Built Right

Security and performance baked in from the start, not bolted on after.

Rate Limiting

IP-based rate limiting on form submissions (3/hour) and login attempts (5/15min). Automatic cleanup of old entries.

Spam Prevention

Honeypot field traps bots silently. No CAPTCHAs, no friction for real users. Bots get a fake success page.

Session Security

Cryptographically random session tokens. HttpOnly, Secure, SameSite cookies. 30-day sessions with server-side validation.

SQLite + WAL

Write-Ahead Logging for concurrent reads during writes. Single-file database. No external database server needed.

~2MB Binary

Compiles to a single static binary. No runtime dependencies. Memory usage under 10MB. Starts in milliseconds.

SEO Ready

Dynamic robots.txt, sitemap.xml, security.txt. Structured data (JSON-LD). Open Graph and Twitter Card meta tags.

AI-Agent-First Codebase

Every file, function, and convention is designed so an AI coding agent can understand, modify, and ship changes on the first try.

CLAUDE.md Context

Single context document with architecture, routes, schema, env vars, and conventions. Any agent can onboard in one read.

Small Focused Files

Go files under 250 lines, CSS files under 450 lines. Every file fits in a single context window with room to spare.

Clear Boundaries

No circular dependencies. Each package has one job. Handlers, models, database, templates — all separate.

Test Coverage

Run make test after every change. Integration tests for handlers, unit tests for validation and rate limiting.

Zero Magic

No frameworks, no codegen, no ORM, no middleware chains. Just Go stdlib, SQL strings, and HTML templates.

Consistent Patterns

Every handler checks auth the same way. Every template uses the same data flow. Learn one pattern, know them all.
