Your primary tools will fail. Not might—will. Cloud services go down, APIs break, and sometimes your entire workflow depends on a single platform. The difference between a minor inconvenience and a business-stopping disaster is whether you've already chosen your backups. This isn't about paranoia. It's about knowing exactly what you'll use when Slack, Google Docs, or your project management tool stops responding. We've tested the most practical alternatives that actually work as substitutes, not just pale imitations.
Email and Communication: Proton Mail and Mattermost
When Gmail goes down (and it does), Proton Mail offers a genuinely independent alternative with zero reliance on Google's infrastructure. It's encrypted end-to-end, so you're not just switching providers—you're switching security models. For team chat, Mattermost is self-hosted Slack. That matters: you control the server, the data, and uptime. Most teams don't realize Slack's outages often stem from dependencies on AWS—if AWS has regional issues, Slack might be fine but your integration layer breaks. Mattermost running on your own hardware eliminates that entire failure chain. Setup takes 30 minutes. The catch: you need to maintain it. That's actually the feature.
Document Editing: Standard Notes and Cryptpad
Google Docs outages are rare but devastating when they happen—you can't even see read-only versions during major incidents. Standard Notes syncs locally and works offline. More importantly: it syncs to your own server if you self-host. Cryptpad is collaborative (multiple people editing simultaneously) and runs entirely in the browser with no server-side processing of content. This creates an unusual property: even if Cryptpad's servers have issues, your documents remain accessible in browser cache. That's not a feature you'll find in marketing materials, but it's technically significant. Both handle version history and work across devices without the complexity of maintaining local file sync.
Project Management: Plane and OpenProject
Notion and Asana failures are recoverable but slow—those tools are database-heavy and complex. Plane is lightweight project management that exports cleanly to JSON. OpenProject is enterprise-grade but self-hostable. The real advantage: both use standard data formats. If you need to migrate at 3 AM because your primary tool is down, you're not wrestling with proprietary APIs. You're moving structured data. Keep a weekly export of your current project structure in both tools. This takes five minutes to automate. When your primary tool goes down, your team can continue in the backup without re-entering tasks—just import last week's export and note what changed verbally in the interim.
Code Repositories: Gitea and Sourcehut
GitHub outages are rare enough that most teams don't maintain backups. That's exactly when you need them. Gitea is a lightweight Git service you can self-host on minimal hardware. Sourcehut is a federated alternative that doesn't require hosting—it's maintained infrastructure. Both support mirroring: your repository exists in two places simultaneously. Git itself is your backup system—every clone is a full copy of history. What matters is the metadata: pull requests, issues, CI/CD configuration. Sourcehut stores this in plain text files. Gitea exports it via API. Spend 20 minutes setting up mirror-on-push. Your code survives any single platform failure.
The Immediate Action: Create Your Backup Stack Map
Don't implement everything. Identify your actual critical tools—the ones that, if down for four hours, would stop work. For each, pick one backup. Write down: (1) the tool name, (2) how to access it, (3) how to get your current data into it. Spend 30 minutes this week setting up data export automation or mirroring for your top three critical tools. Test it once. That's enough. Most teams that survive outages aren't running redundant infrastructure—they're running one backup they've actually tested. The ones that fail are running four untested backups they've never opened. One tested backup beats five theoretical ones.
