How Momentic and MobileBoost compare across the dimensions teams evaluate most. | Category | Momentic | MobileBoost | | --- | --- | --- | | Founded | Y Combinator W24 | Y Combinator, mobile only | | Platforms | Web, iOS and Android in one suite | iOS and Android; no web | | Authoring | Cursor, Claude Code or Codex write the YAML into your repo over MCP; the CLI runs it | Agent skills and a REST API, plus a no-code visual editor | | Who edits a test | Engineers and coding agents, in the repo | Product managers and QA analysts, in QA Studio, with a step recorder | | Where tests live | YAML files in your repo, reviewed in the pull request | Their platform. Each test is a record you change through their REST API | | Device features | Hosted simulators and emulators, hundreds in parallel | Real and virtual devices, offline mode on iOS simulators, App Clips, camera injection, audio capture | | Scale | Thousands of parallel browsers, hundreds of parallel simulators and emulators | Over 100 parallel device setups, mobile only | | Track record | Notion, Retool, Webflow, Xero and Quora run on Momentic | Duolingo reports 70 percent fewer manual regression tests | | Best fit | One suite for web and mobile, written by your coding agents | Mobile-only teams who need a specific simulator feature | ## What MobileBoost does MobileBoost, which also sells as GPT Driver, tests iOS and Android apps. It reads a pull request, generates or extracts the test cases, runs them on simulators or real devices, and posts pass or fail to CI status checks. It supports offline mode on iOS simulators, App Clips without TestFlight, camera and audio injection, network mocking, and over 100 parallel device setups. Duolingo reports 70% fewer manual regression tests. MobileBoost ships coding-agent skills, a REST API, and a visual editor. It does not test the web. ## Where Momentic differs. 01 ### One suite, web and mobile MobileBoost stops at iOS and Android. If your product also runs in a browser, you buy a second tool and keep two suites. Momentic runs web, iOS and Android from the same YAML and the same CLI. 02 ### The test is a file you own MobileBoost keeps each test in its own platform, and you change it through their REST API; its generator commits automation code to its own repository. Momentic stores each test as YAML in your repo, so a change appears as a diff in the pull request, and your coding agent edits the file directly. 03 ### Written by engineers and coding agents MobileBoost's visual editor serves product managers and QA analysts; engineers use an SDK around XCUI, Espresso, or Appium. Momentic replaces that native suite with plain-English YAML written by engineers and coding agents. 04 ### The run recovers instead of failing Momentic re-resolves moved targets, retries transient failures, and writes repairs to YAML. Cached steps need no model call, and over 99% finish under 500ms, so large mobile suites stay repeatable. 05 ### Proven at enterprise scale Notion, Retool, Webflow, Xero, and Quora gate releases on Momentic across thousands of browsers and hundreds of simulators and emulators. Quora cut a 7-hour QA pass to 30 minutes, so the suite runs on every merge instead of once a release. 06 ### The mobile login is in the test Momentic provisions an inbox and a phone number that a JavaScript step can read inside a mobile test, so a one-time code, a magic link or a 2FA prompt does not stop the run. The same step can call your API to put the account in the state the test needs. 07 ### The step sees more than a screenshot Momentic resolves each step against a screenshot, the accessibility tree, and the DOM on web or the screen XML on mobile, and infers which signal matters. An element the screenshot hides, or two that look alike, still resolves. AI assertions read the same three sources. 08 ### The agents learn your product Momentic keeps a Knowledge base of your terminology, your rules for agents, and your known flows, and Memory keeps the decisions from past runs. Every AI step retrieves the relevant entries, so a new session starts with product context. 09 ### Mo finds the bugs no test covers yet Mo takes a target and a brief, plans the cases, and runs each one in its own hosted browser, simulator, or emulator. A reproducer agent retries a suspected bug from a clean session, so only a reproduced bug reaches the report. One session ran 116 agents and returned 27 bugs. You point Mo at the iOS or Android build your tests install. ## Ten ways to test a mobile app. MobileBoost is one of several ways to test a mobile app. Where the test lives decides who can change it, and how it reaches the merge gate. | Tool | Authoring | Runs on | Best fit | | --- | --- | --- | --- | | Momentic | Plain-English steps as YAML in your repo, written by your coding agent over MCP and run by the CLI | Cloud browsers, iOS simulators and Android emulators. Hundreds of simulators and emulators, thousands of browsers in parallel | Authoring and execution from one place, gated in CI | | MobileBoost (GPT Driver) | Their platform holds each test as a record. You change it through their REST API, or record it in their no-code editor | iOS and Android; simulators and real devices, 100+ in parallel | Mobile-only teams who need simulator features nobody else exposes | | Autosana | Natural-language flows in their dashboard. You can opt a repo in to files, and the sync copies them on the default branch only | iOS, Android, mobile web and desktop web; local and cloud runs | Small teams who want the agent to close the loop | | Maestro | YAML flows | Simulators, emulators and devices; local or Maestro Cloud | Mobile teams who want readable flows and a fast local loop | | Appium | Code, on WebDriver | Runs wherever you host it, including the clouds above | The suite most device clouds are bought to execute | | BrowserStack | None. Bring your own tests | Real browsers, real iOS and Android devices, manual live sessions | Coverage on a specific real device or an old browser | | Sofy | No-code editor, recorded on real devices | iOS and Android on a real-device cloud | QA teams who record on hardware | | Waldo (now part of Tricentis) | Recorded sessions, no-code steps | iOS and Android | Recorder teams inside a Tricentis estate | | mabl | Low-code recorder aimed at non-technical authors | Vendor cloud | One vendor for authoring and running, on a credit model | | testRigor | Plain-English scripts in a vendor web app | Web and mobile; vendor cloud | Teams who accept tests living outside version control | ## Who should choose which. Choose Momentic Choose Momentic if one team owns web and mobile quality and the YAML suite belongs in your repo. Notion, Retool, Webflow, Xero, and Quora gate releases across thousands of browsers and hundreds of simulators and emulators.

Is MobileBoost the same product as GPT Driver? Yes. MobileBoost sells the same mobile test agent under the GPT Driver name, and mobileboost.io carries both. Does MobileBoost test web apps? No. MobileBoost covers iOS and Android. Momentic covers web, iOS and Android from one suite. Can my coding agent write MobileBoost tests? Yes. MobileBoost ships agent skills and a REST API. The difference is the storage: MobileBoost keeps the test in the platform, and Momentic writes a YAML file into your repo over MCP. Which one runs in CI? Both. MobileBoost posts status checks from its own workflow. Momentic runs in your pipeline, returns a non-zero exit code, writes JUnit XML, and the Momentic GitHub App posts a status comment on the pull request. Does Momentic support real devices? No. Real devices are not supported. Momentic runs hosted simulators and emulators, or the local AVDs and simulators on your machine. MobileBoost offers physical devices.
