Head to head

OpenTag vs Zapier

Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

OpenTag

AI coworker that lives in Slack, takes tagged tasks, routes each one to one of 80+ models and offers to run repeated requests on a schedule. $200 free trial; Team is $50/mo for 5,000 shared credits.

Where OpenTag fits

Zapier

Where they pull apart

OpenTag

Stands out: OpenTag is priced per job, not per seat, so everyone in an invited channel shares one coworker. It notices repeated asks and offers to automate them, instead of waiting for someone to build a workflow.

Watch out: Slack is the only generally available platform; Microsoft Teams is invite-only. SOC 2 Type II is in progress, not complete, and the vendor lists job costs as ranges from 25 to 1,250 credits.

Not the right fit for

Teams on Microsoft Teams that need general availability now
Buyers who need a completed SOC 2 report today

Zapier

Stands out: Zapier MCP is on every plan, including Free, and connects AI assistants to the same 9,000-app catalog.

Watch out: Each MCP tool call uses two tasks. Free Zaps are limited to two steps, and Professional is a single-user plan.

Not the right fit for

Builders who need self-hosting and per-execution billing
Heavy AI use where every MCP call costs two tasks
