Loopers
Firewall for the Agentic Era
Ever had an autonomous agent get stuck in a loop and burn your budget while you stepped away?
We built Loopers because we lived that exact nightmare. Loopers is the runtime security firewall and governance platform that gives your autonomous agents hard boundaries — before a single dollar is billed or a rogue tool executes.
The 3 things that go wrong when you build with agents
If you have built with Aider, Claude Code, LangGraph, or custom agent swarms, you have probably lived through at least one of these:
"I just wanted it to fix a bug"
You gave your agent a coding task and stepped out for coffee. The model hit a minor error, hallucinated a broken patch, failed again, and retried 50 times in an infinite reasoning loop. You only find out when OpenAI charges your card.
"I told it not to delete anything in AGENTS.md"
System prompts are polite requests, not security boundaries. As conversation context expands or the agent ingests messy third-party web content, it forgets directives and executes dangerous shell commands or leaks database secrets.
-32001 so the agent self-corrects without crashing."Great, a chart showing my money is already gone"
Traditional observability tools and gateways are passive recorders. They are like a security camera filming a burglary — they send a Slack notification after your budget is burned or data is exfiltrated.
Why Prompting and In-App Libraries Can't Protect You
You wouldn't secure a web server by asking user input to behave nicely. You put a firewall in front of it. Autonomous agents need the exact same network boundary.
Prompt Rules (AGENTS.md)
Probabilistic. Bypassed by jailbreaks, context truncation, or model hallucinations.
In-Process Python SDKs
Heavy dependencies, high latency, and easily circumvented if the host process crashes.
Observability Gateways
Purely reactive. Only logs disasters after your credit card has been charged.
Loopers
Out-of-process network proxy. Pre-call atomic budget leases. Mid-stream cutoff. Zero SDK changes.
Keep your agent code exactly as it is
Loopers is framework-agnostic. Route your traffic without installing SDKs or changing existing agent logic.
Wrap Any Local CLI Agent
Wrap tools like aider, claude, openhands, or gemini:
# Export proxy key & provider key
export LOOPERS_PROXY_KEY="lp-your-key"
export OPENAI_API_KEY="sk-actual-key"
# Run safely under Loopers
loopers exec -- aider
Works with Python, Node, Swarms
Point LangChain, CrewAI, AutoGen, or raw SDKs by updating one environment variable:
# Point client to Loopers proxy
export OPENAI_BASE_URL=\
"http://localhost:8080/lp-xxx/openai/v1"
export OPENAI_API_KEY="sk-actual-key"
# Run existing agent code
python run_agent.py
Choose how you want to run Loopers
Whether you are an individual developer protecting your personal API keys or an engineering organization governing multi-agent fleets in production, Loopers adapts to your infrastructure.
Loopers Open-Source Core
Ideal for solo builders, local CLI agents, and private single-tenant VPC deployments.
- 100% Free & MIT Licensed: Fully transparent, community-driven codebase.
- Pure Go Bare-Metal Engine: Sub-millisecond latency (<5ms) with zero data persistence.
- Pre-Call Atomic Leases: 0% budget over-charge guarantee via Redis Lua.
- Mid-Stream SSE Cutoff: Actively severs runaway loops and leaks mid-flight.
- Deploy in 30 Seconds: Single binary or lightweight Docker container.
Loopers Enterprise & Cloud
Designed for engineering organizations, multi-agent swarms, and enterprise security compliance.
- Centralized Fleet Hierarchy: 3-Tier control (Org → Projects → Agent Keys) with team RBAC.
- Live Management Console: Real-time spend velocity, agent trajectories, and anomaly tracking.
- Human-in-the-Loop JIT Triage: NATS-backed approval queues via Slack, Teams, or Webhooks.
- Honeypot Decoy Traps: Injects fake tools to catch prompt injections before damage happens.
- In-VPC & Air-Gapped Packaging: Helm charts, Kubernetes, SAML 2.0 / Okta SSO, and audit trails.
Ask Us for a 60-Second Live Demo
Since you just scanned our QR code, you're standing right in front of us! Look up and talk to Varad or Mayank—we can run a live terminal demo right now showing an agent loop getting severed in real time.
Things you can ask us right now at the booth:
- "Can you show me a live demo of Loopers killing an infinite agent loop in the terminal?"
- "How do we wrap our existing Aider / Claude / LangGraph agents without changing code?"
- "How does team-wide budget enforcement work for multiple developers?"
