Spent most of the last year building and testing Reddit automation infrastructure across three different approaches. Sharing the breakdown here because I see a lot of people starting from scratch and landing on the wrong layer.
Public Reddit API
The obvious starting point for anyone technical. Well documented, easy to work with, fast to build on. The problem is fundamental and not fixable by building better on top of it. The public API identifies itself as a developer tool, not as a user. Reddit's systems know the difference. Requests made through the public API carry a different trust classification than requests made from the iOS app. Account lifespans through API based tools are consistently shorter. Post visibility is lower. The API rate limits are also increasingly aggressive for anything that looks like bulk behaviour. Building on the public API means accepting a permanent trust ceiling that you cannot engineer your way around.
Appium iOS automation
A significant step up. Appium with XCUITest lets you automate the actual Reddit iOS app running on a real device. Reddit's servers see genuine iOS client traffic because it genuinely is. The trust scores are dramatically better than anything the public API produces.
The problems are operational. Getting Appium working reliably across multiple devices is a serious engineering project. WebDriverAgent needs to be built and signed to each device. Sessions need to be managed individually. iOS updates and jailbreak instability can take down your entire setup. At 10 devices it is manageable. At 30 plus it becomes a full time infrastructure maintenance job. The capital cost of the devices is also real.
iOS protocol replication
This is the approach I ended up building toward after hitting the ceiling on Appium at scale. Instead of automating a physical device, you capture the complete iOS client identity from a real Reddit account on a real device, every identifier, header, token, and fingerprint that Reddit's servers expect, and replicate that identity server side. Every request for that account is made using the original iOS signature. No device. No jailbreak. No Appium.
Reddit's servers see an iPhone because the request looks exactly like one. The account never loses its iOS identity between sessions. No token expiry. No re authentication. No device to maintain.
The trust scores are equivalent to phone farm accounts because from Reddit's perspective the account is still running on the same iPhone it always was. The operational overhead is a dashboard.
If you are evaluating Reddit automation infrastructure right now, the question to ask is not which tool has the best feature set. The question is which layer of the stack produces traffic that Reddit classifies as genuine iOS. Everything else is optimising around a trust score ceiling you may not even know you have.
Happy to go deeper on any of the three approaches if people have specific questions.
