GHOST PREVIEW

Zero-Token Dry Run

Run the interpreter in fast-forward against live state — nodes light up showing exactly what path a run would take without writing anything or spending tokens.

LATENCY HEATMAP

Per-Node Cost Metrics

Per-node latency, token, and dollar costs rendered straight onto the canvas. Toggle heatmap mode to spot slow or expensive branches at a glance.

TIME SCRUBBER

1×–8× Speed Playback

A timeline scrubber replays any past execution — nodes glow and dim in sync with adjustable playback speed so you can debug divergent paths.

BUDGET CAPS

Hard Cost Limits

Set max cost, token, and step caps per node. The interpreter stops runaway agents before unexpected bills occur.

08. ENTERPRISE SECURITY & GOVERNANCE

[ ZERO TRUST RUNTIME ]

Single-Use Idempotency Tokens

Every approved write action generates a single-use token, enforced atomically in the database — replays and concurrent duplicates are blocked.

Multi-Tenant Isolation

Strict PostgreSQL tenant boundaries isolate skills, versions, graph executions, and approval records per user account.

Hard Execution Limits

Enforces maximum step boundaries and loop cycles to prevent infinite loops, runaway costs, and resource exhaustion.

Circuit-Breaker Failover

A single model failure never stops a run — the router parks the failing provider in adaptive cooldown and transparently moves to the next healthy model.

Atomic Commit Transactions

Skill creation, draft rotation, publish, and execution traces commit in atomic transactions — a crash can never orphan data.

Full Audit Trails

Every mutation writes a structured log and audit row (SKILL_PUBLISHED, APPROVAL_GRANTED, RECOVERY_STARTED) traced back to the acting user.

// 09. FREQUENTLY ASKED QUESTIONSARCHITECTURE & FAQ

How does the Open-Source & Zero-Key Stack work?

Agent Studio embeds native connectors for SearXNG (privacy metasearch), Crawl4AI (LLM-friendly scraper), IBM Docling (PDF/table parser), Gotenberg (PDF exporter), Qdrant (vector database), and PocketBase/NocoDB (SQLite & Airtable). These tools can run against public instances with zero API keys or against your self-hosted Docker containers with zero subscription costs.

How do n8n and Dify.ai workflow imports work?

Agent Studio includes universal converters in /lib/converters that translate n8n JSON nodes and Dify DSL YAML workflows into native Agent Studio visual graph nodes. You can browse over 11,600 n8n workflows and 290 Dify blueprints in our Unified Marketplace and launch them with 1 click.

How does Model Context Protocol (MCP) integration work?

Agent Studio is a full dual-mode MCP Client and MCP Server. As a client, it searches 136,500+ MCP servers across Smithery, Glama, Composio, Arcade, and mcp.so and mounts them into agent graphs. As a server, external IDEs like Cursor and Claude Desktop can call your published workflows via /api/mcp/sse.

What makes Agent Studio different from Langflow, Flowise, or n8n?

Unlike traditional ETL tools that only execute linear DAGs, Agent Studio is designed specifically for autonomous Multi-Agent orchestration — supporting supervisor loops, critic reflection, map-reduce fan-out, human-in-the-loop idempotency tokens, and real-time SSE execution telemetry.

How does the 28+ Free Model Failover Router protect my runs?

Every LLM step routes through a resilient circuit-breaker router supporting 28+ free models across OpenRouter and Groq spanning 8 specialization domains. With context windows up to 512k tokens and speeds up to 750 t/s, if any model hits a rate limit (429) or outage (5xx), the router seamlessly quarantines it and falls over to the next healthy model with $0 token expense.

How do Human-in-the-Loop (HITL) write locks guarantee safety?

Whenever an agent reaches an approval node (e.g. before spending money, modifying a database, or sending emails), the execution is paused in PAUSED_FOR_APPROVAL. An atomic single-use cryptographic token is generated in PostgreSQL — guaranteeing the action cannot be dispatched twice.
