What It Is

100xTools is a collection of Chrome extensions focused on “productivity enhancement.” Based on the website copy, its current core products include TwFollow, TwExportly, and SubShift, covering Twitter/X follower relationship extraction, tweet exporting, and YouTube subscription backup, export, and import, respectively. It is more of a social platform data management toolkit than a traditional developer tool.

Core Features and Ecosystem

TwFollow can extract followers and following lists from any Twitter user; TwExportly supports exporting tweets from any Twitter account and downloading them as CSV/Excel files, making it useful for archiving, spreadsheet analysis, or content migration. SubShift focuses on YouTube subscription management, allowing one-click backup, export, and import of subscriptions, which is helpful for account migration and preventing subscription lists from being lost. The product format is a Chrome extension, and its ecosystem depends on Chrome, Twitter/X, and YouTube. The website’s resources section also mentions Chrome Developer and X Developer Platform, but it does not clarify any deeper integration capabilities.

Pricing and Openness

The website does not disclose specific pricing, plans, free quotas, or payment methods in its main content. The terms only mention possible price changes, refund policies, and liability limits related to user payments. As a result, it is not possible to assess its value-for-money ceiling. On the open-source side, no public repository or license is visible; the terms instead emphasize proprietary rights over the website source code, databases, software, and content, so it should be treated as not publicly open source. Self-hosting, APIs, and SDKs are not mentioned.

Pros and Cons

The main advantage is its clearly defined use cases: social media operations, data archiving, account migration, and research analysis may all require exporting follower lists, tweets, or subscription data. The Chrome extension format also lowers the barrier to entry, while CSV/Excel output makes further processing easier. The downside is that public documentation is thin, with only one-line product descriptions and no detailed explanation of permissions, export fields, rate limits, failure handling, or privacy and security practices. The only support channel currently visible is [email protected], and the service SLA is unclear.

Who It’s For and Access from China

100xTools is suitable for individual creators, social media operators, researchers, and users who need to migrate YouTube/Twitter assets. Access to the 100xTools website itself from mainland China is unclear, but its core functionality depends on Twitter/X, YouTube, and the Chrome extension ecosystem, which are usually restricted in the mainland network environment. In practice, usage can be considered “partially restricted” and may require a proxy environment. Alternatives include official platform data archives, Google Takeout, or automation data tools such as Apify and Phantombuster.
