GeeLark alternative for app testing and AI agents

GeeLark is a cloud phone product aimed at social media teams. It is one of the better-known names in the category, so it is often the first service people try when they need Android in the cloud. Some of them then realize their job is different: they need to test an app before release, connect phones to a CI pipeline, or give an AI agent a device to work on. For that work, the useful question is not which cloud phone is best known, but which one was built for what you do.

This article does not review GeeLark's features or pricing. Their own website is the place for that, and both change over time. It explains how cloud phone services differ by audience, what to compare when you look for an alternative, and where Clousd fits.

Cloud phones are built for different jobs

All cloud phones run Android on servers and show you its screen. Beyond that, products diverge based on who they are built for.

• Tools for marketing and social media teams organize the work around content, team roles and day-to-day handling of apps by people.
• Tools for developers and testers organize the work around builds, Android versions and automation: ADB, an API, logs, and resetting devices between runs.
• Platforms for AI agents organize the work around a screen that software can read and act on, through an API or MCP, with a person able to watch.

Clousd sits in the second and third groups: app testing, developers and AI agents, with the API as the main way in. If that is your work, the alternatives worth comparing are other services in those groups, and the criteria below matter more than any feature list.

What to compare

Device fidelity

Ask what each phone is built from. A generic Android image is fine for running one app. Testing needs real phone models with their manufacturer builds and screens, across a range of Android versions. Our phones are built from 150+ real models from Samsung, Pixel, Motorola, OnePlus, Xiaomi and others, and run Android 12 to 17.

Access for code, not only for people

For testing and agents, a polished desktop app is secondary. What matters is how software reaches the phone:

• A REST API to create, start, stop and reset phones from scripts and CI.
• ADB to install builds, open a shell and read logcat from your own terminal.
• MCP so an AI assistant can see the screen and act on it.
• An SDK in the language your team uses.

We offer all four: a REST API, an MCP server, a Python SDK and ADB over a relay, plus a live screen in the browser for people.

Resets and repeatability

A test is only useful if the next run starts from the same place. Ask how a phone returns to a clean state, how long that takes, and whether your CI can trigger it without a person clicking through a dashboard. Our phones can be reset to a fresh state, and a new phone is created in about a minute, so each run of a pipeline can begin on a clean device instead of inheriting whatever the previous run left behind.

Tasks in plain words

Some work is easier to describe than to script. With Tasks, you give a phone a goal in plain words, such as "install the build, open settings and report the version shown", and the agent does it while you watch. Your own agent can also drive the phone step by step. The page on phones for AI agents explains both modes.

Country, time zone and language

Testing localized apps and store pages means the phone should connect from the market you care about. Our phones connect from the country you choose, such as the US, the UK, Germany, Brazil or Indonesia, out of 45 in total, with the matching time zone and language.

Data location

Know where your phones and the data on them live. Our servers are in the EU, in Frankfurt and Helsinki.

Pricing model

Compare pricing models, not only numbers: per minute, per month, caps and trials. We charge $0.004 a minute while a phone runs, never more than $0.80 a phone a day, or plans from $20 a month, and the first 30 minutes are free with no card. The guide to finding the cheapest cloud phone shows how to work out the monthly cost for your own usage.

Cloud phone alternatives at a glance

If you are looking at alternatives in general, cloud phones built for one audience are only part of the picture. These are the four options teams usually weigh:

Who should stay, who should switch

Stay with a social-media-oriented service if your team's work is content and the tool fits that workflow. Switching for its own sake costs time and gains nothing.

Some companies end up using both kinds: one tool for the marketing team's daily work, another for the app their engineers ship and the agents they build. That split is reasonable, as long as each team uses the tool designed for its job and nobody has to bend a content tool into a test lab or the other way round.

Consider a cloud phone built for testing and agents if:

• You ship an Android app and need to check it on several models and Android versions before each release. The app testing workflow shows how that fits together.
• Your phones should be created, reset and stopped by your CI rather than by hand.
• You are building or running AI agents that need a real Android screen.
• You need to know exactly where your devices run.
• You want per-minute billing for work that comes in bursts.

How to evaluate an alternative in an hour

1. Write down three real tasks: one manual check, one scripted run and one agent task.
2. Start a trial on each candidate.
3. Time how long it takes to get the first phone running and your app installed.
4. Run the scripted task through the API or ADB, and the agent task through MCP or the service's own agent.
5. Compare the meter or bill afterwards with your estimate.

A service that handles all three tasks inside an hour will handle most of your real work. For a broader list of questions, see how to choose a cloud phone.
