Pay with a card, PayPal, bank transfer, cash mailed in an envelope, or cryptocurrency (incl. Monero). · 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). · Free (40-min cap on group calls, 100 participants); Pro from $14.16/user/mo (annual) / $16.99 (monthly), removes the time cap · Free account, no monthly fee on the entry (Standard) tier; pay-as-you-go per-transaction (roughly 1% with a per-payment cap -- verify current rates). US ACH is capped at $5,000 per transaction; $5 per chargeback above 15 in a month. · 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. · 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. · Free events are always free. Paid tickets: ~3.7%+$1.79/ticket plus 2.9% payment processing, no fee cap. Pro email tiers $15-100/mo (nonprofits get 50% off after verification). · 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 · Free tier covers unlimited passwords/devices for individuals; Teams $4/user/mo, Enterprise $6/user/mo (open-source server, self-hosting available) · 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. · 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. · 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. · No platform fee -- 100% of funds raised go to the cause, minus standard payment processing · paid plans from $5/mo · Platform fee 8-12% of earnings by tier (Lite/Pro/Premium), plus roughly 2.9-5% payment processing; fee structure was revised in a September 2024 policy overhaul · Professional $10/user/mo; Enterprise custom pricing (self-hosted free tier available) · Self-hosted is free (single user/accountant); Cloud-hosted plans $12-218/mo · Self-hosted is free, no user limit.

None (6) · 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) · Event listing, promotion, and ticketing -- event pages, RSVP/ticket sales, and email promotion to an audience list. Free to publish and manage free events with no platform fee; fees only apply to paid ticket sales. (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-oriented crowdfunding platform charging no platform fee, explicitly open to individuals, social enterprises, and unregistered community groups, not just registered charities. Scale (per Chuffed's own reporting): 50,000+ organizers, 2.5M+ supporters, $275M+ raised to date. (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) · Zero-fee fundraising, ticketing, and membership platform for nonprofits. Scale (per Zeffy's own reporting): 100,000+ nonprofits, $2B+ raised to date. (1)

None (12) · 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) · Syncs with any CalDAV-compatible client (Thunderbird, most phone calendar apps) so people aren't locked into a web UI. (1) · The free plan supports up to 20 email alert recipients — sufficient for most small organizations. Webhook triggers allow integration with custom scripts or chat tools on status changes. (1)

None (15) · 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)
