What is RNKFLOW?
RNKFlow (Rank Flow) is a real-time feed aggregator that displays live rankings and shifting attention across multiple technology and science sources, letting users watch stories move up and down as they gain or lose traction. The product collects posts from sources such as Hacker News, arXiv, Product Hunt, Dev.to, and specialist tech outlets and surfaces them in continuously updating ranked feeds organized by category (AI, robotics, security, science, code, etc.). Key features include automatically refreshing, reordering feeds based on rank changes, dark mode, per-category filtering, and the ability to follow multiple source feeds simultaneously so users get a single, dynamic view of what’s trending across communities. RNKFlow also supports keyword alerts and simple email digests, making it useful for researchers, product builders, journalists, and community members who want a low-friction way to monitor emergent stories without manual refreshes or visiting each site separately.
RNKFLOW pricing
Pricing model: Freemium
RNKFlow offers a free tier that requires no account and provides access to live feeds, category filters, dark mode, and viewing a set number of posts (free usage is intended for general discovery). A low-cost Pro tier (noted historically as $5 per month) unlocks additional features such as expanded post limits, multi-feed filters, and advanced alerting options (Pro details indicate more customization and higher limits compared with the free tier). The website presents the Pro plan as affordable and aimed at power users who want higher limits and extra convenience; billing cadence and exact feature-by-feature comparison are shown on the site at purchase time.

Frequently asked questions about RNKFLOW
Do I need an account to use RNKFlow?
No account is required to use the free tier of RNKFlow; you can view live feeds, apply category filters, and use dark mode without creating an account.
What sources does RNKFlow include?
RNKFlow aggregates multiple tech and science sources such as Hacker News, arXiv, Dev.to, Product Hunt, Ars Technica, New Atlas and similar outlets, and organizes their posts into unified, rank-ordered feeds.
How does the live ranking work?
The site continuously refreshes and reorders stories based on each source's ranking signals so posts move up and down in real time as they gain or lose attention.
Can I filter by topic or category?
Yes — RNKFlow provides category filters (for example AI, robotics, security, science, and code) so you can limit the feed to subject areas of interest.
Does RNKFlow send alerts or digests?
RNKFlow supports keyword-based alerts and can deliver simple email digests when items matching your tags appear in the feeds.
What does the Pro plan add?
The Pro plan increases post limits, enables more advanced multi-feed filtering and alerting options, and generally raises usage caps and conveniences beyond the free tier.

The site shows a sizable number of posts at once on the free tier (for browsing context) and the Pro tier raises those limits further, with exact counts indicated in plan details.
Can I follow only one source or mix sources?
You can filter to single sources or combine multiple feeds — RNKFlow is designed to let you focus on one community or observe cross-source trends simultaneously.
Is the service free to try?
