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

Free local · paid cloud
Download and run AI models on your own computer.
Local models are free to run on your own hardware. Cloud Free includes limited starter usage; Pro is USD 20/month and Max USD 100/month. Usage credits and model token rates apply, and paid allowances do not roll over.

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 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 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 assistant software · provider costs
Connect an AI assistant to the tools and conversations where you already work.
The MIT-licensed assistant software is free to run on your own machine. Cloud models, connected services and hosted machines can require payment; subscriptions or API keys are supplied separately.

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.

Free local runtime
Run language model inference across different hardware with a portable C and C++ engine.
The MIT-licensed inference runtime has no software license fee. Supply suitable hardware and check each model license. Rented GPU or server resources and unrelated hosted services can cost extra.

Free self-hosted app · agent costs
Coordinate AI agent teams through shared goals, task ownership, and cost visibility.
The MIT-licensed local/self-hosted app has no Paperclip account requirement or software license fee. You supply model/provider access and any server or database resources, which can cost extra. Hosted offerings are separate from this local edition.
