Search for a tool or task, check its pricing, and open its official website. Freemium means a free plan with paid upgrades.

Free coding app · model costs
Use an AI assistant to write and edit code.
OpenCode software is MIT-licensed and free. A local model uses your own hardware; paid provider APIs or subscriptions bill separately. Optional OpenCode Go is USD 10/month and Go Plus USD 40/month, with model-specific usage limits.

Free Professional · paid organization plans
Design app screens and clickable prototypes with your team.
Hosted Professional is USD 0/user/month and includes the core design tools. Paid organization plans are separately offered, including USD 7/editor/month for the observed next tier. Self-hosting uses your own server and operational resources.

Free whiteboard · paid Plus workspace
Draw diagrams and whiteboards in your browser.
The basic Excalidraw browser whiteboard is free. Excalidraw Plus is a separate paid workspace with additional organization and collaboration features. Check its current billing selection and trial conditions before upgrading.

Free agent software · provider costs
Use a desktop AI agent with persistent context and integrations across communication platforms.
The MIT-licensed agent can run locally without a software license fee. Model APIs, optional Nous Portal subscriptions, search or other services, and cloud machines may charge separately. A free agent is not free access to every model.

Free self-hosted builder
Prototype AI workflows visually and connect components into runnable applications.
The published Langflow builder has a free self-hosted option. Your server, database, external model APIs and integrations may cost money. Any managed cloud allowance is a separate provider plan, not unlimited free model usage.
