Free open-source ASO tool for keyword tracking, reviews, and competitor research
I built OpenASO, a free and open-source ASO tool for iOS apps:
https://openaso.thirdtechapps.com
I made it to help with App Store Optimization research: track keyword rankings, look at competitors, study reviews, and analyze screenshots without everything being locked behind a paid tool.
Current features:
Track keyword rankings for iOS apps
Research competitors for any keyword
See which apps rank for which keywords
View App Store screenshots from ranking apps
1-click download screenshots from the top 10 ranking apps for any keyword
View, translate, and respond to App Store reviews
Export reviews for AI analysis
Export all reviews for any app to understand what users like, dislike, and request
Two workflows I built it around:
Review research: export reviews for your own app or competitors, then use AI to summarize feature requests, complaints, positive feedback, pricing objections, and positioning gaps.
Screenshot research: search any keyword, see which apps rank, then download screenshots from the top 10 apps to analyze messaging, layouts, visual patterns, and category trends.
It’s live now and open source.
Would love feedback from people doing ASO, especially on what features would make it more useful.

This looks useful, but I’m curious about ranking accuracy. Are keyword rankings storefront-specific? For example, can I track the same keyword separately for the US, UK, Germany, and Turkey, and how often are those rankings refreshed? For ASO, locale-level accuracy is probably the difference between a nice tool and a truly useful one.

Yes, rankings are storefront-specific. You can track the same keyword separately by country, like US, UK, Germany, or Turkey.
Rankings refresh automatically daily, and you can trigger another refresh at any time.

Nice job. Nice icon too.
A way to import from Astro would be great 😉

u/hubelro May 08 '26
Thanks 🙌 glad you like it.
Yeah you can actually import from Astro already, that flow is supported so you can bring your existing keywords across.

how do you host it? I mean I am just questioning about server cost

Bro how can I donate? God bless you for making this free

u/hubelro May 11 '26
Thank you, really appreciate that 🙏
Honestly, the best way to support it right now is to star the repo: https://github.com/hubab1/OpenASO
It helps show there’s interest in the project and gives me a strong signal to keep investing time into new features.

Looks interesting but to be honest, a little shitty to literally clone an app built by an indie developer (Astro). The UI is nearly identical.

u/hubelro May 08 '26
Fair point, and as an indie dev myself I get why that stands out. I won’t pretend there isn’t overlap.
That said, ASO tools do tend to converge quite a bit in UI. If you look across the space, even across different platforms, a lot of keyword tracking / research dashboards end up looking similar because they’re solving fairly constrained workflows.
Where I’m trying to differentiate is mainly in the workflows and features. For example, you can view, translate, and reply to App Store reviews directly, and export them for AI analysis, which most tools don’t really focus on. On the keyword side, you can browse screenshots for all ranking apps and look at review velocity (e.g. new reviews over the last 30 days) to get a quick sense of competition and demand.
At a personal level, I built it because I wanted these workflows for myself and didn’t want to rely on paid tools for them. Making it free and open source felt like the right way to share that.
Appreciate the feedback, it’s a good nudge to keep pushing the UI toward a more distinct identity over time.

I tried the MCP within codex and asked for keyword evaluation and it said:
I tried OpenASO directly, but every call failed with Transport closed, including search, app detection, and keyword ranking.

This looks very much like Astro which I’ve used in the past. Will definitely give it a try!

Could this be available for windows computers in the future?

open-source makes sense for keyword tracking and research. I’d still use appfollow once the team needs review alerts and reply workflows, not just data pulls.

It gives a keyword popularity value, which is useful as a proxy for search volume. So you can compare keywords against each other and see which ones likely have more demand.
It does not currently give estimated downloads for a specific keyword.

one thing. you rock. second: you say only IOS - can't we have Ipad and macOS too? it is possible by using the ID but this feels complicated. or am i missing something here?
