An onelink.to alternative, compared on facts

First: which OneLink do you mean?

Two unrelated products go by this name, and picking the wrong page wastes an afternoon. onelink.to is an app-link tool, and it is what this page compares against. AppsFlyer OneLink is part of a mobile measurement platform and solves a different problem — if that is the one you are evaluating, start with the AppsFlyer page instead, because nothing here is a replacement for it.

The one question that decides it

Where do your links get tapped?

If the answer is mostly email, a website, a README or an ad that opens a real browser, both products do the same job and you should pick on price and on whether you need an API or seats — in which case onelink.to probably wins, and the sections below say why.

If the answer is Instagram, TikTok or messaging apps, the link is being opened inside somebody else’s in-app browser, and that is where these two products stop being interchangeable.

The comparison

onelink.to figures are their published plans as recorded on 2026-08-10. “Not documented” means their public materials do not describe the feature — it is not a claim that the product lacks it, and nothing in that column is a test result. Prices change; check theirs before deciding.

Where onelink.to is ahead

Four rows decide the question outright if any one of them describes you: a stats API, team seats up to 100, unlimited clicks on every plan, and a bigger free tier.

• A stats API. If you pull click data into your own dashboard or warehouse, they have an endpoint for it from their $40/mo plan up. AppIn does not, in any plan: ours is per-link analytics you read in the browser.
• Team seats, up to 100 on their top plan. AppIn is a single-account product. An agency running links for a roster of clients is better served by them today.
• Clicks they do not count. Traffic is unlimited on every one of their plans, free included; what their plans meter is how many links you may have. Ours meter clicks as well. If one link carries all your volume, that difference is the whole comparison.
• A bigger free tier. Both products have one; theirs holds three links, and it stops being ad-free after a thousand clicks in a month. Ours is smaller — compare it against what our plans include before assuming either will fit.

What the in-app browser row actually means

Most app links are published where they will be opened inside somebody else’s browser — an Instagram bio, a TikTok profile, a link in a message. That in-app browser is a web view running inside the host app, and it renders web pages fine. What frequently fails is the next step: handing the visitor from the web view to the App Store, which is a separate application. When that hand-off is declined, nothing is reported. No error, no fallback, a blank page, and a visitor who concludes your app does not exist.

It is worth knowing about whichever product you choose, because it is silent: the click is counted, the install never happens, and nothing in your analytics is labelled as a failure. It is also, in our experience, the single largest gap between what a social channel appears to deliver and what it delivers.

An AppIn link handles this by leaving the in-app browser before the store hand-off: the page asks the host app to reopen it in the phone’s real browser, and the store hand-off then happens where it works. It runs on load, so there is nothing for the visitor to tap and nothing for them to understand. This runs on iOS and on Android where the host app uses an in-app browser too — measured on real devices, not assumed. Where there is no in-app browser to leave — a real browser — the link simply opens the store the ordinary way.

We have not tested onelink.to’s links and will not imply a result we do not have. The test costs two minutes either way, and it is the same test for both: publish a link on a real profile and tap it from inside the app.

What the campaign-parameter rows actually mean

Apple’s App Store reads a campaign token (ct) alongside a provider token (pt); without the provider token the campaign does not appear in App Store Connect at all. Google Play reads UTM values inside a referrer parameter. Both are fiddly to assemble by hand and easy to get subtly wrong, which is why so many published links carry a campaign token that shows up in no report anywhere.

An AppIn link composes the Apple ct and the Play referrer — utm_source and utm_campaign — on every click, from the campaign name on the link and the source it can see. The provider token is the part only you have: paste your pt in once and it goes out with every click after that. Nobody can generate that value for you, and a link that made one up would be sending Apple a number matching nothing.

This is not attribution and we do not call it that. It tells one campaign from another in the reporting you already have, and it stops there. AppIn does no install attribution and no fingerprinting, and it does no deferred deep linking — the trick where a payload survives an install so a brand-new user lands on a particular screen. That one is deferred because it has to wait for the install, which is why it needs both attribution and an SDK inside your app, and an SDK is the thing this kind of tool exists to avoid. If you need it, that is a mobile measurement platform’s job, and an AppIn link can point at one.

Which one to pick

• Choose onelink.to if you need an API to pull stats from, seats for a team, or the larger free allowance.
• Choose AppIn if your links live in social bios and messaging apps where the in-app browser eats them, or if you want store campaign parameters composed correctly without adding an SDK.
