Highlights

coregex — 3-3000x Faster Regex

Cross-language benchmarks on 6MB input (source):

Pattern Go stdlib coregex Rust regex vs stdlib
Suffix .*\.txt 233 ms 0.98 ms 1.34 ms 238x
Email 260 ms 1.51 ms 1.40 ms 172x
IP validation 494 ms 3.80 ms 12.28 ms 130x
Multi-literal 1436 ms 12.4 ms 4.91 ms 115x

Beats Rust regex on 3 patterns: ip (3.2x), char_class (1.5x), suffix (1.4x). 13 specialized engines, SIMD acceleration, O(n) guaranteed.

relica — Type-Safe SQL

users := relica.Select("id", "name").
    From("users").
    Where(relica.Eq("active", true)).
    OrderBy("created_at DESC").
    Limit(10)

Advanced features: JOINs, subqueries, CTEs, window functions. 3x faster batch operations.

fursy — Modern HTTP Router

r := fursy.New()
r.Get("/users/{id}", handlers.GetUser)  // Type-safe params
// Auto-generates OpenAPI 3.1 spec

RFC 9457 errors, built-in validation, minimal dependencies.

Philosophy

  • Zero CGO — Simple go build, no C compiler needed
  • Minimal Dependencies — Only what's absolutely necessary
  • Production-Grade — Battle-tested, well-documented, maintained
  • Go 1.25+ — Modern Go features, generics where useful
