Hexabot
HexastackChatbot and agent builder from Hexastack for multi-channel, multilingual conversational agents. It offers a visual flow editor, a plugin and extension system, and integrations with several model providers alongside channels such as WhatsApp, Telegram, Slack and Facebook. Agentic workflows are defined in YAML with typed runtime contracts, memory and MCP integration points.
The license changes after a delay, which GitHub cannot classify and the openness axis resolves. A self-hosted community edition runs without a license key. Verified 2026-08-11 via the Hexastack/Hexabot repository, its LICENSE.md and the vendor pricing page.
Openness
2 high confidence- license
- FCL-1.0-ALv2 (Fair Core License, NOT OSI
- source
- public(full TypeScript monorepo, packages/api + frontend + widget + agentic + graph + cli, docker/ compose)
The Fair Core License is a delayed-open, fair-code model, so the current core is source-available rather than open source: it converts to Apache-2.0 two years after each release, and competing or hosted commercial use is restricted until then. A direct read of the repo confirms the source is public - Hexastack/Hexabot publishes the whole runtime as a pnpm/turbo TypeScript monorepo (packages/api, frontend, widget, agentic, graph, cli) with Docker compose files, 55MB in all, and GitHub reports the language as TypeScript. Source that is published but restricted against competing use scores as source-available whatever the internal arrangement of the core. The pricing page does add a license-key mechanism worth recording: Community is free and self-hosted with no key, while the $19, $59 and $149 plans raise user, workflow and activation quotas through license-key activations, and LICENSE.md forbids circumventing that key. That is a capacity cap rather than a withheld feature.

Capability
4 high confidenceBroad conversational-AI platform spanning authoring, channels, LLM integration and agentic workflows: a visual chatbot flow editor, multilingual support, a plugin marketplace, multi-channel connectors for WhatsApp, Telegram, Slack and Facebook, and, in v3, agentic workflows with MCP support. The repo leads on agentic workflows across channels defined in YAML, with typed runtime contracts, action-based execution, explicit memory definitions, MCP integration points and multi-channel continuity - a wide enough agentic surface to hold the band level with Dify.
