Frequently Asked Questions

Are all tools really free with no limits?
Yes. Every tool — including the 10 AI-powered ones — is free to use with no account. AI tools have a rate limit of 10 requests/minute per IP to prevent abuse, but there's no daily cap for normal usage.
Do you store my data?
No. All non-AI tools run entirely in your browser — nothing leaves your device. For AI tools, your input is sent to our API to generate a response, but we do not log, store, or sell your inputs.
Do you show ads right now?
Not currently. Google AdSense is implemented in the site, but it has not been activated yet. Right now, CodeKitLab is supported by cross-promotion and occasional affiliate links. If ads are enabled later, we will keep them limited and clearly separated from the tools.
Can I use an ad blocker?
Yes. We never gate tools behind disabling your ad blocker. If you block ads, the tools still work perfectly. We'd appreciate it if you whitelist us — it genuinely helps keep the site running — but it's your call.
What AI model powers the AI tools?
We use a waterfall: Google Gemini 2.0 Flash Lite → Groq Llama 3.3 70B → Ollama Mistral (local fallback). This gives high availability and fast responses at zero cost to you.
Who is behind CodeKitLab?
CodeKitLab is a product of Syscobyte AB, a Swedish software company. We also build AlertsDock, an uptime monitoring service for APIs and cron jobs.
Will it stay free?
Yes. The ad-supported free model is our long-term business model, not a growth hack. We have no plans to add a paywall or restrict any existing tools.
