None (3) · Client and Matrix server software (Synapse/Dendrite/Conduit) are free and open source; self-host at only your hosting cost, use the free matrix.org homeserver, or buy Element's hosted plans. (1) · Cloud DocSpace Business $20/admin/mo; self-hosted Enterprise license from $1,500 (50 connections) (1) · Commercial/Government/Defense tiers are custom-priced (free self-hosted Community edition available) (1) · Free -- zero extra cost if you already run Nextcloud (e.g. for Office Suite). If not, standing up Nextcloud itself is also a free self-hosted install (see that entry for full pricing/hosting details). (1) · Free and open source (Apache 2.0). Self-host at only your hosting cost, use the free public meet.jit.si instance, or buy 8x8's managed Jitsi as a Service (JaaS) for scale/branding. (1) · Free and open source. Run by the non-profit Tor Project, funded by grants (historically including US-government sources such as the State Department and NRL) plus individual donations. Funding is not control here: the code is public, reproducible, and independently audited. (1) · Free on the public instance (meet.jit.si) or self-hosted at no licensing cost (Apache 2.0); managed hosting via 8x8 JaaS from $0.35/monthly active user, or $99+/mo (1) · Free tier covers unlimited passwords/devices for individuals; Teams $4/user/mo, Enterprise $6/user/mo (open-source server, self-hosting available) (1) · Free, no ads, no paid tiers. Run by the Signal Foundation, a US 501(c)(3) nonprofit funded by grants and donations; by charter it cannot be acquired. (1) · Professional $10/user/mo; Enterprise custom pricing (self-hosted free tier available) (1) · Self-hosted is free (single user/accountant); Cloud-hosted plans $12-218/mo (1) · Self-hosted is free, no user limit. Enterprise support from EUR 67.89/user/yr (100-user minimum). Nextcloud One managed hosting ~EUR 13-15/user/mo. (1) · Software is free; self-host on existing infra, or managed CiviCRM hosting from roughly $10-100/mo depending on tier (1)

None (6) · Doikayt's own self-hosted MediaWiki stack: Docker Compose infrastructure plus a markdown-to-wikitext content pipeline for authoring and deploying wiki pages (this wiki is built with it). (1) · End-to-end encrypted 1:1 and group messaging, plus voice/video calls, built on the audited Signal Protocol (Double Ratchet + X3DH). ~40M monthly users. Registration requires a phone number; usernames (added 2024) let you start chats without sharing it. (1) · End-to-end encrypted chat on the Matrix open standard. Anyone can run a homeserver and servers federate like email; Element is the reference client. 115M+ addressable accounts, with bridges to Signal, Telegram, WhatsApp and others. (1) · MIT-licensed, self-hostable team chat with channels, voice/video, and broad integration support. Its omnichannel inbox unifies live chat, email, WhatsApp, and Telegram into one agent queue -- useful if you also want to replace a separate customer-support tool, not just internal chat. (1) · Nonprofit, volunteer-run wiki hosting platform that provides free MediaWiki instances with a wide range of pre-installed extensions. (1) · Open-source CRM purpose-built for nonprofits and advocacy groups -- donor tracking, campaign management, event registration, and membership -- rather than a generic sales CRM repurposed for fundraising. Integrates as a plugin into WordPress, Drupal, or Joomla. (1) · Open-source password manager: unlimited passwords and devices on the free tier, cross-platform sync, autofill. Officially self-hostable, and the community-run Vaultwarden server is a lightweight alternative implementation for orgs that want to run it themselves. (1) · Open-source video conferencing usable instantly with no account via the free public instance, or self-hosted for full control over data and infrastructure. (1) · Self-hostable double-entry accounting: invoicing, online payments, expense tracking, multi-currency, unlimited bank/cash accounts. The free self-hosted tier is limited to one user and one accountant -- fine for a single bookkeeper, not for a team that needs shared access. (1) · Self-hostable, MIT-licensed team chat closely modeled on Slack's channel-based UX -- includes a Slack export/import path to ease migration. Free self-hosted tier runs indefinitely with no per-seat licensing cost; paid tiers add SSO, compliance exports, and HIPAA/FedRAMP-aligned deployment options. (1)

None (10) · Even the self-hosted install requires an API key that calls home to Akaunting's servers to validate your license tier -- worth knowing if full data sovereignty (no external dependency at all) is a hard requirement, since this isn't quite that despite being open source. (1) · Fewer native integrations than Slack out of the box -- most third-party connections go through incoming/outgoing webhooks rather than a marketplace, so budget some setup time. Good fit for teams that want a near drop-in Slack replacement and value Go-based, ops-friendly self-hosting. (1) · Has the most GitHub momentum of the self-hosted Slack alternatives (~45k stars). The free Community edition covers most day-to-day needs; exceeding Starter-plan limits blocks adding new users but does not lock you out of existing data. (1) · See https://www.mediawiki.org/wiki/Miraheze for an overview of available extensions and account setup. No cost, donation-supported; account required to create a new wiki. (1) · See the repo README for local setup and deployment instructions. (1) · Syncs with any CalDAV-compatible client (Thunderbird, most phone calendar apps) so people aren't locked into a web UI. (1)

None (13) · Custodial crypto processors like Coinbase Commerce and BitPay: they take crypto but hold funds and impose KYC, reintroducing exactly the operator-freeze risk that self-custody removes. If the goal is deplatform resistance, a custodial crypto gateway gives up the main advantage. (1) · Relying on the public matrix.org homeserver reintroduces an operator/jurisdiction -- self-host to get the benefit. Discord and Slack are centralized and not end-to-end encrypted. (1) · WhatsApp (uses the Signal protocol but is Meta-owned and harvests metadata) and Telegram (chats are not end-to-end encrypted by default, weaker crypto). (1)
