Pricing
Pricing that scales with your agents.
Start in a sandbox your agent can't hurt anyone from, extend with pay-as-you-go credits, and move to a plan when you go to production. The full security pipeline runs on every tier — scanning is never the upsell.
Private beta · invite-only. Beta members lock in a 30% discount for the life of their plan.

Prices in USD; applicable tax is calculated at checkout. Annual billing is two months free. The daily send limit is the packaging unit on every tier — it is the number the send gate enforces, and it doubles as a deliverability and abuse control; monthly figures are approximate. A new Pro account reaches its full 1,000/day over its first 72 hours on the shared sending pool; verifying your own domain lifts that immediately. ReplyLayer handles transactional, operational, and reply-driven email only — it is not a bulk or marketing email tool.
