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

Free self-hosted UI · model costs
Chat with AI models in your own browser-based workspace.
Use the self-hosted UI with its required branding under the current license. There is no included paid-model allowance: cloud APIs, servers and storage can cost extra. Removing branding or qualifying enterprise uses may require a separate license; do not assume the current release is unrestricted BSD.

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 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 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 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 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 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 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.
