We looked for open-source platforms to build AI support agents like Decagon. We verified each project's license, recent activity, stars, and self-hosting in its repository. See our methodology for the full criteria.
Parlant is an Apache-2.0 conversational AI server that uses context-aware guidelines to keep agent behavior consistent, with full traceability. Botpress is a visual agent builder with many integrations, but its hosted platform is proprietary.
Typebot is a visual editor for chatbots, Hexabot is a self-hosted agent platform with workflows, memory, and MCP, and Tiledesk is a no-code agent platform across web, WhatsApp, SMS, voice, and email.
Typebot uses the Functional Source License and Hexabot uses the Fair Core License, so both are source available. Botpress components are MIT, and Tiledesk is MIT with enterprise images.
Parlant is Apache-2.0. Botpress public components and Tiledesk are MIT. Typebot is FSL. Hexabot is FCL-1.0-ALv2.

Decagon is a proprietary enterprise support-agent product. Open-source platforms let you control models, data, and behavior, but you build the evaluation, integrations, and guardrails yourself.
Parlant is an Apache-2.0, self-hostable conversational AI server that manages agent behavior through context-aware guidelines and journeys, so agents follow your rules more predictably. It is built around guidelines rather than a visual flow builder, and is aimed at developers building customer-facing agents.
Pricing: Free and open source; model costs apply.
Botpress provides visual agent development, integrations, SDKs, plugins, tools, actions, and multi-channel conversational workflows. The current MIT public repository primarily contains SDK and integration tooling rather than the complete hosted platform.
Pricing: Hosted platform and services may be paid; complete current platform is not fully self-hostable.
Typebot is a visual chatbot builder for questions, conditions, variables, forms, webhooks, API integrations, embeds, payments, and custom logic. Current versions use a Functional Source License and are described as Fair Source.
Pricing: Self-hostable source available software; current license is not OSI-approved.
Hexabot combines visual workflows, actions, AI agents, persistent memory, RAG, MCP tools, custom tools, channels, PostgreSQL, and extensibility. Current v3 releases use the Fair Core License with Apache-2.0 as a future license.
Pricing: Source available under FCL; verify current commercial and future Apache-2.0 terms.
Tiledesk is an MIT-licensed platform for building LLM-enabled support chatbots that hand off to human agents, across web, messaging, email, and voice channels, with Docker Compose and Helm deployment. Tiledesk Enterprise customers can request credentials to pull private enterprise-only images.
Pricing: Free to self-host the open-source edition; enterprise features and cloud plans are paid.
