What It Is

Megalodon (megalodon.jp) is a web snapshot service operated by 株式会社アフィリティー. It positions itself as a “tool for citing web pages.” Users can capture a snapshot of a web page at a specific point in time, then copy the generated URL and use it as a citation link in blogs, forums, and similar contexts.

Core Features and Ecosystem

Based on the crawled content, the service supports searching for and creating snapshots by URL, as well as free keyword search and browsing by date. One practical detail is that when visiting a website in the browser, users can prepend gyo.tc/ to the URL to jump to the snapshot search or capture page, lowering the barrier for ordinary users to save web pages. Its integration model is mainly “copy the link and paste it elsewhere,” which suits content citation and lightweight evidence preservation. However, there is no visible documentation for browser extensions, APIs, SDKs, Webhooks, or bulk archiving.

Openness, Deployment, and Documentation

The content does not state whether it is open source, nor does it offer a self-hosting option. Overall, it appears to be a centralized online service. The terms of service clearly list prohibited activities, deletion rights, disclaimers, and personal information handling: the operator may delete snapshots and comments at its own discretion; when a snapshot is created, the user’s IP address is stored and may be disclosed if the operator deems it necessary. This information is useful for compliance assessment, but for developers, key details such as API documentation, data retention periods, SLA, and rate limits are missing.

Pricing

The page mentions “有料機能,” indicating that paid features exist, but the content does not provide pricing, plans, payment methods, or details on paid benefits. As a result, it is not possible to judge the value for money of any commercial version. If used only for occasional web citations, the free entry point appears straightforward enough. For team archiving, evidence preservation, or automated collection, however, the available information is clearly insufficient.

Pros, Cons, and Who It’s For

Its strengths are a simple workflow, a clearly defined citation use case, and search options by URL, keyword, and date. Its weaknesses include the risk of centralized deletion, opaque paid-feature details, no public API/SDK information, and no evident enterprise-level support. It is better suited to bloggers, forum users, researchers, and general users who need to quickly save web citations. It is less suitable for engineering teams that require auditable, bulk-capable, or self-hosted archiving.

Access from China and Alternatives

The content does not provide information on access from mainland China, network availability, or payment methods, so its availability in China is unknown. Comparable alternatives include Internet Archive Wayback Machine, archive.today, and Perma.cc. If a Chinese-language environment and controlled retention are required, localized screenshot archiving or a self-hosted web archiving solution should also be evaluated.
