What our research says

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

Epsilla

Epsilla fits organisations that want a hosted place to assemble document-grounded agents and that value having on-premise or private-cloud options. The self-serve tiers are tight on message volume, so real use quickly moves into the higher plans or the add-on meters.

Pros

  • Agent builder, RAG hosting and monitoring in a single product
  • Managed SaaS, private cloud and on-premise deployment options
  • Clear self-serve pricing with per-seat and per-message add-ons
  • Trust centre and SLA are published

Cons

  • Free tier allows only 50 messages a month and wipes data after 30 days of inactivity
  • Starter and Professional message allowances are listed against a specific OpenAI model, which may constrain model choice
  • Positioning has shifted from vector database to agent platform to harness routing, so documentation can be uneven

Which one fits

Choose Dify if you need

  • Teams that want to self-host an agent and RAG builder without writing the orchestration layer
  • Product groups where non-engineers configure prompts and knowledge while engineers wire tools and APIs
  • Enterprises that need private deployment with SSO and audit logs for internal LLM apps

Choose Epsilla if you need

  • Teams building internal or customer-facing agents on private documents without an ML team
  • Regulated companies that need private-cloud or on-premise deployment
  • Agencies prototyping vertical agent solutions for clients
