Run remote browser automation by assigning each task to a named browser session and one active controller. Prepare an authorized endpoint, compatible client and task record first. The expected output is a traceable observation tied to the correct workspace, not just a successful connection.
Distributed AI workers need a handoff rule before they need more capacity. A replacement worker must know whether work is waiting, running or uncertain. Start with the proposed read-only catalogue-status check below. No live account test, stock result or throughput measurement is supplied.
Key Takeaways
- Keep the worker, browser session and account references separate.
- Assign one controller before allowing browser actions.
- Distinguish waiting for capacity from completing a task.
- Treat a lost response as uncertain, not automatically failed.
- Verify reassignment before a replacement worker continues.
Prepare remote browser automation inputs
Start with a system you may inspect. Name the catalogue page and products the worker may read. Decide which visible stock label it should record. Keep orders, price changes and public posting outside this task. Review account lane assignments before connecting workers to logged-in workspaces.
Choose the connection method next. Playwright's BrowserType reference describes connecting to a browser started through Node.js launchServer. The client and server must have matching major/minor versions. CDP works with Chromium and has lower fidelity than the Playwright protocol. Record the method and versions in use; remote endpoints aren't all alike.
For the proposed task record, prepare these fields:
task_ref: the observation request, independent of a worker.workspace_ref: the assigned account environment.session_ref: the browser allocated for that attempt.controller_ref: the worker currently allowed to control it.product_refs: the exact catalogue records to inspect.result_ref: the observation and review location.
These are suggested coordination fields, not a Moimobi API schema. Keep endpoint credentials out of the shared result. If the environment needs dedicated routing, assess the workspace network path separately from browser availability.
Step-by-step remote browser automation: one controller per session
A queue entry isn't a browser ready to use. Selenium Grid's component documentation separates new-session requests, free Node slots and existing session routing. Its Session Map links a session to its Node. That example doesn't choose who owns your AI task. Name the controller in your own task design.
Follow this proposed sequence in a controlled environment:
- Accept the request. Record the product references and permitted page. Reject missing scope rather than letting a worker invent it.
- Allocate the session. Record its workspace and controller. Leave the task waiting when no matching capacity is available.
- Confirm identity. Read the displayed workspace and catalogue reference. A mismatch stops the attempt before collecting results.
- Collect the observation. Retain the visible label, product reference and observation time. Label a missing field as unresolved, not unavailable stock.
- Review and release. Store the result against the task reference. Confirm that the controller has stopped before making the session available again.
Review the finding from the assigned workspace before calling the task complete. A working connection isn't that finding. Keep a record of who received the session and who released it. Another operator should be able to read that history without asking the previous worker what happened.
Check remote browser automation results and handoffs
Try the proposed design with a test catalogue before using live business records. Set its labels yourself, then compare the worker's findings with the page. Keep the test results apart from real stock records. No sample labels or counts here are claimed as actual stock data.
- Correct assignment: the task and displayed workspace agree. Otherwise quarantine the observation for review.
- Known record: each finding identifies a requested product. Extra records don't count toward completion.
- Missing field: an absent label stays unresolved. Don't let an AI inference become a stock status.
- Controlled handoff: the old controller is stopped or fenced out before reassignment. Record the new controller and attempt separately.
- Reviewable output: the result retains its observation time and source reference. A later page change requires a new observation.
Ask the implementer to show how an old controller loses access. A field named owner isn't proof that only one worker can act. Consult the execution reference library when reviewing related design choices. One working connection doesn't prove the handoff works.
Compare these failure cases in the same fixture. They need different review decisions, even when the worker reports a timeout.
| Controlled failure | Expected finding | Next decision |
|---|---|---|
| Worker stops before reading the label | No completed observation | Resolve control, then schedule a new reading |
| Result saved before the worker loses contact | Saved result may already exist | Inspect that record before repeating work |
| Workspace changes during recovery | Old finding belongs to the old assignment | Stop and ask the owner to confirm scope |
These are proposed tests, not completed runs. Retain the observed outcome next to the expected one. A result from the wrong workspace fails the review even if its label happens to match.
Recover uncertain work and respect applicability limits
A lost connection doesn't mean no work happened. Temporal's Activity documentation describes work finishing before a Worker reports back, then being retried. It recommends idempotent Activities and keys enforced by the called service. This is a related design lesson, not proof that repeating any browser click has no extra effect.
For the proposed read-only task, inspect the saved result and old controller first. If either status is unknown, hold the task. Resolve who can act before giving it to another worker. Keep a fresh reading as a new attempt with its own time. A normal second response isn't a reason to erase the first record.
Stop when the account is logged out, the requested catalogue isn't available or the workspace reference changes. Send the task back to its owner for corrected access or scope. An expired queue request needs a fresh scheduling decision; it isn't evidence that the catalogue was checked.
This method isn't a substitute for mobile execution. An app-only task may require a separately assessed cloud phone environment. Payments, public replies and account changes need their own authorization and outcome checks. Don't extend the read-only procedure to those actions simply by replacing its page URL.
Frequently Asked Questions
What makes browser automation remote?
The controller connects to a browser running elsewhere. Worker distribution is a separate scheduling decision.
Can multiple workers share a session?
Prefer one active controller for the proposed task. Demonstrate how handoffs prevent overlap before sharing access.
Is CDP the same as a Playwright connection?
No. The cited BrowserType reference describes different attachment methods and their compatibility limits.
Does a task queue preserve the logged-in account?
A queued task doesn't prove account continuity. Check the assigned workspace when its session becomes available.
Should a connection timeout trigger another attempt?
Inspect existing work and controller status first. An uncertain outcome needs review before reassignment.
Does remote execution reduce costs?
No saving is established here. Compare actual browser capacity, queue delays and operator recovery work using your own records.
How should Moimobi capabilities be evaluated?
Request a demonstration of workspace assignment, handoff and result retention. Treat undocumented behavior as unknown, not accepted functionality.
Add workers only after the handoff works
Complete one allowed reading and one interrupted handoff in your test catalogue. Check the workspace, controller release and source of the result. Add workers only when a new operator can explain the last attempt without guessing. Remote access gives you a browser connection. A shared task also needs a clear owner and records that survive a handoff.
