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

Free local app
Chat with AI on your computer, including offline models.
Jan Desktop is free under Apache-2.0. Local inference has no per-message software fee; hardware, electricity and model licenses still apply. Connected cloud providers have their own API prices.

Free Sandbox · paid cloud plans
Build AI chatbots and automated workflows.
Cloud Sandbox is free with limited credits and storage. The provider lists Professional at USD 590/workspace/year and Team at USD 1,590/workspace/year on annual billing, before applicable taxes. Community self-hosting uses your infrastructure; model API keys and paid features can add costs.

Free self-hosted · paid managed plans
Plan your social calendar, coordinate publishing, and manage multiple channels from one workspace.
The self-hosted open-source application has no software subscription, but infrastructure and optional AI/provider APIs may cost extra. Managed Postiz starts at USD 29/month and has a seven-day trial; it does not have a permanent free hosted plan.

Free project tier · Pro from USD 25/month
Add a database, user accounts, and file storage to your app.
The hosted Free plan has limited database, bandwidth and storage allowances. Pro starts at USD 25/month; extra projects, compute, storage and add-ons can add charges. Self-hosting uses your own infrastructure rather than including managed cloud resources.

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 database tier · paid upgrades
Create structured databases and internal applications through a visual, no-code interface.
A USD 0 plan is available with edition-specific limits. Premium is USD 12/user/month billed monthly or USD 10/user/month on annual billing; Advanced is USD 22 monthly or USD 18 on annual billing. Self-hosted paid features and your own infrastructure have separate costs.

Free whiteboard · paid Plus workspace
Draw diagrams and whiteboards in your browser.

Free Community · paid hosting/features
Connect apps and automate repeated tasks.
Self-hosted Community runs indefinitely without a paid license key. Registered Community also remains free. Business/Enterprise features and n8n Cloud are paid; your server, third-party services and model APIs can add costs. Its source-available license is not a general permission to sell a competing service.

Free local runtime
