"FAQ answered every objection before checkout."
Regular expression Denial of Service from catastrophic backtracking; see OWASP ReDoS guidance.
Notes cover JavaScript/ECMAScript, Python, Go, PCRE, and Rust differences at a high level.
No. Heuristics catch common patterns; novel attacks may be missed.
Explicit Demo returns labelled results without live AI.
It suggests safer patterns and notes; you decide what to ship.

Yes. Self-serve plans cancel anytime; access continues until period end.
No. Start with email signup, then upgrade when ready.
No for Free/Pro. AI runs are included in your plan (fair use) via our platform key. Enterprise can optionally bring your own OpenAI key (BYOK) — configure it at /settings (key stays server-side only).
Pro includes about 300 AI generations/month (and a daily cap) on gpt-4o-mini. If you hit the fair-use limit, Studio returns a mock/demo result until the daily or monthly reset — or upgrade / use Enterprise BYOK for heavier volume.
Payments are processed by Waffo Pancake (merchant of record).
