The Amplitude alternative with the replay behind the numbers

• The replay behind each number. Click a funnel drop to see who left, and play their sessions from the moment they left. A recent event in the explorer opens its replay when the recording is ready.
• Ranked cases, counted exactly. Sequential groups the same problem across your users' sessions and counts exactly how many people hit it. Active problems come first. Then come the problems that hit the most people, weighted by the share who gave up.
• Know which recording to open. Evidence ranks your judged sessions by how much they need a look, and "Watch" opens the replay close to where the person struggled.
• Why people left a step. The drop panel shows the cases in the sessions where people left, and how long they stayed on the step before they left.
• Before and after the fix release. Record the release and name the case that it fixes. Sequential then counts the same problem before and after that release. It states what changed.
• Your Amplitude SDK stays. Keep the Amplitude Browser SDK. Your track, setUserId, identify and autocapture calls keep working.

1. 01

   Create your account

   Create an account in the hosted preview with your work email and a password. Setup has four steps: Organisation, Project, Install and Agent.

2. 02

   Point amplitude.init at Sequential

   Keep the Amplitude Browser SDK (@amplitude/analytics-browser). In the amplitude.init call you already have, replace the API key with your Sequential Amplitude ingest key and add serverUrl. Remove a serverZone option, because serverUrl replaces it, and leave useBatch off.

3. 03

   Add the recorder line

   For web replay, add the recorder line. The recorder reads Amplitude's session id when the Amplitude SDK is on window.amplitude, so your events show under the replay, in time order.

4. 04

   See your first events

   The Install step of setup changes from "Waiting for the first event." to "It works" when the first event arrives. Events usually show within about a minute.

amplitude.init('YOUR_AMPLITUDE_INGEST_KEY', { serverUrl: 'https://YOUR_SEQUENTIAL_API_HOST/2/httpapi' });

Your coding agent can do the install. Copy one prompt into it. It adds Sequential to the analytics you already run, runs your build and tests, and lists every file it changed. You read the diff.

• Connect your coding agent. Ask in plain words over MCP, and your agent gets the problem, how many people had it and the replays. The path /mcp/readonly does not list the tools that change data, with one exception: getting a fix brief marks the case as handed off.
• A fix brief for each case. Anyone on the project can copy the fix brief into a ticket or open a GitHub new-issue page with the brief filled in.
• Release check. Record the release with one call from your deploy, and name the case that it fixes. Your agent can make the call with a token that can write releases. The case then shows the rate before and after.
• Ask. Type one plain sentence, and Sequential lists the sessions that likely show it, strongest first. When it can point to the moment, the row shows it with its time, and a click opens the replay there.
• Your Questions. Start from twelve default questions. Owners and admins can reword, switch off or add questions, up to 24, and Try it runs a draft on a real session from the last 7 days before you save.
• Backend SDK for Node. @usesequential/node sends events from your server and puts them on the same person as the browser events. An error from your server opens a case at its first occurrence.
