Probedex

Probedex is a competitive intelligence tool built specifically for SaaS founders. It lets you scan over 121,000 SaaS domains to find competitors that are actually gaining traffic and revenue, then get a detailed teardown of how they grew. Instead of juggling six different dashboards and spreadsheets, you get a single report that covers traffic sources, SEO keywords, ad spend, backlinks, social sentiment, and even influencer coverage. The tool aggregates data from SimilarWeb, SEMrush, Ahrefs, Google, YouTube, Reddit, and Product Hunt—saving you the cost of subscribing to each separately.

To use it, you start by exploring the market. You can filter domains by registration date, keyword rankings, traffic volume, or estimated MRR to spot rising players. Once you pick a competitor, Probedex runs a Growth Teardown: it cross-references all the data and presents it in an analyst-reviewed summary. The report scores the competitor on SEO, KOLs, ads, and social channels, and ends with a prioritized action plan. Each recommended move is tied to the exact data behind it and ranked by impact and effort. You can also save domains to a watchlist and get alerted when their traffic or keywords shift.

The tool is designed for SaaS founders who want to stop guessing and start replicating what works. It's especially useful for early-stage startups that need to find keyword opportunities without spending on expensive enterprise suites, or for growth teams that want to reverse-engineer a rival's playbook. The first full teardown costs $19.90 with no subscription required, and the platform is priced at $59 per month for ongoing access. If you've been relying on manual research or ChatGPT guesses, Probedex offers a concrete, data-backed alternative.
