sipi.bot vs Cursor
Cursor is a coding IDE with built-in usage controls; sipi.bot is a pre-spend firewall for autonomous agents. They answer different questions: Cursor tells you how much you've used, sipi.bot decides whether a purchase may happen.
What Cursor does well
Deep IDE integration with AI features that teams genuinely love.
Usage-based pricing with included usage on plans — predictable for solo devs.
Built-in limits and notifications that surface spend after the fact.
Excellent for controlling one vendor: Cursor.
Where Cursor falls short
Limits are per-provider and post-hoc — they tell you when you've crossed a line, not before.
They only govern Cursor itself. Agentic tool calls, compute purchases, and third-party APIs in your workflow are out of scope.
No merchant allowlist, category rules, or per-agent approval queue for agent spend.
Where sipi.bot wins
Pre-spend decisions: APPROVED, BLOCKED, or FLAGGED before money moves.
Covers every merchant and every provider, not just one IDE.
Deterministic rules engine — no model call in the decision path.
Queryable audit log with the rule that fired and why.
When to use which
Use Cursor's limits for Cursor. Add sipi.bot when your agents spend beyond the IDE — compute, APIs, payments. They compose: sipi.bot decides, Cursor executes.

FAQ
Are Cursor and sipi.bot competitors?
Not really. Cursor controls its own usage; sipi.bot governs agent spend across all merchants. Most teams that run Cursor-based agents use both.
Does sipi.bot work inside Cursor?
Yes — sipi.bot is an MCP tool, and Cursor supports MCP, so agents in Cursor can call the guard before spending.
Which is cheaper?
Cursor charges per seat with included usage. sipi.bot is a flat $99/mo (Team) or $499/mo (Business) with unlimited evaluations, plus a free MIT self-host core.
