Kavela vs LangChain
LangChain is a code library: you write the agent, wire its tools, and host and operate it yourself. Kavela builds the agent from a plain-English description and runs it, including tool wiring, credentials, memory and the runtime. A library gives you maximum control; a platform gives you a working agent sooner.
What LangChain is good at
- Total control. Anything you can express in code, you can build.
- A very large ecosystem of integrations and community patterns.
- No platform lock-in, since you own and host the code.
Where Kavela works differently
- You do not write or host the harness. Tools, memory, credential handling and the run loop are provided.
- Credentials are handled at two mutually exclusive layers, so each user of your agent can connect their own accounts without you building that.
- Runs execute in a durable server-side object, so a run survives disconnection without you building that infrastructure.
- A published agent gets a shareable page and a marketplace listing.
Which one should you pick?
Pick LangChain if
You want to own the harness, you have unusual requirements, or hosting it yourself is a requirement rather than a cost.
Pick Kavela if
You want the agent running rather than the harness built. Our bar is that two hours on Kavela beats two hours of wiring your own.
Build an agentThe honest version
Kavela is early. It is bootstrapped and small, and not everything is built. If the comparison above made LangChain sound like the better fit for your case, it probably is. The fastest way to settle it is to describe an agent and see what gets built in a few minutes.
