5 Self-Hosted Tools to Replace Your SaaS Stack This Month

You’re paying $15,000+ per year for tools that could cost $500 to self-host. Not “someday”—this month. Not with complex migrations—with Docker containers you can spin up in an afternoon.

Here are 5 self-hosted alternatives to replace your most expensive SaaS subscriptions, with deployment guides and honest ROI math.

The SaaS Bill You’re Paying

Typical 20-person team:

• Zoom: $15/seat/month × 20 = $3,600/year
• Slack: $15/seat/month × 20 = $3,600/year
• Google Workspace: $12/seat/month × 20 = $2,880/year
• Trello: $10/seat/month × 20 = $2,400/year
• Notion: $10/seat/month × 20 = $2,400/year

Total: $14,880/year

That’s a car payment. Every year. Forever.

The Self-Hosted Stack

Replace all 5 with open-source alternatives, and your total cost drops to $50/month for a VPS—$600/year. The math: $14,880 → $600. That’s a 96% reduction.

Here’s how to do it.

1. Jitsi Meet (Replaces Zoom)

What it is: Browser-based video conferencing, no client installation required. Think Google Meet, but self-hosted and unlimited duration.

Deployment time: 30 minutes
Difficulty: Easy
Annual cost: $0 (on existing server)

Quick Deploy with Docker

# Create directories
mkdir -p ~/.jitsi-meet-cfg/{web/letsencrypt,transcripts,prosody,jicofo,jvb}

# Run Jitsi Meet
docker run -d --name jitsi-meet \
  -p 80:80 -p 443:443 \
  -v ~/.jitsi-meet-cfg/web:/config \
  -v ~/.jitsi-meet-cfg/letsencrypt:/etc/letsencrypt \
  -e ENABLE_LETSENCRYPT=1 \
  -e LETSENCRYPT_DOMAIN=meet.yourcompany.com \
  -e LETSENCRYPT_EMAIL=admin@yourcompany.com \
  jitsi/docker-jitsi-meet:latest

Your video meetings are now at https://meet.yourcompany.com. No time limits, no per-seat pricing, no “your meeting will end in 40 minutes” warnings.

When to Stick with SaaS

Self-hosting isn’t for everyone. Stick with SaaS if:

• You have no technical staff
• You need 99.99% uptime SLAs
• You’re a 2-person team on free tiers
• You rely on deep SaaS integrations (Salesforce, etc.)

But if you’re paying $15K/year for tools, have a developer who can manage Docker, and want to own your data—self-hosting pays for itself in 2 months.

Next Steps

1. Audit your SaaS bill: Check what you’re actually paying
2. Pick one tool: Start with Jitsi or Mattermost (easiest deployment)
3. Deploy this weekend: 2-4 hours gets you running
4. Migrate over 4 weeks: Don’t try to do everything at once
5. Cancel subscriptions: Keep the $14,280/year

The moat is falling. Your SaaS bill doesn’t have to keep rising.
