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 desktop app · separate cloud plans
Ask AI questions about your documents and files.
The local desktop app and self-hosted software have a free MIT-licensed option. Cloud hosting and selected external model APIs can charge separately. Local model use still requires your device resources; free software does not include every model provider.

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 1,000 credits/month · paid upgrades
Turn web pages into text and data for AI apps.
The hosted Free plan includes 1,000 credits each month. Hobby is USD 19/month billed monthly or USD 16/month billed annually for 5,000 monthly credits. Endpoint credit charges vary; optional paid-plan top-ups and extra usage can add charges.

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 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 Community self-host · paid cloud
Get a clear view of website traffic through a lightweight, privacy-conscious analytics dashboard.
The Community Edition can be self-hosted under AGPL without a software subscription; you fund its server and maintenance. Plausible Cloud is paid and offers a 30-day trial, not a permanent free hosted plan. Pricing depends on traffic and the selected tier.

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 self-hosted option · paid managed service
Build and run AI agents that handle recurring work for you.
Self-hosting has no license fee; you pay for infrastructure and model providers. The hosted Platform is paid with usage-based runs. Platform code uses Polyform Shield for personal/internal business use; classic components are MIT, so the whole platform should not be described as MIT open source.

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.
