Tally has the most generous free tier of any tool in this market: unlimited forms, unlimited submissions, conditional logic, file uploads, payments, and webhooks with no time limit and no credit card. Used as a waitlist via an email-capture form. The gap: no queue mechanic, no position tracking, and no referral system.
Key differences
Tally collects email addresses — it has no concept of a queue. There is no position, no ordering guarantee, no idempotency on re-submission, and no API that returns where someone stands. Enlist is the layer that turns email collection into a position-assigned, transactionally-safe queue.
With Tally you find out how many people signed up after the fact, in a dashboard. With Enlist, the signup response includes position and total immediately — your form can render "you're #47 of 1,203" without a second request.
Tally sends a notification to the form owner, not a confirmation to the respondent (without Pro). Enlist sends a confirmation through your email provider and writes delivery, open, and click events back onto the signup row.
Tally has no developer API beyond webhooks. Enlist exposes every operation over a hosted MCP endpoint — a coding agent can create the waitlist and wire the signup handler in one prompt.
Up to 500 signups on the free tier. Add the MCP server and your agent wires the whole integration in one prompt.
