Cheap rank tracker for tiny app developers

What to build

A self-hostable, open-source ASO rank-tracking tool for solo app developers and tiny studios, with a cheap hosted tier (priced per keyword-country pair, not per seat) that handles proxy infrastructure for accurate Google Play country-level rank data.

Enterprise ASO tools like AppFollow, Sensor Tower, and Appfigures price for agencies and mid-size teams, leaving solo app developers and two-person studios priced out; a free self-host option plus a near-cost hosted tier built around usage-based (keyword-country) pricing fills that gap.

Demand

Solo developers running a handful of small apps want rank tracking without paying agency-tier flat fees, and the submitter's own public pricing question on r/microsaas shows this exact positioning is resonating with that audience right now.

• r/microsaas (Reddit)Anecdote

  Tool creator posted 'My ASO tool is free to self-host and $10/mo hosted. Is that too cheap?', describing themselves as a solo builder of small apps, framing the question around whether this pricing is sustainable.

• Signal submitter (tool creator)Anecdote

  Tool creator states their ASO tool is free to self-host and $10/mo hosted, and is questioning publicly whether this pricing is too cheap relative to market norms.

• Opportunity framing (signal metadata)Analysis

  Framing positions AppFollow, Sensor Tower, and Appfigures as enterprise/agency-focused incumbents with seat-based pricing that excludes solo developers and small studios, creating room for a usage-cost-based alternative priced by keyword-country pairs.

Stack

• Node.js or Python backend
• PostgreSQL for rank history storage
• Residential/datacenter proxy provider (e.g. Bright Data, Smartproxy) per country
• Google Play & App Store scraping/search APIs
• Docker for self-host distribution
• Stripe for usage-based hosted billing

Solo + AI difficulty

The scraping and dashboard logic is straightforward for one builder with AI assistance; the hard part is sourcing and managing reliable per-country proxies cheaply enough to keep the hosted tier profitable at $10/mo, plus packaging a clean Docker self-host experience. Rough time-to-MVP (single country, basic keyword tracking, self-host + hosted toggle): 3-5 weeks.

Entry threshold

Needs a scraper and proxy network (one IP per target country to get accurate Play Store ranks) plus a Postgres/Redis backend; one person can build and ship an MVP in a few weeks, with ongoing proxy/IP cost as the main operating expense rather than compute.

Counter-signals & risks

• At $10/mo, the hosted tier may not cover the real infrastructure cost of maintaining per-country residential/datacenter proxies at scale, risking an unsustainable business model as usage grows.

• Low price could signal weak perceived value or difficulty capturing willingness-to-pay from developers who might pay more, leaving money on the table rather than reflecting a deliberate wedge strategy.

• Incumbents (AppFollow, Sensor Tower, Appfigures) could introduce low-cost indie tiers or acquire similar open-source projects, eroding the differentiation of a cheap self-hosted alternative.

• Self-hosting option may cannibalize hosted-tier revenue if proxy setup is not sufficiently difficult for technical solo developers to do themselves.
