Pricing questions

Why per instance instead of per message?

Messages are unmetered. WhatsApp infrastructure cost scales with stateful connections — one Baileys socket per instance — not with throughput. Pricing should match the cost shape.

What are the rate limits?

Starter is capped at 60 req/min, Pro at 300, Max at 1500. Webhook delivery is unlimited and queued; the cap is on inbound REST calls.

Can I downgrade?

Yes. If you exceed your new plan's instance count, the oldest instances move to read-only until you bring the total back under cap.

Can I self-host?

Yes. The gateway is a single Node process you can run on Railway, Fly, Hetzner, or your laptop. Self-hosted users get the same contracts package and a community-supported deployment guide.
