What are the best Discord alternatives in 2026?

Published 2026-09-29 · Researched and price-checked on official sources

Discord alternatives in 2026 split into two camps: free encrypted community apps like Armada, and paid work chat like Zulip Cloud Standard at $6.67 per user per month billed annually or Slack Pro at $7.25. Armada is free, open source under AGPL-3.0, and still in open beta ahead of v1.0.

Key facts

What matters

Armada is free and open source under AGPL-3.0 with no ads and no paid tier, per its own FAQ; it is in open beta ahead of v1.0 and has no iOS app yet.
Self-hosted Zulip and Element Server Suite Community carry no licence fee, while Zulip Cloud Standard is $6.67 per user per month billed annually ($8 billed monthly).
Mattermost no longer publishes per-seat prices: its pricing page lists Professional, Enterprise and Enterprise Advanced as contact-sales, plus a free limited-use Enterprise Advanced edition for evaluation.
Bridging a Discord channel into Armada removes end-to-end encryption for that channel, because every message is mirrored back to Discord in plaintext.
Slack's free plan keeps 90 days of message history; Pro is $7.25 per user per month when paying annually, and Business+ is $15.

What counts as a Discord alternative in 2026?

A Discord alternative is any chat app that puts a community into servers, channels and voice rooms without running on Discord's own infrastructure. The products on the market fall into three groups, and the group you choose decides what you are actually trading away.

Encrypted community apps (Armada, Element on Matrix, Flotilla): messages are encrypted and the design spreads control across servers rather than one company.
Open source Discord clones (Stoat, formerly Revolt, plus smaller projects such as Fluxer and Nerimity): the interface and features feel like Discord, but text chat is not end-to-end encrypted.
Work chat (Slack, Zulip, Mattermost): built for paid teams, with per-seat pricing, admin controls and compliance features a hobby server will never use.

Two caveats before the comparison. End-to-end encryption on Discord covers calls, not text, according to Soapbox's comparison of the field; Soapbox makes Armada, so treat that as a vendor's position rather than a neutral audit. And open source is not the same as free to reuse: Stoat's repository carries an AGPL-3.0 licence with a per-crate exception written into the file header, which is why GitHub reports its licence as "Other" instead of AGPL-3.0.

Which Discord alternative is cheapest for a community?

For a community rather than a company, the licence fee is usually zero. Armada has no paid tier, Stoat is free, Zulip's self-hosted edition is free, and Element's Server Suite Community distribution is free of charge under AGPL. The line item appears when you buy hosted work chat or a managed cloud plan.

Zulip Cloud Standard is $6.67 per user per month billed annually, or $8 billed monthly; Standard Plus is $10 annually and $12 monthly with a 10-user minimum. Slack Pro is $7.25 per user per month when paying annually ($8.75 monthly), and Business+ is $15 annually ($18 monthly), with the free plan capped at 90 days of message history. Both figures were read off Zulip's and Slack's own pricing pages on September 29, 2026.

Mattermost moved the other way and stopped publishing per-seat numbers: its pricing page now lists Professional, Enterprise and Enterprise Advanced behind "Contact Sales", "Get Pricing" and "Request Quote" buttons, plus a free limited-use Enterprise Advanced edition for technical evaluation. Element lists Enterprise Server Suite Pro as priced per seat per month without a figure, and its air-gapped tier as priced per deployment.

What Armada actually is

Armada is an open source, end-to-end encrypted chat app built on Nostr by Soapbox. Communities are spread across several relays instead of one corporate server, an account is a cryptographic key instead of an email or phone number, and the app is free under AGPL-3.0 with no ads and no paid tier, according to its own FAQ. It speaks the Concord and NIP-29 community formats and can join Buzz communities, so a Nostr key carries across other clients in that ecosystem.

It is also openly unfinished. Armada is in open beta ahead of its v1.0 release, with new releases landing almost daily by the vendor's account. Native apps exist for Android, macOS, Linux and Windows. There is no iOS app yet, so iPhone users are pointed at the web app at armada.buzz. Voice and video calls, encrypted direct messages and communities all work in the beta, which is a different maturity level from a decade-old platform.

Self-hosting is where the real cost sits

The free self-hostable options differ in how much of the stack you have to run. Zulip and Element both ship supported self-hosted editions at no licence cost, and Mattermost still offers a self-hosted free edition. Armada splits into three separately self-hostable pieces: the web client, a relay that stores encrypted messages, and a separate voice server built on LiveKit. Its self-hosting guide walks through each one.

What that costs is mostly the server. RackNerd's KVM VPS plans start at $2.24 per month on its homepage as of September 29, 2026, which covers a small community's client and relay comfortably; voice is the piece to size carefully because calls are routed through their own LiveKit box. Put that next to Slack Pro at $7.25 per user per month: a 10-person team on annual billing pays $72.50 per month, while a self-hosted relay for the same group starts around $2.24. The trade is administrative work and no support contract against a predictable monthly bill.

Who should switch, and who should stay

Switch if your community lives in one server that a single company can disable, and encryption of text messages matters to you.
Switch if policy or client work requires your messages to sit on hardware you control: Zulip, Mattermost and Element all self-host today, and Armada's relays do too.
Stay on Discord if your group depends on network effects, the bot ecosystem, or a friend network that will not install another app.
Pay for work chat if you need admin controls and a support contract. Mattermost's free offerings come with community support only, per its pricing page, and its paid tiers are where SLAs start.

The catches the vendor pages play down

Armada and its Discord bridge are both in open beta ahead of v1.0, so the vendor itself warns about occasional rough edges.
There is no iOS app yet. Android, macOS, Linux and Windows have native builds; iPhone does not.
Bridging a channel to Discord removes end-to-end encryption for that channel, because every message is mirrored back to Discord in plaintext. Channels you import without a bridge stay encrypted.
Stoat, Fluxer and Nerimity do not federate, so a self-hosted instance is an island rather than part of one network, as Soapbox's comparison notes.
Slack's free plan drops messages after 90 days; Mattermost's free edition is a limited-use Enterprise Advanced evaluation; Element's enterprise tier needs a quote before you can price it.
Stoat's licence is AGPL-3.0 with an exception for crates that ship their own licence file. Read it before you plan a fork, because GitHub's licence badge reads "Other".

Migrating a Discord server without losing your history

Armada ships a Discord import tool that turns a server you administer into an Armada community. You need a Discord account with Manage Server rights on that server, a free Nostr login at armada.buzz, and about ten minutes. No bot tokens and no export files are involved.

Channels, roles, custom emoji and up to 10,000 messages of history per channel come across with their original timestamps and authors. Permissions that have no Armada equivalent are listed as dropped next to each role. A live two-way bridge can mirror selected channels while members move at their own pace, at the cost of encryption on those channels. If the import stops partway, retrying resumes where it left off instead of starting over. Members who never migrate keep using Discord exactly as before.
