What It Costs to Run 4 Apps on My Own Servers

A solo founder runs four paid products - Hydrafetch, DataHyena, CatchIntent and Eternal Vault - on one self-managed server for about $45 per month: $40 for 12 dedicated CPU cores, 32 GB of memory and 1 TB of NVMe storage, plus a few dollars for off-site backups. The same mix of web services, workers, databases and Redis is estimated to cost $360-$960 monthly on managed platforms, with PostgreSQL especially expensive as data and memory needs grow. The savings are substantial, but they come from taking responsibility for the work a hosting provider would otherwise handle.

The setup includes encrypted daily database dumps and continuous point-in-time recovery, tested restores, health-checked deployments with rollback, restricted network access, automatic security updates, monitoring, and server configuration maintained as Ansible code. A real migration from backups confirmed the recovery process. Past failures also exposed the risks: unapplied PostgreSQL tuning silently slowed queries, restarting a shared proxy briefly took all four apps offline, and a stalled deploy blocked later releases. The author’s broader argument is that self-hosting can suit small SaaS businesses whose hosting bills are rising faster than their actual resource use, provided someone can maintain the system. Initial setup took weeks and ongoing care takes an hour or two monthly; teams that value convenience, lack server expertise, or have modest bills should stay managed. The infrastructure can expand to multiple servers and database replicas as demand warrants.
