Plain vs Slack.
Slack is the default place engineering teams talk, and the place that conversation goes to disappear. The thread deciding the architecture is three scrolls and one paid search tier away from the code it decided. Plain Chat attaches channels and threads to the issue, PR, or doc they are about, in the same search index as everything else.
// Coverage
Slack does one job. Plain is the whole setup.
Seven surfaces every software team ends up paying for, one way or another. Here is what each product actually covers.

Slack fully covers 1 of the seven surfaces. Plain covers all seven on one seat.
// Credit where due
Where Slack is genuinely good.
- It is the network. Customers, communities, and half your integrations are already on Slack.
- The app ecosystem and platform APIs are the most mature in team chat.
- Huddles and the day-to-day messaging experience are polished and familiar to everyone you will ever hire.
The catch.
Slack is where decisions are made and then lost. The discussion about the bug lives a copy-paste away from the bug, the deploy thread is unfindable a week later, and the bot posting CI failures is one more integration to maintain. In Plain the conversation is attached to the thing it is about, agents reply inline with full context, and chat history is searchable next to your code and issues.
// Pricing
One seat price vs a stack of them.
Slack
$7.25/ user / mo
Covers team chat. The other surfaces are other tools, other invoices.
Slack Pro, annual billing. Business+ is $12.50. The rest of the stack is other vendors.
Plain Pro
$24/ user / mo
Code, issues, docs, chat, CI, packages, and AI agents on every seat. One bill, one search index, one source of truth.
// FAQ
Common questions.
- Is Plain a Slack alternative?
- Yes. Plain Chat has channels, threads, and DMs like Slack, with one difference that matters: conversations attach to the issues, PRs, and docs they are about, and they are searchable in the same index as your code.
- Can I import Slack history into Plain?
- Yes. Plain imports Slack channel history and files via the standard export, so the archive survives the move.
- How does Plain pricing compare to Slack?
- Slack Pro is $7.25 per user per month for chat alone. Plain Pro is $24 and includes chat plus the Git host, tracker, docs, CI, and registry it would otherwise sit beside.
