Google's asynchronous coding agent works on repository tasks in a cloud environment and proposes changes for review.
Free plan
The base Jules tier lists daily and concurrent task limits. Paid Google AI plans raise those allowances; repository access and a supported account are required.
Free tiers can restrict usage or features. Paid upgrades are separate.
The official pages used to check this listing.
Google AI Studio
Coding
Google AI Studio is a browser workspace for experimenting with Gemini prompts and building AI prototypes. It exposes model controls and multimodal inputs that are useful when comparing responses or planning an API integration. Free access is rate limited and does not cover every model or capability.
Bolt
Coding
Bolt builds websites and web apps from natural-language instructions in a browser workspace. You can preview the result, revise the interface and work with project files. Its token allowance makes the free plan useful for testing an idea or making a modest prototype before investing in a larger build.
Cursor
Coding
Cursor is an AI code editor for working directly with project files, asking questions about a codebase and requesting changes through an agent. Its free Hobby plan suits occasional coding assistance and trying its Composer workflow. This entry requires downloading a desktop editor rather than using a standalone browser chatbot.
GitHub Copilot
Coding
GitHub's coding assistant explains code, proposes changes and supplies inline suggestions across supported editors and GitHub surfaces. The Free plan is useful for occasional debugging, learning a language or trying AI assistance on an existing repository. Editor integration requires installing a supported extension.
