Crate	What it does	Version
tower-rate-tier	Tier-based rate limiting for Tower: per-plan limits (free/pro/enterprise), GCRA with per-request cost, in-memory (DashMap) or Redis storage, standard headers
tower-request-guard	One configurable guard instead of 3-4 layers: body size, per-route timeouts, Content-Type, required headers and JSON-bomb protection, with a dry-run LogAndPass mode
vaultic	Secrets manager CLI (see above)

Both Tower crates work with Axum, Hyper, Tonic and any Tower service.

Self-hosted and desktop electronic invoicing for Spanish businesses, compliant with VeriFactu (AEAT, the Spanish tax agency).
