Common questions

Is changedetection.io (official) safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.70.1) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

AI-powered website change detection — smart alerts and plain-language summaries

Stop drowning in noise. Connect any LLM (OpenAI, Gemini, Anthropic, Ollama and more) and go from _"something changed"_ to _"only the thing you care about changed"_.

AI change detection rules — write a plain-English intent once: _"notify me only when the price drops below $50"_, _"alert me when the item comes back in stock"_, _"ignore navigation and footer changes"_. The AI evaluates every detected diff against your intent and silently suppresses everything irrelevant. Fewer false positives, zero noise.

AI change summaries — instead of staring at a raw diff, your notification reads _"Price dropped from $89.99 to $67.00"_ or _"3 new products added to the listing"_. Works globally or per-watch, with full control over the prompt.

Works with any model you already pay for — GPT-4o-mini and Gemini Flash handle this well at fractions of a cent per check. Or run it entirely locally with Ollama, vLLM, LM Studio, or any OpenAI-compatible self-hosted endpoint — pick the *OpenAI-compatible (vLLM, LM Studio, llama.cpp)* option in the provider dropdown and point it at your server's /v1 URL. Powered by LiteLLM, giving you seamless access to 100+ supported providers and models.

We've got a quick tutorial here - Bring your own LLM/AI Key to changedetection.io for change summaries and triggers.

After Browser Steps have been run, then visit the Visual Selector tab to refine the content you're interested in. Requires Playwright to be enabled.
