OpenAI Agent Builder is shutting down. Your agents don't have to.
OpenAI deprecated its visual Agent Builder after eight months — shutdown lands November 30, 2026. If you build visually, Falcon Builder is where those agents live next: the same canvas workflow, minus the single-vendor lock-in, plus deployment surfaces ChatGPT will never give you.
What you gain in the move
Any model, your keys
Keep GPT where it's best, use Claude or Gemini where they're better — per-node. BYO API keys with zero token markup, so a model vendor can never squeeze your margins or sunset your platform again.
Deploy outside the chat app
Publish agents as branded chat pages, website widgets, forms, and WhatsApp & SMS lines — white-label, on your domain, gated by password, email, or SSO. Your agent becomes your product, not a tab inside ChatGPT.
Production controls built in
Draft/publish versioning with rollback, a node-by-node live-run debugger, human-approval steps in Slack, execution logs, and HIPAA-grade PII redaction on Enterprise. The unglamorous parts that keep agents in production.
How migration works
Map your graph
Agent Builder nodes map one-to-one: triggers, LLM steps, conditions, tool calls, outputs.
Rebuild or generate
Rebuild on the canvas, or describe the agent and the AI Generator scaffolds it in minutes.
Test node-by-node
Run each node inline with real data before anything touches production.
Publish anywhere
Hosted chat, embed script, forms, WhatsApp, SMS — with version history and rollback.

Frequently asked questions
When does OpenAI Agent Builder shut down?
OpenAI announced the deprecation of Agent Builder on June 3, 2026, with shutdown on November 30, 2026. OpenAI points users to the code-first Agents SDK or Workspace Agents inside ChatGPT.
Can I keep using GPT models after migrating?
Yes. Falcon Builder supports OpenAI, Anthropic, Google, Mistral, Ollama, and OpenRouter — bring your own API keys with zero token markup, and swap models per-node. Your prompts and logic carry over; only the canvas changes.
How is Falcon Builder different from Workspace Agents?
Workspace Agents live inside ChatGPT: they can’t be white-labeled, embedded on your own domain, or shipped to your customers as your product. Falcon Builder publishes agents as hosted chat pages, website widgets, forms, and WhatsApp/SMS lines — on your brand, with password, email, or SSO access control.
What does migration actually involve?
Agent Builder workflows are node graphs, and so are Falcon Builder workflows: triggers, LLM steps, conditions, tool calls, and outputs map one-to-one. Most agents rebuild in under an hour — or describe the agent to our AI Generator and it scaffolds the workflow for you. Guardrails map to condition nodes and human-approval steps; ChatKit embeds map to our interface embed script.
What happens to my evals and versioning?
Falcon Builder has draft/publish deploys with full version history, rollback, and a node-by-node live-run debugger — you can watch every execution step and replay failures, which is where most agent debugging time actually goes.
