The Composio alternative
serious builders trust.
Secure token vault, enterprise auth patterns, and authorization controls — built for the questions your customers will actually ask.
Every credential lives in an isolated vault — encrypted with its own unique key, with the key layer stored entirely outside the data plane. Compromising the database alone is not enough to read a token.
You register your own OAuth app and hold your own API keys. They're yours — if something goes wrong, you act directly, without going through Scalekit.
"Our agents act across Salesforce, Gong, Google Drive, and more, on behalf of every customer. Scalekit behind the scenes meant we can keep adding tools without ever rebuilding how credentials or tool calling work."
Define what each tool is allowed to do — not just which OAuth scopes the user granted. An agent with Salesforce access can be scoped to read-only on opportunities, write-only on notes. Enforced at the proxy on every call.
The user's actual role in the connected system sets a hard ceiling on the agent. An agent acting for a sales rep cannot reach records or take actions that rep couldn't take themselves.
Scalekit can verify who the human is before the agent acts — not just "were credentials granted at some point," but "is this the right person authorizing this action right now.
