Tools: Self-Hosted Observability: $20/month vs $800/month

The SaaS Quote (Real Numbers) ## The Self-Hosted Stack ## What We Actually Run ## The Hidden Cost: Time ## What You Lose ## What You Gain ## Real Production Numbers ## When SaaS Makes Sense ## Migration Path ## The Realistic Take I run Logtide's production environment, handling 500k logs/day, on a €5.49/month Hetzner server. Datadog quoted me $800/month for the same workload. Here's the honest cost breakdown. I plugged our actual usage into Datadog's pricing calculator: Total: $516/month just for basics. Add retention beyond 15 days? Another $100-200/month. Want custom metrics? More money. Need security monitoring? Keep adding. Real-world Datadog bills easily hit $800-1,200/month for this workload. What you actually need: Infrastructure (Hetzner CX33): Total infrastructure: $9/month Add a domain ($12/year = $1/month) and SSL (Let's Encrypt = free). All-in cost: ~$10-20/month depending on backup strategy. Our production setup on that €5.49 server: Be honest about this part. Total setup: ~10 hours one-time Total ongoing: ~1 hour/month If your time is worth $100/hour: Still way cheaper than Datadog ($9,600/year minimum). The time cost drops significantly after setup. Let's be honest about the downsides. No fancy UI out-of-the-box: Storage with TimescaleDB compression: Datadog for same period: ~$4,800 Self-hosting isn't always the answer. If you're on Datadog and curious: Week 1: Run both in parallel Total migration time: ~16 hours spread over 4 weeks. For most small-to-medium deployments, self-hosted wins on cost. Even if setup takes you 40 hours at $100/hour ($4,000), you break even in 6 months. Every year after that is pure savings. But: If you're a 50-person team with unlimited budget, Datadog's polish might be worth it. The UI is genuinely great. The integrations are extensive. The support is responsive. For everyone else? A $20/month VPS does the job. Running Logtide in production? Self-hosting your observability? Drop your setup and costs below. Curious about the setup? Disclaimer: I build Logtide. These are real numbers from our production environment. Your mileage may vary depending on log volume and retention needs.
