The 2026 stack we use, end-to-end: PHP 8.3 + Laravel 11 for custom apps, Drupal 10 for content-heavy sites, WordPress 6.7 with a custom theme for marketing. Postgres for everything new, MySQL for inherited. Redis for cache + queues. Cloudflare in front. Restic for off-site backups. Linux on Hetzner or AWS depending on data-residency requirements.
What we rejected and why: Bun (too new, too few production datapoints), edge databases (the consistency story still isn't there for our workloads), most AI-coding-assistant tools beyond Copilot (the time saved on the easy stuff is being lost on debugging the hard stuff).
The new bet: SQLite for small internal tools. Litestream for replication. Cuts hosting cost on those tools by an order of magnitude and reduces the operational surface to a single file. So far we've shipped four of these. None have hit a wall.
