Why developers choose Widgent
Actions, not just answers
Chatbase answers questions from your documents. That's it. Widgent agents can answer questions AND take actions — fetch live data from your APIs, update records, trigger workflows, navigate your UI. A fundamentally different capability.
No per-message tax
Chatbase charges message credits on top of its monthly fee. At scale, you're paying Chatbase a markup on every LLM call. With Widgent you supply your own API key — you see exactly what you're spending on your OpenAI or Anthropic invoice.
User identity built in
Widgent supports signed JWTs so the agent knows exactly which user it's talking to and can be given context about them (plan, permissions, account data). Chatbase has no concept of user identity — every chat is anonymous.
Headless and fully programmable
Widgent's headless embed lets you build any UI you want while Widgent handles streaming, tool execution, history, and LLM routing. Chatbase gives you an iframe — take it or leave it.
