Astro ASO Alternatives: Free, Cheaper, and for Windows

Short answer

The best Astro alternative depends on why you are leaving. If the reason is cost, OpenASO, RespectASO, and self-hosted AsoBeast are free. If you need Windows, Astro has no Windows version, so use ASO.dev’s Windows app, a browser tool such as Applyra, ASO Atlas, or Sonar, or a Docker setup. If you are on a Mac and happy to pay, Astro’s $108 a year is already near the low end, and the paid alternatives save you little.

OpenASO publishes this comparison and competes with every product in it, so weigh it accordingly. Details come from each product’s own site, checked November 1, 2026. We have not run accuracy tests on any of them.

How do the Astro alternatives compare?

“Not stated” means the product’s site does not say either way. ASO Atlas’s page only covers Apple’s store. ASO.dev manages Google Play metadata and releases, but its pricing page says Google Play ASO analytics is not available yet.

Is Astro worth it?

Astro is worth it if you work on a Mac and would rather pay for a commercial product than run or assemble something yourself. Its site lists $9 a month, billed annually at $108, with unlimited apps and keywords, daily rank tracking, competitor keyword suggestions, ratings analysis, and more than 60 countries.

Three terms are worth reading before you buy:

• One license, one Mac. Astro’s terms cover one macOS device per license.
• Annual billing. It renews yearly, and when a paid period ends, the app goes back to the demo.
• A 14-day refund window. You can ask for a full refund within 14 days of purchase, and none after that.

Astro also fits if you rely on its translation workflow. Even RespectASO’s own comparison lists keyword translation, CSV import, tags, and temporary apps on Astro’s side, without listing them for RespectASO. That comparison comes from a competitor, so read it as one more vendor’s view. For a closer look, see OpenASO vs Astro.

Is there a free alternative to Astro?

Yes, and there are four that differ in a useful way:

• OpenASO is a free Mac app under the MIT license. It tracks keywords, rankings, competitors, ratings, and reviews, and stores the data locally. Popularity scores come from your own Apple Ads account.
• RespectASO has a free Mac app and a free Docker edition under AGPL-3.0. Its README says an Apple Ads API key is optional, and that the app otherwise relies on the public iTunes Search API. Its AI features need the paid Pro license and the Mac app.
• AsoBeast is free if you host it. Its README asks for Docker Compose, about 2 GB of memory, and 5 GB of disk. It covers both stores, and the project says it has no open core, so self-hosters get every feature.
• Applyra’s free plan needs no card, but it allows 1 app, 5 keywords, and 7 days of ranking history, and leaves out exports and AI suggestions.

Free has costs of its own. Self-hosting means you maintain a server, and a hosted free plan can change. The free ASO tools guide covers these trade-offs.

Which alternatives are cheaper than Astro?

Only a few, and the savings are small. Ascope is $89.99 a year, Applyra Unlimited is $99.99 a year, hosted AsoBeast Indie is $100 a year, and RespectASO Pro is £84 for 12 months with no auto-renewal. ASO Atlas is $9 a month, the same headline figure as Astro, though it also has a yearly option. Sonar and ASO.dev cost more, and ASO.dev’s Indie plan keeps only 30 days of keyword history.

So a cheaper paid tool is rarely a reason to switch on price alone. Pick on features, and on where the numbers come from. Astro says its popularity data comes from Apple Search Ads. Ascope says it needs no Apple Search Ads account, and shows Apple’s score or a marked estimate. Scores from different tools may not be the same thing, as our popularity explainer describes.

What can you use on Windows?

You have three routes on Windows, because neither Astro, OpenASO, nor Ascope runs there:

1. A browser tool. Applyra, ASO Atlas, Sonar, and hosted AsoBeast work without a desktop install.
2. A Windows app. ASO.dev offers a Windows installer. It has no web app, its trial lasts 3 days, and keyword tracking starts on the Indie plan.
3. Docker. RespectASO’s free edition and self-hosted AsoBeast run in Docker. RespectASO’s Pro features are not available this way.

If you only need a quick look at who ranks for a term, the keyword rank checker runs in any browser with no account.

What OpenASO does not do

OpenASO has no Windows version and no Google Play support. It does not estimate downloads or revenue, publish to App Store Connect, or generate screenshots, and it does not include an AI model. If you need any of those, it is the wrong pick.

How do you choose?

Take five keywords you care about and run them through two tools from the table. Compare how fast you reach a decision and whether you trust where the numbers come from. On a Mac, the OpenASO quickstart costs nothing to try. Then buy only if a free setup blocks a real need, and what ASO costs an indie app can help you size that.
