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

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 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 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 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 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.

Pricing not verified

Free development app · agent costs
Run coding agents side by side in a development environment organized around parallel work.
The provider describes Orca for macOS, Windows and Linux as free and open source. Connected coding agents, API providers, subscriptions and remote machines have their own costs. No included paid-agent allowance is assumed.
