None · Choose the region closest to your primary users to minimize latency. Enable automatic backups ($1.20/month at the entry tier) from the start — restoring from a snapshot is far easier than rebuilding from scratch. · 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. · Explore active campaigns from the Campaigns tab. Mobile apps available on iOS (App Store) and Android (Google Play). · 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. · 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. · Registration: no nonprofit status or business registration required -- sign up and start collecting tips/memberships as an individual or org account. · Registration: no nonprofit status or business registration required to sign up. · 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. · See the repo README for local setup and deployment instructions. · Syncs with any CalDAV-compatible client (Thunderbird, most phone calendar apps) so people aren't locked into a web UI. · 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. · Use Board view for kanban-style tracking across teams. Guest access is available on paid plans for external collaborators. · 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. · Other
