Bug reproduction made easy for Engineering & QA

Reduce MTTR and eliminate ‘cannot reproduce’ tickets

FullSession gives Engineering & QA the evidence they need to debug faster, prioritize the right issues, and protect critical flows.

Faster bug reproduction

See what users did before an error, which device and browser they used, and which API calls failed — so you can reproduce issues without guesswork.

Lower MTTR on production issues

Go from vague bug reports to clear, replay-backed incidents that show you root cause in minutes instead of hours.

Focus on high-impact bugs

Understand which errors break signup, checkout, or onboarding and work with Product to fix what actually affects users and revenue.

First 7 days Activation Playbook

Day 1: Identify your top 3 production issues affecting critical flows (signup/checkout/onboarding).

Day 2: Set up alerts for key errors/frustration signals; baseline frequency and impacted pages/steps.

Day 3: For each issue, pull 3–5 representative sessions and document reproduction steps + environment context.

Day 4: Fix the highest-impact issue first (most users blocked / most severe flow break).

Day 5: Verify in new sessions that the failure mode is gone; watch for regressions on adjacent steps.

Day 6: Add a guardrail (alert, test, or logging) to prevent regression; verify error/failure signals trend down.

Day 7: Review issue trends; update the “top blockers” list and create a weekly triage rhythm.

Built for Engineering, QA, and everyone on the hook for incidents

Give each technical role the context they need to debug quickly — and a shared view of what really happened in production.

Engineering leaders

Cut MTTR, reduce firefighting, and give your team clear evidence for prioritizing bug fixes alongside roadmap work.

Senior engineers

Jump straight from a ticket or error into the session behind it and see console logs, network calls, and DOM changes on a single timeline.

QA engineers

Record and share exact reproduction paths from pre-production and production, reducing back-and-forth with devs.

SRE & platform

Correlate frontend behavior with incidents, errors, and degraded experiences, so you see how outages impact users in real time.

Debug faster with replay + technical context

Watch exactly what happened in production and see the logs, network calls, and environment details tied to the user’s experience.

Capture sessions with technical context by default

A lightweight script records user interactions, DOM changes, console logs, and network calls, so you get a complete picture of what happened when something broke.

Click any error or ticket to watch the session

Jump from an error, ticket, or funnel drop-off straight into the replay that shows what the user did, what they saw, and which technical events fired.

Diagnose and fix issues with confidence

Use the combined view of UX behavior, console logs, API responses, and environment details to understand root cause quickly and ship the right fix.

See errors the way users experienced them

Move beyond stacks and counts. With FullSession, every error is tied to real behavior, so you can see how it affected the user journey.

Frontend and JS errors

See when and where JavaScript errors fire in the session timeline, with stack traces and affected components visible alongside user actions.

Network failures and timeouts

Correlate failed requests, slow APIs, and timeouts with the exact screens and steps users were on when things went wrong.

Performance slowdowns

Spot pages and flows where long loads or janky interactions cause users to abandon or hammer controls in frustration.

Rage clicks and dead clicks

Identify UI elements that draw clicks but don’t respond, indicating broken interactions or confusing design that leads to error-prone behavior.

Find the errors that quietly break signup, checkout, and onboarding

See where technical issues intersect with your most important funnels so you can fix bugs that directly affect revenue and key journeys.

Signup and login flows

Watch sessions where signup fails due to validation errors, slow verification, or broken form logic, and see which issues recur most often.

Checkout and payment

Spot errors, timeouts, and broken fields in checkout and payment forms, then work with product and growth to prioritize fixes.

Onboarding and activation forms

Identify technical blockers in onboarding steps and activation forms that prevent users from reaching their first value moment.

Applications & claims forms

Monitor application and claims forms for errors that could affect approvals, coverage, or enrollment, and address them before they become incidents.

Reduce MTTR with complete technical context in one place

Every minute spent trying to reproduce a bug is a minute not spent fixing it. FullSession brings user behavior, console logs, network calls, and environment details into a single view so engineers can move straight from symptom to cause.
Instead of sifting through scattered tools and partial reports, your team clicks once to see the full story—what broke, who it affected, and what to fix next.

Use shared replays and context to turn vague bug reports into clear, prioritized work that everyone understands.

Include direct links to relevant sessions in your bug tracker so any engineer can see exactly what happened without hunting for logs.

Combine error data with funnel and form analytics to focus on issues that block key journeys, not just those that generate the most noise.

Share recordings that show how bugs affect users and experiments, making it easier to align on priorities and trade-offs.

Use session replays and technical context in your incident reviews so you can learn from real behavior, not incomplete reconstructions.

“We used to spend days chasing ‘cannot reproduce’ bugs. With FullSession, we click the ticket, watch the session, and see the console and network details we need. Debugging stopped being a guessing game.”

What is bug reproduction and why is it hard?

Bug reproduction is the process of recreating a user-reported issue so you can see it fail and understand why. In modern, stateful apps, it’s difficult because users move quickly, environments vary, and logs only show a fraction of what actually happened.


FullSession lets you watch the user’s session as it unfolded — what they clicked, what loaded slowly, which errors fired—so Engineering & QA can reproduce and fix issues with far less guesswork.

Engineering FAQ

Answers to common questions about using FullSession to debug issues and reduce MTTR.

What is bug reproduction and why is it so hard for Engineering & QA teams?

Bug reproduction means recreating the exact conditions under which an issue occurred so you can see it fail and understand why. It’s hard because users, devices, and environments vary, and logs rarely capture every interaction or visual state. FullSession bridges that gap by letting you watch what the user did and see the technical events that fired as it happened.

How does session replay help engineers reproduce bugs faster?

Session replay shows the sequence of actions, states, and technical events that led up to a bug. Instead of piecing together reports and logs, engineers can watch the session, see which element failed or which request errored, and quickly spot the root cause.

How can we use FullSession to reduce MTTR on production issues?

By tying errors and tickets to specific sessions, FullSession lets your team skip the guessing and jump straight into the context of each issue. That shortens the time it takes to understand what went wrong and what to fix, which in turn reduces MTTR across recurring bug types.

Does FullSession replace our existing bug tracker or error monitoring tools?

FullSession is designed to complement those tools, not replace them. You can keep using your bug tracker and error monitoring, while using FullSession for the behavior and technical context that makes those errors easier to understand and resolve.

Will using FullSession impact application performance in production?

FullSession is built to minimize overhead by capturing events and state changes rather than heavy full-screen video. As with any script, you should test in your environment, but the goal is to provide detailed debugging insight while keeping your app responsive for users.
