What it is¶

Google Opal is a no-code alternative to small custom web apps, built for people who want shareable AI workflows without running a server.

• Workflow editor: builds and edits node-based pipelines from natural language.
• Visual canvas: chains inputs, prompts, model calls, tools, and outputs.
• Agent Mode: selects tools, uses memory, routes execution, and conducts follow-up chat.

Development line¶

• 2025-07-25 — Google introduced Opal. On 2025-07-25, Google published an introduction to Opal and shared its web entry point. The launch confirmed the project, but did not establish its full feature set, regional availability, or account limits.

What changed¶

• 2025-07-25 (original announcement dated 2025-07-24) — Opal launched in U.S.-only public beta as a visual and natural-language builder for multi-step apps chaining prompts, model calls, and tools.
• 2026-02-25 (official announcement dated 2026-02-24) — The Generate step gained Agent Mode to pick tools and models against a goal, retain memory, route dynamically, and ask follow-up questions.
• 2026-03-24 — First-party documentation shows Agent Mode enabled by default, exposing Search/Maps, Code Exec, Memory, and media generation. Fixed workflows remain available for rigid or high-precision logic.

How to use this¶

We evaluate Google Opal through its official introduction and web entry point from 2025-07-25. Official documentation shows no later workflow or capability changes.

1. Sign in to Opal, open a Gallery demo, and select Remix to create an editable copy. Select Create New to build an app from scratch. — https://developers.google.com/opal/quickstart
2. For open-ended workflows, add a Generate step, turn on Agent if needed, and define the target outcome. — https://developers.google.com/opal/Agent_Mode
3. Reference needed capabilities with the @ menu, such as @Search or @Memory, then link inputs, generation steps, and outputs in the visual editor. — https://developers.google.com/opal/Agent_Mode
4. Preview the app with representative inputs, inspect the resulting graph, and refine prompts or nodes before sharing. — https://developers.google.com/opal/quickstart
5. Keep an Opal private by default. When sharing, restrict users to the app view or grant full editor and remix access. — https://developers.google.com/opal/faq

Best practices¶

• Remix an existing Gallery app rather than designing the first workflow on an empty canvas. — https://developers.google.com/opal/quickstart
• For Agent Mode, specify the goal and required output rather than prescribing every intermediate step. — https://developers.google.com/opal/Agent_Mode
• Call tools explicitly with @ when you need a particular capability, which official documentation describes as more precise. — https://developers.google.com/opal/Agent_Mode
• Test prompts and the full workflow before relying on it, because Opal can make mistakes. — https://developers.google.com/opal/faq
• Treat remix and editor sharing as prompt disclosure: sharing exposes prompts, the workflow graph, and the underlying Drive file. — https://developers.google.com/opal/faq

Superseded by this¶

• 2025-07-25 — The original U.S.-only public beta access rule is obsolete: the current FAQ lists supported countries instead of restricting access to the U.S.
• Before 2026-02-25 — Treating every Opal purely as a static prompt chain is obsolete for open-ended tasks; Agent Mode adds tool selection, memory, routing, and interactive chat. Fixed workflows remain appropriate for rigid or high-precision logic.

Still unknown¶

• We ran no signed-in tests, leaving quotas, billing, publication caps, and account-specific feature availability unverified.
• Chinese-language searches found no first-party Simplified-Chinese Opal documentation, so guidance relies entirely on official English sources.
• Availability remains country-specific; check the current official FAQ before committing a workflow to Opal.

Agent brief¶

• Subject: project:google-opal, thread google-opal, 1 dated events 2025-07-25 → 2025-07-25.
• Practical note: From 2025-07-25, practitioners could evaluate Google Opal through Google's official project introduction and linked web entry point; the supplied evidence does not establish a later workflow or capability change.
• Confidence: medium. Dated supersedes above are the authority for what is obsolete.
