BotFramework-WebChat

Why we included this project

Web Chat is Microsoft's React-based chat widget for the Bot Framework, and it fills a real gap: teams that build a conversational bot still need something decent to put on the page, and this gives them a front end they can drop in and then reshape. It is built for Bot Framework v4 and Azure Bot Services, so the initial wiring is minimal, yet it stays useful after setup because nearly every part of the transcript can be restyled, Adaptive Cards render inline, and responses can stream in live as the bot produces them. Accessibility and content-security support come bundled, which makes it a sensible default for customer-facing interfaces where you would rather not build message rendering and input handling from scratch. One thing worth knowing: the Bot Framework SDK was archived at the end of 2025, but this Web Chat component is still maintained on its own.
