No description of Data Protocol yet.
AgentShield is a cost observability platform for AI agents. Teams deploy LangChain, CrewAI, AutoGen, and LlamaIndex agents in production with zero visibility on what they actually cost. One agent loops overnight and a $1.50/day baseline becomes $150 before anyone notices. AgentShield fixes this...

As answered by people managing Data Protocol and AgentShield.one.
AgentShield.one's answer:
Built by a solo founder as part of a challenge to ship 6 SaaS products in 6 months. AgentShield is tool number 1. The idea came from watching developers in the build-in-public community share stories about AI agents looping overnight and generating unexpected bills. The entire product was built in 5 days across 7 sprints with public kill criteria: less than $200 MRR at 12 weeks means killing the product and moving on.
AgentShield.one's answer:
LangSmith and Langfuse focus on tracing and prompt engineering. Helicone focuses on API logging. AgentShield is the only tool that combines real-time cost monitoring with anomaly detection, session replay, and production guardrails like PII redaction and budget caps with kill switch. It also supports LangChain, CrewAI, AutoGen, and LlamaIndex out of the box with a single Python decorator.
AgentShield.one's answer:
AgentShield combines cost tracking, session replay, and guardrails in one platform specifically built for AI agents. Most observability tools focus on infrastructure metrics, not per-agent cost breakdowns. AgentShield lets you see exactly what each agent costs per task, replay every step of a session for debugging, and set budget caps with an automatic kill switch. Setup takes one line of code.
AgentShield.one's answer:
Teams and solo developers running AI agents in production who need visibility on costs and behavior. This includes startups with 3-30 developers deploying LLM-based agents, AI agencies managing agents for multiple clients, and indie hackers building AI products who want to avoid surprise API bills.
AgentShield.one's answer:
FastAPI, Next.js, Supabase, Redis, Celery, Stripe, Python SDK. Deployed on Railway, Vercel, and Cloudflare. Built with Claude Code.
