Dify
Dify is the pragmatic choice when a team wants a visual builder for agents and retrieval that it can self-host today and hand to non-engineers tomorrow; the Community Edition is real software, not a demo, and the 158K GitHub stars reflect that. Pay for Cloud only if you do not want to run Docker — the $59 Professional tier is one workspace with three seats and metered message credits, so a developer team will outgrow it or self-host. It is less suited to teams that want code-first pipelines or a single-vendor model stack.
Pros
- Open-source Community Edition with single-command Docker deployment and an active repository
- One canvas covers workflows, agents and a knowledge pipeline with retrieval testing
- Apps publish as API endpoints, embeds or MCP tools with logs and feedback built in
- Plugin marketplace for model providers, tools, data sources and MCP integrations
- Self-hosted and cloud editions share the same product, so you can move between them
Cons
- Cloud tiers meter message credits, members and storage per workspace, and annual billing is the headline
- The open-source licence carries commercial conditions (multi-tenant and logo clauses) rather than plain Apache
- Visual workflows get hard to review and version once they grow past a few dozen nodes
- Enterprise features such as SSO, RBAC and audit logs are reserved for the paid Enterprise edition
