$4.99/mo, or $3.99/mo billed annually (free tier available) (1) ·
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) ·
Fee is set by whichever Fiscal Host a collective joins (commonly cited range
roughly 4-10%, some hosts free); Open Collective's own platform software is open source and
does not charge separately from the host's fee (1) ·
Flat EUR 5 / month, no tiers and no discounts for longer commitments. Pay with a card,
PayPal, bank transfer, cash mailed in an envelope, or cryptocurrency (incl. Monero). (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 tier hosts up to 50 participants for 1 hour per call; guests join by link with no
account. Paid Meet Professional raises this to 100 participants and 24-hour calls with recording;
higher Workspace tiers reach 250. Often bundled with the rest of the Proton suite. (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) ·
Genuinely free tier (unlimited data, no ads, one device, 5 countries). Paid plans add
more countries, up to 10 devices, and streaming/P2P; often bundled with Proton Mail/Drive/Pass. (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 and open source (GPLv2); your only cost is a VPS -- roughly
USD 4-6 / month on a provider like [[Digital Ocean]], or a spare box you already run. (1) ·
Software is free; self-host on existing infra, or managed CiviCRM hosting from
roughly $10-100/mo depending on tier (1) ·
Standard and Pro plans (roughly USD 6-10 / month depending on term). Anonymous signup
returns a random 15-character account ID with no email; pay by card, Monero, Bitcoin, or cash
mailed to Gibraltar. (1)
None (10) ·
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) ·
Privacy-first WireGuard/OpenVPN provider run from Sweden. No email or personal
details at signup -- you get a random account number instead of a username/password. Owned by
Mullvad VPN AB (also behind the Mullvad Browser, built with the Tor Project). (1) ·
Privacy-focused WireGuard/OpenVPN provider operating from Gibraltar under IVPN
Limited since 2009. All client apps are open source under GPLv3. Signup requires no personal
information -- just the generated account ID. (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) ·
WireGuard/OpenVPN provider from Geneva, operated by Proton AG and majority-owned by
the non-profit Proton Foundation. Founded by scientists who met at CERN; same organisation as
Proton Mail. Every client app (Windows, macOS, Linux, Android, iOS) is open source. (1)
None (16) ·
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) ·
Zero-access encryption means Proton cannot read message content or hand
it over even under legal request -- worth flagging for teams handling sensitive
organizing communications. No self-hosting option; mail is hosted on Proton's own
infrastructure in Switzerland. (1)
None (15) ·
Commercial Israeli-owned VPNs (Kape's ExpressVPN / CyberGhost / PIA /
ZenMate, Hola, Hotspot Shield) reintroduce exactly the operator you're trying to remove -- see
[[:Category:VPN]]. (1) ·
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) ·
ExpressVPN, CyberGhost, PIA, and ZenMate are all owned by the
British-Israeli Kape Technologies (now a delisted black box); Hola VPN is Israeli and resold
user bandwidth. See [[:Category:VPN]] for the full ownership picture. (1) ·
Israeli-owned options (Kape's ExpressVPN / CyberGhost / PIA / ZenMate,
Hola VPN, Hotspot Shield via Pango) are rejected on ownership grounds -- see [[:Category:VPN]]. (1) ·
Kape's ExpressVPN / CyberGhost / PIA / ZenMate, Hola VPN, and Hotspot
Shield / Betternet are rejected on ownership grounds -- see [[:Category:VPN]]. (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) ·
Zoom and Google Meet are closed-source and not end-to-end encrypted by
default, with the provider able to access call data. For a fully self-hosted option, Jitsi Meet
on your own server keeps infrastructure in your hands (see [[:Category:Self Hosting]]). (1)
