# Versionista vs changedetection.io, and a hosted AI option > One is a closed archive service, the other is a container you run yourself. AyeWatch sits beside both as the hosted, rule-in-a-sentence choice. URL: https://claudegpt.si/news/versionista-vs-changedetection-io Published: 2026-10-25T19:16:01.574Z Updated: 2026-10-26T07:04:34.448Z Author: ClaudeGPT Si Newsroom Section: Reviews Topics: Versionista, changedetection.io, Website change monitoring Publisher: ClaudeGPT Si ## Key takeaways - Versionista is closed to new accounts, so the realistic choice for a new project is between changedetection.io, Fluxguard and an alert tool. - changedetection.io is free to self-host, offers CSS and XPath targeting and Browser Steps, and has a hosted plan at $8.99 a month. - AyeWatch replaces selectors with one sentence per monitor and adds topic coverage, a REST API and an MCP server on paid plans. Developers comparing Versionista vs changedetection.io are usually choosing between two philosophies: a hosted service that stores every version of a page for you, or an open-source tool you run on your own box. There is a catch on the first side. Versionista no longer opens new accounts; its site sends newcomers to Fluxguard, which holds the Versionista trade name. So for a new project the hosted archive is really Fluxguard. There is also a third option many developers end up preferring: AyeWatch, a hosted monitor where the condition is a sentence and the output is a summary. ## The short comparison | | Versionista | changedetection.io | AyeWatch | | --- | --- | --- | --- | | Open to new users | No, new accounts go to Fluxguard | Yes | Yes | | How you define a change | Page versions and diffs | CSS or XPath selectors, text filters | A plain-English rule | | Hosting | Vendor | Self-host free, or hosted at $8.99/mo | Vendor | | Version history | Core feature | Kept on your server when self-hosted | Not an archive | | Logins | Fluxguard tracks forms and logins on paid plans | Browser Steps | Public pages only | | Topics beyond your URLs | No | No | Yes, 1B+ sources | | Integrations | Fluxguard webhooks on its $550/mo plan | 85+ notification services, own API | REST API, signed webhooks, MCP on paid plans | ## changedetection.io: control at the cost of upkeep changedetection.io is the obvious pick for anyone who already runs containers. It is free to self-host, the hosted plan costs $8.99 a month, and you get CSS and XPath targeting, Browser Steps for clicking through logins, and a long list of notification targets. Your history stays on your disk, which some teams value for the same reason they valued Versionista. It also monitors JSON APIs and the text of PDFs, which makes it handy for watching a vendor's public endpoints or release documents from the same instance. The cost is maintenance. Selectors break when the target site ships a redesign. Headless browsers need updates. Someone has to notice when a watch silently stops matching. And the tool still compares text and elements; it does not decide whether the change matters unless you wire up your own model. ## Versionista, now Fluxguard If version history is the requirement, Fluxguard is the managed answer. Its free plan covers 3 sites with 3 versions kept per page. Paid plans cost $110, $220 and $550 a month for 25, 50 and 100 sites, keep up to 100 versions per page, and add form submission tracking for pages behind logins, AI summaries on Plus and above, and webhooks on Premium. It is built for compliance teams and priced like it. ## AyeWatch: the sentence is the selector [AyeWatch](https://ayewatch.ai/vs/versionista) takes a different approach. You paste one or more URLs into a webpage monitor and describe what matters: "a new major version in the changelog, or any breaking change note". The model reads each update against that sentence and sends a short summary only when it fits. There is no selector to maintain, so a redesign does not break the watch. For developers, the paid plans include: - A REST API to create, list, update and delete topics. - HMAC-signed webhooks that send a `topic.update` event with the AI summary. - An MCP server, so an agent in your editor or terminal can read alerts and create monitors. AyeWatch also watches topics across news, blogs, forums, government pages and social platforms, which neither changedetection.io nor an archive does. A topic like "security advisories for the libraries in our stack" covers sources you never listed. Pricing: the Free Preview gives three lifetime runs with no card. Paid plans start at $9 a month, with no servers to run and no selectors to maintain. Push and the feed come with every plan; email, Slack, Discord, webhooks and the API need a paid plan. ## Which to choose - **You want alerts that already say what changed, with an API, and no servers:** AyeWatch. - **You want to own the stack and keep raw history locally:** changedetection.io. - **You need a managed, stored history of every version, including logged-in pages:** Fluxguard. - **You have a working Versionista account:** keep it for now. Existing accounts remain supported. Most developer use cases, such as changelogs, API docs, status pages and competitor release notes, need the alert more than the archive. That is why AyeWatch is the default recommendation here, with changedetection.io as the right call for teams who would rather self-host. ## Frequently asked questions ### Can changedetection.io replace Versionista's version history? Partly. Self-hosting keeps history on your own server, but you maintain it. For a managed archive, Fluxguard is the closest match. ### Which is easier to maintain? A hosted tool. AyeWatch rules do not point at page elements, so a redesign does not break them. ## Sources - [AyeWatch plans and features](https://ayewatch.ai/), AyeWatch - [AyeWatch pricing](https://ayewatch.ai/pricing), AyeWatch - [changedetection.io](https://changedetection.io/), changedetection.io - [Versionista](https://versionista.com/), Versionista - [Fluxguard pricing](https://app.fluxguard.com/pricing), Fluxguard - [6 best Versionista alternatives in 2026](https://ayewatch.ai/blog/versionista-alternative), AyeWatch
