Anonymous posting in Slack. Without the per-user bill.
If you're evaluating OpenSay, here's what we'd want to know in your shoes: Anony Botter covers the same 80% use case — anonymous messages, polls, pseudonymous replies — at roughly 1/11 the entry price, with a free tier that doesn't cap at 10 posts a month.
The headline numbers, verified April 2026.

- Enterprise

Six reasons teams move to Anony Botter.
Pay 1/11 the entry price
OpenSay's Business tier is $79/month. Anony Botter Plus is $7/month billed annually ($8 monthly). You keep anonymous messaging, polls, and pseudonyms — at a tenth of the cost.
Escape per-user pricing at scale
OpenSay Enterprise is $0.60/user/month with a 1,000-user floor — a 2,000-person team pays $1,200/month. Anony Botter Enterprise is $29.99/month flat, no matter the team size.
Free tier that survives past trial week
OpenSay Hobby caps at 10 posts and 10 replies per month. Anony Botter's free tier gives you 20 messages + 3/day, unlimited polls, and unlimited thread replies — indefinitely.
Reply-notification DMs OpenSay doesn't ship
We DM the original poster and every prior replier when a new reply lands — with zero identity exposure. It's the feature that keeps anonymous threads from dying after the first reply.
OP badge on top of pseudonyms
Both bots ship pseudonyms. Only Anony Botter adds an Original Poster badge so you can tell when the thread's author is responding versus a third anonymous voice joining in.
Real admin guardrails, every tier
Block @here/@channel, disable broadcast-to-channel, toggle thread replies — all included on every tier. OpenSay's moderation leans AI; ours leans explicit admin controls.
What you keep. What you give up.
We'd rather tell you upfront than surprise you on day three. If any of the “give up” column is load-bearing for your team, stay on OpenSay.

Four steps. Under a minute.
There's no data migration because there's no user-linked data on either side — by design.
Uninstall OpenSay
Slack → App Directory → OpenSay → Uninstall. Your historical posts stay in the channel as static content. Nothing identifying is lost because nothing identifying was ever stored.
