Highlight Run: Error Monitoring and Session Replay Platform Review: Features, Pricing, and Why Startups Use It
Introduction
Highlight (often called Highlight Run) is a modern error monitoring and session replay platform designed to help teams understand what is breaking in their web apps and why. Instead of only showing stack traces or logs, Highlight pairs backend and frontend errors with actual user sessions and network events, so you can see issues the way your users experience them.
For startups, this practical visibility is critical. When you ship fast, introduce new features weekly (or daily), and work with a lean engineering team, you cannot afford blind spots in production. Highlight aims to give founders, product teams, and engineers a unified view of errors, performance, and user behavior in one place.
What the Tool Does
The core purpose of Highlight is to help teams detect, diagnose, and resolve issues in web applications quickly. It does this by:
- Capturing frontend and backend errors as they happen in production.
- Recording user sessions (session replay) to show exactly what the user did before an issue occurred.
- Aggregating logs, traces, and performance data to provide context around each problem.
- Helping teams prioritize issues by impact, frequency, and affected users.
Instead of debugging from vague bug reports like “the page froze,” teams can jump into a replay of the session, inspect console logs, network requests, and stack traces, then fix the root cause with confidence.
Key Features
1. Session Replay
Highlight captures user sessions so teams can watch how users interact with the app and what led up to an error or drop-off.
- Pixel-perfect replays of user actions: clicks, scrolls, navigation.
- Event timeline to jump to specific points, like when an error occurred.
- Privacy controls (configurable masking) to avoid collecting sensitive user data.
2. Error Monitoring (Frontend and Backend)
Highlight tracks errors across your stack, allowing you to see where things are breaking and how often.
- Frontend error capture for JavaScript/TypeScript frameworks (React, Next.js, Vue, etc.).
- Backend error tracking via SDKs and integrations (including Node.js and common server frameworks).
- Error grouping to avoid alert fatigue and track a single root cause across many occurrences.
- Stack traces, metadata, and user info attached to each error for fast diagnosis.
3. Logging and Tracing
Beyond errors, Highlight can capture logs and traces to provide deeper context.
- Application logs linked to sessions and errors.
- Distributed traces to follow a request across services (helpful for microservice architectures).
- Search and filter capabilities for logs by severity, endpoint, user, or tags.
4. Performance Monitoring
Performance issues can be as harmful as outright bugs. Highlight surfaces performance metrics to help teams optimize user experience.
- Page load and rendering metrics for frontend performance.
- API and backend latency visibility per endpoint.
- Performance breakdown by browser, device, region, or release.
5. Integrations and Workflow
Highlight plugs into existing tools to keep your error management in the same workflow as your product and engineering work.
- Issue trackers (e.g., Jira, Linear) to create tickets directly from an error.
- Alerting tools (e.g., Slack, email) to notify teams when critical errors spike.
- CI/CD and deployment tools to tie issues to specific releases.
6. Developer-Friendly Setup
Highlight is built for engineering teams that want quick, code-level integration.
- Lightweight SDKs for popular frontend and backend stacks.
- Open-source components and transparent docs.
- Environment separation (prod, staging, dev) for safer rollout and testing.
Use Cases for Startups
1. Faster Debugging in Production
When a bug surfaces in production, startups cannot waste hours trying to reproduce it from vague reports. With Highlight, engineers can:
- Open the specific error in Highlight.
- Click through to the session replay that triggered it.
- Inspect network requests, console logs, and stack trace.
- Identify the exact user flow and conditions that caused the bug.
This shortens time-to-fix dramatically, especially for hard-to-reproduce issues like race conditions, browser-specific bugs, or intermittent network problems.
2. Improving Onboarding and Conversion Flows
Product teams can use session replay to observe where users drop off in key funnels:
- Signup and onboarding flows.
- Checkout and payment flows.
- Feature discovery and adoption flows.
Paired with error and performance data, teams can distinguish between UX confusion and actual technical issues, then iterate on both.
3. Supporting High-Touch Customer Accounts
For B2B SaaS or enterprise-focused startups, Highlight can be invaluable in customer support.
- Support teams can pull up a user’s session to see what went wrong.
- Engineers can reproduce and fix account-specific issues quickly.
- Customer success can proactively identify patterns of friction for key accounts.
4. Guardrails for Rapid Shipping
Startups often ship quickly with small QA teams. Highlight acts as a safety net:
- Monitor each release for new errors or performance regressions.
- Set alerts for error spikes after a deployment.
- Use logs and traces to ensure new features behave as expected in production.
Pricing
Highlight offers a combination of free and paid tiers, usually based on usage (number of sessions, errors, or volume of data) rather than per-seat pricing. Exact pricing may evolve, but the general structure is:
| Plan | Who It’s For | Key Inclusions |
|---|---|---|
| Free Tier | Early-stage teams, prototypes, small projects |
|
| Growth / Startup Plan | Growing startups in production with active users |
|
| Business / Enterprise | Scaling companies with complex stacks or compliance needs |
|
Pricing is typically transparent and usage-based, so teams can start free and gradually scale up as user traffic and monitoring needs grow. For the most accurate, current pricing, check the pricing page on the Highlight site.

Alternatives
Highlight sits in a crowded space of monitoring, replay, and observability tools. Here are some notable alternatives and how they compare at a high level.
| Tool | Focus | Typical Strengths vs. Highlight |
|---|---|---|
| Sentry | Error monitoring and performance | Very mature error tracking and performance monitoring; broad language support; less native focus on session replay. |
| LogRocket | Session replay and frontend monitoring | Powerful session replay and UX diagnostics; strong for frontend-heavy teams; pricing can be higher for large traffic. |
| FullStory | Product analytics and session replay | Advanced product analytics on top of replay; built for large product orgs; often more expensive and enterprise-focused. |
| Datadog | Full observability (logs, metrics, traces) | Comprehensive infrastructure and application monitoring; powerful at scale; more complex and often overkill for early-stage startups. |
| Hotjar | UX research and heatmaps | Better for qualitative UX research (heatmaps, surveys); not a full error monitoring / dev-focused tool. |
Who Should Use It
Highlight is particularly well-suited for:
- Pre-seed to Series B startups building modern web apps that ship frequently and need fast feedback loops.
- Product-led SaaS companies where understanding actual user behavior and issues directly impacts activation and retention.
- Small to mid-sized engineering teams that want a single platform covering error tracking, replay, and basic observability rather than stitching together several tools.
It is less ideal if you:
- Primarily operate heavy backend or infrastructure workloads with minimal UI (where full-stack observability like Datadog or Honeycomb may be a better first choice).
- Need deep mobile-native monitoring (iOS/Android) as your primary use case.
- Already have a heavily standardized toolchain around a legacy observability suite and cannot introduce new vendors.
Key Takeaways
- Highlight combines error monitoring, session replay, logging, and performance data into one platform aimed at modern web startups.
- It strongly benefits teams that need to quickly debug production issues, understand user flows, and support customers with high context.
- The free tier makes it accessible to early-stage teams, while usage-based paid plans scale with your traffic.
- Compared with older tools, Highlight offers a more unified, developer-friendly experience but may require careful tuning for cost and privacy as you grow.
- For many early and growth-stage startups, Highlight can serve as the primary “eyes on production,” reducing time to detect and fix issues and improving user experience.
