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. Daily send pacing applies on every tier as a deliverability and abuse control, not as packaging. ReplyLayer handles transactional, operational, and reply-driven email only — it is not a bulk or marketing email tool.
