§ Tech.01Replaces
What it replaces
| Concern | SaaS approach | Postgres approach |
|---|---|---|
| Data residency | Vendor-determined region | EU-hosted on bare metal — mathematically enforced GDPR compliance |
| Infrastructure Cost | Exorbitant AWS egress fees | Fixed bare-metal server cost with zero bandwidth penalties |
| Data sovereignty | Data held hostage on vendor clouds | Your proprietary data on your server — you hold the absolute keys |
| Backup | Fragmented per-service backup plans | One unified automated cron job backs up the entire state |
Migrating from managed cloud databases to self-managed Postgres routinely drives up to an 80% reduction in pure infrastructure overhead.
§ Tech.02Pipeline
How STACKD uses it
- Powers the infinitely complex business structures mapped by Payload CMS and Chatwoot's omnichannel inboxes.
- Provides persistent checkpointing for LangGraph, ensuring AI agents never hallucinate or lose state upon restart.
- Eradicates the 'noisy neighbour' syndrome of shared cloud hosting by utilising dedicated NVMe disk I/O throughput.
