--- title: "The European Slack alternative (2026) | mssgs" description: "Looking for a Slack alternative? mssgs has channels, calls, integrations and your full history, from a Dutch company with your data in the EU. Free to start." canonical: https://mss.gs/en/slack-alternative language: en --- # The European alternative to Slack Channels, DMs, calls and integrations for your team, with your full history kept and your data in the EU. No 90-day limit, no price per seat for the basics. ## mssgs as a Slack alternative mssgs is a European alternative to Slack for small teams, agencies, clubs and organisations. It has channels, direct messages, voice and video calls with screen sharing, webhooks, /command triggers and bots, and keeps your complete message history searchable. The difference: mssgs is made by a Dutch company, stores everything in the EU with a Dutch hosting provider, end-to-end encrypts one-to-one chats, and channels, DMs and calls are free for everyone. Large companies that need SSO, compliance exports or Slack Connect are better served by Slack. Made by RUAL, the Netherlands (since 2009) Data stored In the EU, with a Dutch hosting provider Price Free to start, no credit card History Complete and searchable Apps iOS, Android, Windows, macOS, Linux, web GDPR Data processing agreement available Comparison checked on 27 September 2026. ## Slack and mssgs, side by side What your team uses every day, and where the two differ. Green marks the side that is ahead on that row, and we say so when that is Slack. | Feature | Slack | mssgs | | --- | --- | --- | | **Company and data** | | | | Made by | Slack, owned by Salesforce, United States | RUAL, the Netherlands | | Where your data is stored | United States, other regions (including the EU) on higher plans | In the EU on every plan, with a Dutch hosting provider | | End-to-end encrypted chats | No | Yes, one-to-one chats (Signal protocol) | | Self-hosting | No | On request | | **Free plan** | | | | Message history | Last 90 days, data older than a year is deleted | Complete and searchable | | Group calls | No, one-to-one huddles only | Yes, voice channels with camera and screen sharing | | Integrations | Up to 10 apps | Webhooks, /command triggers and bot messages built in | | **Working together** | | | | Channels, DMs, mentions and reactions | Yes | Yes | | Threads | Yes | Replies and quotes in the channel | | Shared channels with other companies | Slack Connect | Invite outside people and limit what they see with roles | | Join only with a company email | Yes | Yes | | App directory | Thousands of apps and Workflow Builder | GitHub, UniFi, webhooks, workflow automations for work accounts | | AI assistants | Slack AI and an official MCP server | MCP built into the desktop app, 127 tools, only the channels you pick | | **Administration and price** | | | | Single sign-on (SAML) | On Business+ and Enterprise | No | | Compliance exports and legal hold | On higher plans | No | | Price | Free with limits, Pro from $7.25 per user per month (billed yearly) | Channels, DMs and calls free for everyone, Premium optional per person | | Apps | Windows, macOS, Linux, iOS, Android, web | Windows, macOS, Linux, iOS, Android, web | Checked on 27 September 2026 against Slack's own pricing and help pages.

Channels, direct messages and calls are free for everyone. [Premium](https://mss.gs/en/credits) is optional, per person, and never renews by itself. ### An American company Slack is owned by Salesforce. Data sits in the United States unless you pay for data residency on a higher plan, and a US company stays within reach of US law such as the CLOUD Act. mssgs is made in the Netherlands, falls under Dutch law and stores everything in the EU on every plan, no American cloud. See [security](https://mss.gs/en/security). ### Nothing end-to-end encrypted Slack does not end-to-end encrypt messages, not even direct messages. One-to-one chats are end-to-end encrypted with the Signal protocol. Everything else is stored encrypted (AES-256) and never used to train AI. ### Group calls behind a paywall Free Slack workspaces only get one-to-one huddles. Group calls need a paid plan. Every community can have voice channels with camera and screen sharing, free. ### Ten apps on the free plan A free Slack workspace can connect at most ten apps and integrations. Incoming [webhooks](https://mss.gs/en/docs/webhooks), /command triggers without code and [bot messages](https://mss.gs/en/docs/bots) are part of every account. ## What Slack still does better mssgs is not built for every company. These are the things Slack does that mssgs does not, so you can decide with your eyes open. - **Threads.** Slack's threaded conversations keep busy channels tidy. - **Slack Connect.** Shared channels with clients and partners in their own workspace. - **Thousands of apps** and Workflow Builder for automations without code. - **Enterprise controls**: single sign-on, SCIM, audit logs, compliance exports and legal hold. - **Guest accounts, canvases and lists** for working with people outside your team. - **Everybody knows it.** Your clients and freelancers are probably already on Slack. ### Stay on Slack if - you are a large company that needs single sign-on and compliance exports - most of your work happens in shared channels with other companies - your workflows depend on specific Slack apps ### Choose mssgs if - you are a small team, agency, association or club - you want a European company and your data in the EU - you do not want a 90-day limit or a price per seat for chatting - you want drop-in voice channels and bots without extra hosting ## Move your team from Slack in three steps The basic setup takes about fifteen minutes. After that it is a matter of inviting your people. ### Create a work account Download mssgs or [open it in your browser](https://mss.gs/app), and pick a work account when you sign up.

For small and medium teams that mostly need channels, direct messages, calls and integrations, mssgs is a strong European choice: it is made by a Dutch company, stores all data in the EU and is free to start. It is listed on eu-alt.eu as a European alternative to Slack. Large enterprises that need single sign-on and compliance exports are still better served by Slack. ### Is there a free Slack alternative without the 90-day limit? Yes. mssgs keeps your complete message history and lets you search all of it, and channels, direct messages and calls are free for everyone. There is no credit card needed to start. ### Is mssgs GDPR compliant? mssgs is a Dutch company, stores all data in the EU with a Dutch hosting provider and does not use American cloud providers. Business customers can get a data processing agreement via [privacy@mss.gs](mailto:privacy@mss.gs). See [security](https://mss.gs/en/security) for the details. ### Can I import my Slack history? There is no automatic import. Export your Slack workspace and get in touch, and we help you plan the move. Most teams start fresh in mssgs and keep the Slack export as an archive. ### How much does mssgs cost compared to Slack? Slack Pro starts at $7.25 per user per month, billed yearly. In mssgs, channels, direct messages and calls are free for everyone. [Premium](https://mss.gs/en/credits) is an optional upgrade per person, paid with credits, that never renews by itself. ### Does mssgs have threads and huddles like Slack? mssgs has replies and quotes inside the channel rather than separate threads. For calls it has voice channels you drop into, with camera and screen sharing, which works like a huddle that is always open. ### Does mssgs support single sign-on? No. You sign in with a code sent to your email, optionally with a password and two-factor authentication through a passkey, an authenticator app, a hardware key or SMS. You can also limit who joins your community to your company email domain. ### Can AI assistants read our channels? Only if you connect one. The [MCP server](https://mss.gs/en/docs/mcp) runs locally in the desktop app, you pick which channels an assistant can see, and every write action is a separate switch. mssgs never uses your messages to train AI. ## Other alternatives ## Give your team a European home Free to start, no credit card.
