Google Opal is a free no-code builder for chaining prompts, models and tools into shareable AI mini-apps.
Overview #
Google Opal #
Google Opal is a free no-code builder for AI mini-apps from Google Labs. In Opal you describe what you want in plain language, then refine it on a visual canvas where each step — a prompt, a model call, a tool — chains into the next, and the finished mini-app can be shared with a link. It sits below the app builders that generate real codebases: the output is a workflow other people can run, not a deployable application, which makes it the fastest way to turn a repeated prompt sequence into something a colleague can use.
Production credibility: Opal is a Google Labs experiment and is free, with no paid tier announced as of September 2026. It expanded to more than 160 countries in November 2025 and is reachable from the Gemini web app. The most significant addition since launch is the Agent step, released on 24 February 2026 and powered by Gemini 3 Flash, which plans an approach, picks tools and models itself, and executes rather than following a fixed chain. Because it is a Labs product, usage limits and capabilities move more often than in a commercial tool.
Key Features
- Natural-language description turned into a working mini-app
- Visual canvas for editing each step of the chain
- Agent step that plans, picks tools and executes on its own
- Shareable links so others can run what you built
- Available in more than 160 countries and inside the Gemini web app
- Free, with no paid tier announced
Ideal Use Case
Anyone who has the same multi-step prompt sequence saved in a document and keeps pasting it — research then summarise then format, or draft then critique then rewrite. Opal turns that into something shareable without code, which suits operations, marketing and teaching use far more than it suits engineering.
How Google Opal differentiates
Lovable, Bolt and GitHub Spark generate applications with real code you can deploy and own. Opal deliberately stops earlier: the unit is a chained workflow, hosted by Google, shared by link. That makes it far quicker for small internal tools and useless for anything you need to host yourself. The Agent step narrows the gap with agent builders, and the price — free — makes it the obvious first thing to try before paying for a builder.
FAQ
Q: What is Google Opal? A: Opal is a free no-code builder from Google Labs for creating AI mini-apps. You describe the app in natural language, edit the chain of steps visually, and share the result by link.
Q: Is Google Opal free? A: Yes. Opal is a free Google Labs experiment with no paid tier announced as of September 2026, though usage limits may apply.
Q: Where is Opal available? A: In more than 160 countries since November 2025, and reachable from the Gemini web app.
Q: What is the Agent step in Opal? A: Released in February 2026 and powered by Gemini 3 Flash, the Agent step plans its own approach, selects tools and models, and executes, instead of running a fixed sequence you defined.
Q: How is Opal different from Lovable or GitHub Spark? A: Those tools generate real applications with code you can deploy. Opal builds hosted, shareable workflows without code, which is quicker for small internal tools and not suitable when you need to own the codebase.
tl;dr
Google Opal is a free Google Labs no-code builder for AI mini-apps: describe it in words, refine the chain on a visual canvas, share by link. Available in 160-plus countries, with an Agent step powered by Gemini 3 Flash.
