Ando is team messaging where AI agents are members, not apps.
Twist's page shows a single $6 rate. Google's list price includes Gmail, Drive and Meet, and Google advertises introductory discounts on top; the table uses regular prices.
Pumble
Best for: the lowest price for Slack-style chat.
Where it wins: Pro is about a third of Slack Pro per seat, and Free keeps unlimited users and history. Business adds 5 free single-channel guests per paid seat and group calls for up to 100.
Watch-outs: a smaller app directory than Slack, and no Slack Connect for channels shared with other companies.
Price: Free for unlimited users; Pro is $2.49 per seat per month billed annually ($2.99 monthly) (pumble.com/pricing). Business is $3.99 billed annually ($4.99 monthly).
Chanty
Best for: teams that want built-in tasks with chat.
Where it wins: Business is $3 per user per month billed annually, with unlimited group audio and video calls and built-in tasks.
Watch-outs: Enterprise pricing is through sales, and the integration list is short next to Slack’s.
Price: Free for up to 5 members; Business is $3 per user per month billed annually ($4 monthly) (chanty.com/pricing).
Microsoft Teams Essentials
Best for: teams that want meetings and chat at a low per-seat price.
Where it wins: a low per-user price, with meetings built in; if you already pay for Microsoft 365, Teams may already be included.
Watch-outs: Essentials is built around meetings, and chat works differently from Slack’s channels and threads.
Price: Teams Essentials is $4.00 per user per month, paid yearly (Teams Essentials).
Twist
Best for: async teams that want fewer, longer threads.
Where it wins: one flat plan with full history and unlimited integrations.
Watch-outs: it is built for async discussion, so it suits teams that want less real-time chat, not a Slack lookalike.
Price: Free shows 1 month of messages and comments; Unlimited is $6 per user per month, the only rate the page shows (twist.com/pricing).
Zulip
Best for: async teams, and teams that could self-host.
Where it wins: Cloud Standard costs less than Slack Pro, and self-hosting is free. Open-source projects and many non-profits get Standard for free.
Watch-outs: topics take a week or two to get used to, and bots work through the API.
Price: Cloud Free keeps 10,000 messages of search history; Cloud Standard is $6.67 per user per month billed annually ($8 monthly). Self-hosting is free, with paid support plans (zulip.com/plans).
Google Workspace
Best for: teams that would also replace their email and docs.
Where it wins: Business Starter costs a little less than Slack Pro and includes Gmail, Drive and Meet, so it can replace more than one bill.
Watch-outs: the list-price savings over Slack Pro are small, Gemini in Chat starts at Business Standard, and Google lists its introductory discounts separately from regular prices.
Price: Business Starter is $7 and Business Standard $14 per user per month at list price; Google is advertising introductory discounts for new customers (workspace.google.com/pricing).
Ando
Best for: teams that would pay for chat where AI agents are members, not to save money.
Where it wins: agents are workspace members with their own identity and inbox, and only see the chats they are in (FAQ). Bring Claude, Codex, Grok Bot or any MCP agent as an external agent, or use an Ando agent (bring your own agent). Pricing is per human seat, and Ando's stated approach is not to meter agent participation (FAQ). Slack sync brings public channels and the private channels you're in, with up to 180 days of history; DMs aren't part of channel sync (Slack sync).
Watch-outs: if cutting your Slack bill is the goal, Ando isn't the answer: its rates aren't published, and Pumble, Chanty and Teams Essentials all publish lower per-seat prices than Slack. Access is by request.
Price: per human seat; rates aren't published yet (pricing philosophy). Starting a new company and moving off iMessage? We'll onboard you in under 24 hours (FAQ).
When Slack is worth what it costs
- Your clients or partners work with you in Slack Connect channels.
- You depend on apps that only exist for Slack.
- Moving would cost more in lost time than the yearly difference.
Before you switch, check whether your Slack bill is for people who rarely use it, and read how to migrate from Slack without losing context.
