Best rank tracker for indie hackers

There are roughly 30-50 rank tracking tools in the market, but most cluster into two tiers: enterprise solutions (SEMrush, Ahrefs, Moz) targeting agencies and large companies, and mid-market tools (Rank Tracker, AccuRanker) that still assume you're managing multiple client campaigns. The common pain point is overkill—indie hackers need to monitor 10-50 keywords for their own product, not manage 1,000+ rankings across portfolios. Most existing tools charge $50-300/month minimum, have UI designed for analysts, not makers, and require learning curves that steal shipping time. The actual gap is in the sub-$20/month category with a dead-simple dashboard, API-first design, and integration with tools indie hackers already use (Discord, Slack, Telegram). The opportunity sits at the intersection of affordability and simplicity: a vibecoder building a side project needs notifications when a keyword breaks top 10, not a 47-column spreadsheet. A new entrant should focus on the bottom-of-funnel winner—rank tracking for single projects under 100 keywords—rather than competing on breadth.
