Overview
SupaCove and WordPress Speed Optimization Service (WSOS) are two products that address very different problems. SupaCove is a self-hosted PostgreSQL backup tool that focuses on data safety, encryption, and restore reliability. WSOS is a service that optimizes WordPress sites for speed, targeting Core Web Vitals and overall performance.
SupaCove is designed for developers and database administrators who manage PostgreSQL databases and want full control over their backups. It uses pg_dump to export data, encrypts it with age, and stores it in S3-compatible object storage. The entire process is transparent, with failures clearly marked, and restores do not depend on the original instance.
WSOS, on the other hand, is a done-for-you service for WordPress site owners who want to improve loading times, interactivity, and visual stability. It includes a free speed audit, a full optimization pass using Cloudflare edge caching, FlyingPress, next-gen image formats, and code minification, followed by a before/after report with real metrics.

WSOS charges a one-time fee of $239 per site. There is no upfront payment; you only pay after the optimization is complete and you have seen the results. A free speed audit is included before you commit.
