The honest brief
Opal
Turn a plain-language description into a shareable, visual mini-app that chains prompts, models, and tools — no code, hosted by Google.
- Natural-language app building
- Visual node editor to refine logic
- Share finished apps via a link
- Free Google Labs experiment
- Starter templates and demo gallery
- Experimental Labs beta, may change
- Tied to Google's model ecosystem
- Availability still limited by country
- Not aimed at complex production apps
Relay.app
Bakes human steps — approvals, input forms, AI-output review — natively into flows, not bolted on like rival tools.
- Native human-in-the-loop steps
- Per-step choice of AI provider
- Collaborative team workflows
- Built-in AI extract/classify steps
- ~200 integrations, fewer than Zapier
- Newer/smaller ecosystem
- Web-only, no self-host
