5 Jam alternatives for reviewing AI agent browser work

Suppose your coding agent says it fixed the checkout button. Before merging, you want to watch it add an item, click Checkout, and reach the payment form. You also want to see whether that run produced browser errors. Which tool helps you review that evidence?

By the Rill team Reviewed

Start with the job, then choose the tool.

Jam is already a credible option for this workflow. Its CLI supports agent-driven recording and browser diagnostics, as well as importing Playwright videos and traces. You do not need to leave Jam simply because you use a coding agent.

First compare tools for reviewing the check you already ran. If you also need to explain the change on camera, discover failures, or host the browser itself, consider the related tools below. The groups describe reasons to evaluate each tool; their capabilities can overlap.

01 / A recording your reviewer can inspect

Rill: take one browser check from your agent to your PR.

Ask your agent to record the checkout check before and after its fix. Open the two links, watch what happens after the Checkout click, and inspect the captured console logs and network requests. Attach the recordings and the agent’s assertion results to the PR so your reviewer can examine the same runs.

Here is that kind of check in a demo shop: add a backpack, review the cart, and reach checkout. The embedded Rill recording lets you follow the shopper’s journey.

Choose Rill for
A focused, shareable record of an agent-performed check, with evidence for a human reviewer or the next agent.
Know the boundary
Your agent runs the check; Rill records it. Capture follows the initially selected page. Uploaded video files do not reconstruct diagnostics or import a Playwright trace.
Cost
Free and Pro plans. Check current recording and storage allowances for your expected usage.

From “Add to cart” to checkout

The requested check: add the everyday backpack, confirm it appears once in the cart, and open checkout with the same item in the order summary.

What worked: the backpack was added, the cart showed one item, and checkout displayed the order summary. Watch the recording to see each step.

What you can review: open the recording in Rill to watch the shopper’s journey and inspect the browser activity captured alongside it.

Where this check stops: at the checkout form. No customer details were entered and no order was placed.

Record a flow in your own app, then open the link your agent returns to see what happened before you approve the change.

Rill vs. Jam: compare the workflow you will actually use.

Both tools support recording agent browser work with diagnostics. Jam also documents Playwright video-and-trace import; Rill’s existing-video upload is video-only. That distinction matters if your evidence already comes from a Playwright test run. See Jam’s CLI documentation and Rill’s CLI reference.

Record the same check in both tools. Compare the setup steps, the evidence your reviewer receives, and what the next agent can inspect. The questions in the review checklist below give you a concrete way to evaluate the two runs.

For cost, compare your actual usage against Rill’s plans and Jam’s current plans. A feature list alone does not establish which will fit your team.

Try it on one change

Record a flow in your own app.

Replace the URL, steps, and expected result in this template. For the checkout example, specify the test item, how to add it to the cart, and the payment-form element your agent should assert is visible after clicking Checkout.

Template for your own browser check

Install and read the Rill skill at https://userill.dev/skill.md
for this project, then use it to record one useful browser flow.

Follow our current task when clear; otherwise choose a short,
non-destructive smoke test. If I provide a flow, use these details:
- App URL: <app-url>
- Steps and test data: <what to do>
- Expected result: <what should happen>

Check prerequisites and browser control, and start anonymously if
I’m not connected. Ask if the target is unclear or application
changes are needed.

Return a playable recording link, when it expires, the tested commit,
what you checked, assertion results, and anything not verified.
Draft an evidence section for my PR.

Open the returned recording and inspect it before attaching it to the PR. Include the tested commit, assertions, and untested cases. The agent quickstart gives you a starting point.

02 / Explain the change

Loom: a recorded walkthrough for your team.

Loom homepage · September 25, 2026

Loom is worth considering when the explanation is as important as the browser flow. Its screen and camera recording, editing, captions, and sharing support narrated demos and bug walkthroughs. See Loom’s product overview and Loom for Jira.

Choose it for: communicating what changed and why. Tradeoff: if your goal is an agent-operated capture-and-inspect loop, evaluate that workflow separately from the quality of the video message. Check Loom’s current plans for the features you need.

03 / Ask QA to investigate

Replay: automated exploration and failure investigation.

Replay homepage, captured September 25, 2026
Replay homepage · September 25, 2026

Replay’s current offering, Replay QA, advertises app exploration, generated Playwright tests, recordings, and bug reports with proposed root causes and fixes. That asks the product to take on more of the testing and investigation process. See Replay QA’s current offering and plans.

Choose it for: exploring what might be broken and generating tests. Tradeoff: evaluate the generated checks and findings against your own requirements. If you already know the flow and your agent performs it, Rill’s role is to capture that execution for review.

04 / Stay close to the test

Playwright Trace Viewer: inspect the test you already run.

If your team already uses Playwright, start by evaluating its Trace Viewer. It lets you inspect recorded actions, page snapshots, and network activity. You can open traces locally or in the browser, including remotely hosted traces by URL. See the official Trace Viewer guide.

Choose it for: debugging existing Playwright tests. Tradeoff: your team manages trace capture and access to the artifacts. Trace Viewer is part of Playwright’s open-source tooling; account for your own test execution and artifact storage. Use Rill alongside it when a hosted video recording with Rill’s sharing and inspection workflow helps your reviewer. Rill does not replace your test framework.

05 / Run browsers in the cloud

Browserbase: infrastructure with session visibility.

Browserbase homepage · September 25, 2026

Browserbase is relevant when you need cloud browsers for your agents. It includes live viewing, session replay, console output, and network traces. Its observability tools already provide visibility into browser sessions.

Choose it for: hosting and operating browser automation. Tradeoff: this is a broader infrastructure decision than selecting a PR recording tool. Check Browserbase’s usage and plan pricing, and evaluate whether its session-review tools already cover your needs before adding another product.

Make the decision with one representative run.

Use the same checkout steps, test item, and expected payment form in both runs. Attach each recording with the tested commit and assertion results. Then ask a teammate to review them without a narrated explanation.

  • Can the reviewer find the Checkout click and see which page appeared next?
  • Does the accompanying result explicitly say whether the payment-form assertion passed, failed, or was not checked?
  • Can they inspect the console errors and network requests captured during that run?
  • Can the next agent read the shared diagnostics and identify a concrete next check?

If Jam already gives your team what it needs, keep it. Choose another tool when the comparison reveals a specific improvement in setup, review, or handoff.

Common questions

Can I start using Rill from my coding agent?

Yes. Give it the setup-and-recording prompt. It can check prerequisites and follow the CLI instructions; complete any account approval it asks you to perform.

Does Rill run my tests?

Your agent runs the checks and assertions. Rill captures the browser work. A recording shows one execution; it does not establish coverage or replace code review.

Do I need to migrate my existing Jam recordings?

You can evaluate Rill on a new run while keeping existing evidence where it is.

Can anyone with the recording link view it?

Anyone with an active Rill share link can access the shared recording and diagnostics. Check the captured data before sharing. A private PR does not make the recording link private.

Your next PR

Give your reviewer the run behind the change.

Start Rill in your coding agent, record one flow, and decide whether the evidence helps you review it.
