass is betting that agentic coding becomes a background process you manage, not an interactive session you drive. That's the right bet. When Claude Code agents run 24/7 on cloud infrastructure across hundreds of tasks in parallel, the tooling for managing those runs — monitoring, steering, pushing — becomes critical developer infrastructure. Grass is building that early.”
“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.”
“For non-developers using Claude Code for automation and content projects, having it run somewhere other than my laptop is a huge quality-of-life improvement. I've had too many sessions fail because my laptop slept. The mobile monitoring means I can kick off a big content generation run, leave my desk, and check back on my phone like it's a bread machine.”
