Free during its Google Labs beta, Opal converts a plain-language app idea into an editable workflow on Gemini models, with an Agentic Mode for multi-step tasks.
Google Opal is a free no-code AI app builder from Google Labs, now available in more than 160 countries after launching as a US-only beta in 2025. It turns natural-language descriptions into visual, multi-step workflows built on Gemini models, connecting Google Docs, Sheets, Gmail, and Drive without writing code.
Opal is an experimental no-code app builder from Google Labs that launched as a US-only public beta on July 24, 2025. It lets anyone describe a workflow in plain English and turns that description into a visual chain of AI steps, connecting Gemini prompts, image and video generation, and Google's own apps into a single shareable mini-app. Google expanded access from the US to more than 160 countries by November 2025, one of the fastest global rollouts among its Labs experiments. The core interface is a visual canvas: each step in a workflow appears as an editable block, so a non-programmer can see exactly how a prompt flows into a search, an image generation call, or a spreadsheet update. In February 2026 Google added an Agentic Mode that uses Gemini 3 Flash to plan and execute multi-step tasks on its own, moving Opal from a fixed-flow builder toward an autonomous agent step. Live debugging lets a builder run a workflow one step at a time and see exactly where an error appears. Opal connects natively to Google Docs, Sheets, Gmail, and Drive, which makes it best suited to people already living inside Google Workspace: teachers building an interactive quiz generator from a YouTube video, product managers mocking up an internal tool, or hobbyists automating a personal research routine. It is not built for production software: there is no database layer, no code export, and every app stays hosted on a Google-issued link with no self-hosting option. Opal remains completely free during its beta, with no paid tier announced as of 2026, and Google has not said whether pricing will arrive once the product graduates from Labs. Google is also testing Model Context Protocol support, which would let Opal workflows call outside APIs and tools instead of staying limited to its own services. On December 17, 2025, Opal reached inside the Gemini app itself, appearing in the Gems manager so a user can build and reuse a mini-app without leaving their regular Gemini chat.
No cost while the product sits in Google Labs beta status, and Google has not announced a paid plan for 2026. Standalone Gemini API usage triggered by a workflow step is billed separately under Google's normal API pricing.
Google Opal is completely free during its Google Labs beta, with no paid subscription tier announced as of 2026. Every workflow runs on your existing Google account at no extra charge beyond any separate Gemini API usage a workflow step might trigger.
Yes, the entire product is free while it stays in beta status, with no premium plan, seat fee, or usage cap tied to a subscription. The tradeoff is experimental status, meaning features or availability can change without notice.
Lovable and v0 are stronger picks if you need to ship a production web app with a real database and exportable code, since Opal has neither. Replit suits developers who want full-stack hosting and version control rather than a Google-only mini-app link.
AI Studio is a developer IDE for testing Gemini prompts and API keys before writing production code, while Opal is a no-code canvas aimed at non-programmers building disposable mini-apps. Choose AI Studio to ship a real app on the Gemini API, and Opal for a quick internal tool.
Sign in with any Google account at opal.google.com, or open the Gems manager inside the Gemini app, and describe the mini-app you want in a sentence or two. Opal generates an editable step-by-step flow you can test live, tweak block by block, and share as a Google-hosted link.
