01
Open-source platform for building production-ready LLM apps and agents.
Dify is a strong pick if you want an all-in-one, self-hostable platform to build LLM apps quickly, and its open-source community is genuinely large and active. Be aware of two things: the license is not fully permissive (no multi-tenant resale, no branding removal), and the real bill at production scale is dominated by separate LLM token spend rather than Dify's platform fee. Self-hosting is free but adds operational overhead.

02
Build AI support agents trained on your own data, no code required.
Chatbase is a mature, widely adopted no-code AI chatbot builder that is unusually capital-efficient, having reportedly reached roughly $10M ARR bootstrapped with a small team. The credit-based pricing is its main gotcha: every response consumes credits, premium models cost more, and add-ons for extra agents and branding removal can raise the real bill well above headline prices. Model your expected message volume before committing.

03
A collaborative platform to design, build and ship AI agents.
Voiceflow stands out for collaboration and design: teams can map, prototype and ship chat and voice agents on a shared visual canvas with support for multiple LLMs. That polish comes at a price, with editor seats starting around $60 per month plus a usage-based credit layer, so both seats and interaction volume drive cost. It is a strong choice for teams that value cross-functional collaboration, less so for a single builder on a tight budget.
