As answered by people managing Codewars and ActReady.
ActReady's answer:
Next.js, Supabase, Clerk, Stripe, Anthropic Claude API, Vercel.
ActReady's answer:
ActReady is the only EU AI Act compliance platform with a free risk classifier that requires zero signup. Results in 60 seconds. We also generate AI-powered compliance documents tailored to your specific system — not generic templates — and provide a full obligation tracker covering all 11 high-risk AI requirements.
ActReady's answer:
ActReady is faster, cheaper, and more accessible than alternatives. The free classifier needs no account. Paid plans start at €29/month vs competitors charging €39+. Documents are AI-generated using Claude (Anthropic) based on your system details, not fill-in-the-blank templates. We also include a GDPR/ISO 27001 overlap mapping and one-click audit pack export.
ActReady's answer:
Small and mid-size businesses that develop or use AI systems and need to comply with the EU AI Act before the August 2, 2026 deadline. Particularly SaaS companies, HR tech providers, and any business using AI for decisions that affect EU users.
ActReady's answer:
The EU AI Act is the most significant AI regulation in history and most SMBs have no idea it applies to them. Compliance consulting costs €50,000+. We built ActReady to make compliance accessible — starting completely free.
