A private Slack alternative: what to look for in 2026

Slack popularised the idea that a company should have one place to talk. That part was right. But a decade on, a lot of teams are quietly looking for the exit — not because chat is a bad idea, but because the specific trade-offs of the big platforms have drifted away from what a small, focused team needs. If you're searching for an alternative to Slack, this guide covers the questions worth asking before you migrate.

Why teams start looking for a Slack alternative

The reasons are remarkably consistent across the teams we talk to:

• Cost that scales the wrong way. Per-seat pricing means your bill grows with headcount even though most people use a fraction of the features.
• Message history held hostage. On free plans, older messages disappear or get paywalled — your own conversations, gated behind an upgrade.
• Noise by default. Endless channels, threads, and notifications turn a tool that was meant to focus a team into a second inbox to manage.
• Privacy and data residency. For many teams it isn't clear who can read what, where it's stored, or what happens to it. That's a growing problem, not a shrinking one.

What to look for in a Slack alternative

A good replacement isn't the one with the longest feature list. It's the one whose defaults match how your team actually works. We'd weigh these:

1. Privacy you can explain in one sentence

You should be able to say plainly who can read your messages. The strongest answer is end-to-end encryption, where only the people in your workspace hold the keys — not the vendor. At minimum, look for encryption in transit and at rest, and a privacy policy written in words you can actually parse.

2. A workspace your company owns

Look for a clear, per-company workspace — its own space, its own URL, no public feed and no strangers wandering in. Communication is internal; the product should treat it that way.

3. Calm by default

The best tools are quietly alive — presence, typing, reactions, voice notes — without turning every channel into a firehose. Stories and lightweight updates can replace a surprising number of "quick" channel pings.

4. Real native apps

A chat tool lives on your dock and in your pocket all day. Native iOS and macOS apps — not a web page in a wrapper — mean real notifications, real keyboard shortcuts, and lower battery and memory cost. It's the difference you feel by 4pm.

5. Pricing that doesn't punish growth

Favor simple, flat pricing with no "tiers within tiers," and a genuinely useful free plan for small teams. You shouldn't need a spreadsheet to predict next month's bill.

How Interkom approaches it

Interkom is a private social network for your company — built from the start as a calmer, more private Slack alternative. The short version:

• Private by design. Messages and files are end-to-end encrypted, workspace-scoped, with no public feed.
• The essentials, done well. Channels, direct messages, rooms, search, files, reactions, presence and voice notes.
• Stories for teams. 24-hour, workspace-only updates — a lighter way to share progress than yet another channel.
• Native everywhere. Real iOS and macOS apps, plus the web.
• Fair, flat pricing. Free for small teams; one simple paid plan after that.
