Agents you can eval.
Agents you can govern.
Agents you can trust.
Fluiq sits on every agent run. It blocks prompt attacks before the model executes, scores trajectories against your golden runs, serves repeated work from cache, and traces every step across LangGraph, CrewAI, ADK, and MCP. Two lines of Python.

Observability tools tell you what broke.
Fluiq helps you prevent it.
Most platforms stop at tracing. Fluiq adds a security layer, a caching layer, and a quality gate, so you catch problems before your users do.
Full trace visibility across every LLM call
Every token, latency, and cost attributed to the exact agent node that spent it. Streaming traces, cost anomaly alerts, and per-model breakdowns, without changing how you write code.
- Per-node token attribution
- p50 / p95 / p99 latency tracking
- Multi-agent runs render as real DAGs: fan-outs, joins, and loops across LangGraph, CrewAI, and Google ADK
- Real-time trace streaming

Block attacks before they reach your model
A full suite of server-side scanners runs on every request. It catches jailbreaks, PII and secret leaks, and attacks injected through your tools, knowledge base, and other agents, not just the user message. Patterns are maintained server-side and updated without SDK releases. Everything fails open, so a scanner error never breaks your app.
- PII & secrets: cards, SSNs, IBANs, emails, names, provider API keys, high-entropy tokens
- Prompt attacks: injection, jailbreak, and instruction-override patterns
- RAG poisoning & indirect injection: retrieved docs and tool outputs scanned across the trace tree
- Tool misuse: exfiltration through tool arguments, plus allowlist enforcement
- Multi-agent trust: cross-agent injection and trust-boundary escalation across the DAG
Stop paying for duplicate LLM calls
Fluiq analyses your actual trace history to find which prompts repeat, then provisions a dedicated cache instance for your account. Repeated calls are served from cache automatically.
- Server-side caching, zero infra to manage
- Profile built from your real traffic patterns
- Configurable TTL and model scope

By Metric
Gate responses that fail quality thresholds
LLM-as-judge runs server-side after each call. Set per-metric thresholds. Warn mode logs quality scores to the dashboard; block mode raises FluiqEvalError before the response reaches your app. And for agents, agentic evaluation judges the whole run, not just single answers.
- hallucination, faithfulness, relevance, toxicity
- Agentic eval scores tool selection, trajectory-vs-goal, and multi-agent coordination across the run's DAG
- Borderline verdicts convene a multi-model judge jury; every member's score and reasoning is kept for audit
- Block mode prevents bad responses reaching users
Regression-test agents on real trajectories
Curate golden datasets straight from production traffic. Adding a run pins its entire trajectory (every agent step, tool call, and MCP call), so it stays evaluable forever, independent of trace retention. Then re-run agentic evaluation or the security suite over the whole set before you ship a prompt or model change.
- One click pins a whole run: steps, tools, MCP calls, and media
- Connect Agents imports every run an agent has made, and keeps auto-appending future ones
- Batch agentic-eval and security runs produce a scored regression report
- Examples carry live eval, security, and cost signals from their source runs

Write, version, and deploy prompts like software
A dedicated IDE-style editor for your prompt templates, with {{variable}} injection, full version history, and per-environment deployment. Iterate directly on real production traces, compare model outputs side-by-side, and ship with confidence.
- {{variable}} template syntax: define slots, fill at runtime via SDK
- Version history: save, browse, and restore any past version instantly
- One-click deployment to dev, staging, and production environments
- Side-by-side model comparison with the same prompt across models
- Pull directly from live traces and iterate on real-world prompts
How it works
Four functions. Production-ready in minutes.
01
fluiq.instrument()
Patches every LLM call automatically. Traces, costs, and latency start flowing to your dashboard.
02
fluiq.secure()
Pre-call attack detection blocks bad prompts. Post-call scanning redacts PII from stored traces.
03
fluiq.optimize()
Fluiq analyses your trace history, provisions Fluiq Caching, and serves duplicate calls from cache.
04
fluiq.eval()
LLM-as-judge scores every response. Warn or block based on your quality thresholds.

# 4. Score and gate every response (all tiers)

Framework-agnostic
Works with the stack you already use.
Fluiq patches at the function-call level, not the framework level. Any Python function that hits an LLM or vector database becomes a traced span with one decorator.
from fluiq import instrument, trace
instrument(api_key="fl_...")
@trace
def answer_question(question: str) -> str:
docs = vector_store.search(question, k=5)
return llm.invoke(prompt(question, docs))
# Every call is now:
# Traced with cost + latency
# Security-scanned
# Cached if repeated
