## Comparisons (full content)

### Nevision vs Sentry

URL: https://nevision.app/alternatives/sentry
Category: Error tracking

Sentry is the dominant error tracking platform — used by hundreds of thousands of teams. It does errors well. But session replay is a $50/mo add-on, uptime monitoring isn't first-class, and server metrics aren't its category. If you're paying for Sentry plus a separate session replay tool plus a separate uptime tool, Nevision is a single subscription that replaces all three.

**Comparison**

| Feature | Nevision | Sentry |
| --- | --- | --- |
| Free errors/month | 3,000 | 5,000 |
| Paid plan starts at | $39/mo | $26/mo |
| Session replay included | Yes | Add-on (+$50/mo) |
| Uptime monitoring included | Yes | No |
| Server CPU/memory metrics | Yes | No |
| Frontend log management | Yes | No |
| Backend log management | Yes | Logs add-on |
| Source maps | Yes | Yes |
| Self-host option | No | Yes |
| Open source | Recorder only | Yes |

**When to choose Nevision**

- You want errors + replay + uptime + RUM + logs + server metrics in one bill.
- You're a small or mid-sized team and Sentry's add-on pricing is creeping past $200/mo.
- You value simple flat-rate pricing over per-event metering.

**When to choose Sentry**

- You need to self-host. Sentry has a robust on-prem story; Nevision is SaaS-only.
- You depend on Sentry's mature integrations ecosystem (Jira, GitHub Actions, GitLab, etc.) — Nevision is newer and has fewer.
- You're an enterprise with very high error volumes and existing Sentry contracts — switching cost may not be worth it.

**FAQs**

- **Can I migrate my Sentry setup to Nevision?**
  Yes. Replace your Sentry SDK init with the Nevision recorder script — error capture, source maps, breadcrumbs, and release tagging are conceptually equivalent. We have a migration guide in the docs. Historical Sentry data does not transfer (different storage formats), but new errors flow into Nevision immediately.
- **Is Nevision's error tracking as deep as Sentry's?**
  For frontend JavaScript: yes — same fingerprinting model, source maps, releases, environments. For backend exceptions across 30+ languages with deep auto-instrumentation: Sentry is broader. Nevision currently emphasizes JavaScript-first with backend support via the logs API.
- **What about Sentry's performance monitoring (APM)?**
  Sentry's APM (transactions, distributed traces, slow queries) is more comprehensive than Nevision's RUM. Nevision focuses on frontend RUM (Core Web Vitals) and infrastructure metrics rather than distributed APM today.

### Nevision vs LogRocket

URL: https://nevision.app/alternatives/logrocket
Category: Session replay

LogRocket pioneered modern session replay for product teams. It's a polished product. But it starts at $69/month for 1,000 sessions, and adding error tracking or uptime monitoring means another tool. Nevision delivers the same DOM-based replay quality at a lower entry point and bundles errors, uptime, performance, and server monitoring in the same plan.

**Comparison**

| Feature | Nevision | LogRocket |
| --- | --- | --- |
| Free sessions/month | 500 | 1,000 |
| Paid plan starts at | $39/mo (5K sessions) | $69/mo (1K sessions) |
| DOM-based replay | Yes | Yes |
| Privacy-first masking | Yes | Yes |
| Includes error tracking | Yes | Yes |
| Includes uptime monitoring | Yes | No |
| Includes Core Web Vitals | Yes | Yes |
| Includes server metrics | Yes | No |
| Frontend + backend log unification | Yes | No |
| Identify users + custom traits | Yes | Yes |

**When to choose Nevision**

- You want 5x more sessions per dollar (5,000 sessions for $39 vs LogRocket's 1,000 for $69).
- You also need uptime monitoring and server metrics — LogRocket doesn't ship these.
- You want flat-rate pricing without enterprise sales cycles.

**When to choose LogRocket**

- You need LogRocket's specific integrations (Jira, Asana, Linear, Intercom, Zendesk, HubSpot) — Nevision has fewer today.
- You want their AI-powered session insights — LogRocket has more mature ML on top of replays.
- You're already standardized on LogRocket and the bundled features in Nevision aren't pain points.

**FAQs**

- **Is the replay quality really comparable?**
  Yes — both products record the DOM (not video), reconstruct via rrweb-style replay, and run at 60fps. Nevision uses rrweb under the hood. The replay UX (timeline, console, network panel) is similar.
- **Can I export my LogRocket sessions?**
  LogRocket allows session URL sharing but no bulk export. So historical sessions stay there. New sessions captured by Nevision after install will accumulate from day one.
- **Does Nevision support React DevTools-style component inspection in replays?**
  Not yet — that's on the roadmap. LogRocket has it today.

### Nevision vs Hotjar

URL: https://nevision.app/alternatives/hotjar
Category: Session replay + heatmaps

Hotjar is built for marketers — heatmaps, surveys, funnels. The replay feature is secondary and capped at 35 sessions per day on the free plan. If you're a product or engineering team that wants replay primarily for debugging (linked to errors, with full stack traces), Hotjar isn't the right tool. Nevision is.

**Comparison**

| Feature | Nevision | Hotjar |
| --- | --- | --- |
| Free sessions/day | ~16 (500/mo) | 35 |
| Paid plan starts at | $39/mo (5K sessions/mo) | $32/mo (100 sessions/day) |
| DOM-based replay | Yes | Yes |
| Includes error tracking | Yes | No |
| Includes uptime monitoring | Yes | No |
| Heatmaps | No | Yes |
| Funnels | No | Yes |
| Surveys | No | Yes |
| Backend log management | Yes | No |
| Server CPU/memory metrics | Yes | No |
| Built for engineering debugging | Yes | No |

**When to choose Nevision**

- You want session replay primarily to debug errors and crashes, not to optimize landing page conversion.
- You also need error tracking, uptime, RUM, logs, server metrics — Nevision is one tool.
- Your audience is engineers and PMs, not marketers.

**When to choose Hotjar**

- You need heatmaps, funnels, on-site surveys, or product feedback widgets — Hotjar is the right category for those.
- Your primary buyers are marketing or growth teams optimizing conversion.
- You're not deeply technical and Hotjar's UX feels right for your team.

**FAQs**

- **Will Nevision replace my heatmaps?**
  No — Nevision doesn't generate aggregate heatmaps today. If heatmaps are core to your workflow, keep Hotjar (or Microsoft Clarity, which is free) and use Nevision for the engineering-side replay + error tracking + uptime.
- **Can I run both Nevision and Hotjar at the same time?**
  Yes — they're independent scripts and don't conflict. Some teams keep Hotjar for marketing and add Nevision for engineering.

### Nevision vs UptimeRobot

URL: https://nevision.app/alternatives/uptimerobot
Category: Uptime monitoring

UptimeRobot is a category-leading freemium uptime tool — 50 free monitors at 5-minute intervals. It does its one job well. The catch: when an alert fires, you still need 4 other tools to figure out what broke. Nevision combines uptime with the rest of the observability stack so the alert and the root cause live on the same dashboard.

**Comparison**

| Feature | Nevision | UptimeRobot |
| --- | --- | --- |
| Free monitors | 1 (15 min) | 50 (5 min) |
| Paid plan starts at | $39/mo | $8/mo |
| Min check interval | 1 min | 1 min (Pro) |
| Multi-region probes | Yes | Pro+ only |
| Includes session replay | Yes | No |
| Includes error tracking | Yes | No |
| Includes RUM | Yes | No |
| Includes server metrics | Yes | No |
| Public status pages | Coming soon | Yes |
| Maintenance windows | Yes | Yes |

**When to choose Nevision**

- You want uptime tied to user impact (replay + errors at the same timestamp).
- You're already paying for Sentry/LogRocket/Datadog and want to consolidate.
- You need server CPU/memory monitoring alongside uptime.

**When to choose UptimeRobot**

- You only need uptime monitoring and nothing else — UptimeRobot is cheaper for the standalone use case.
- You need 50+ monitors at $8/month total budget — UptimeRobot's free tier is hard to beat.
- Public status pages are critical and you need them today.

**FAQs**

- **Will Nevision check my site as fast as UptimeRobot?**
  Yes — both offer 1-minute interval checks on paid plans. We probe from 3+ regions and require 3 consecutive failures before alerting (avoiding false positives from regional networking blips).
- **Can I import my UptimeRobot monitors?**
  We don't have a one-click importer yet. UptimeRobot offers a CSV export of monitors; the CSV columns map closely to Nevision's create-monitor API. A migration script is in the docs.

### Nevision vs Datadog

URL: https://nevision.app/alternatives/datadog
Category: Full-stack observability

Datadog is the gold standard for enterprise observability — and the gold standard for surprise bills. The pricing model (per-host, per-GB, per-feature) creates a constant fight with finance. For startups and mid-sized teams, Datadog is overkill and overpriced. Nevision delivers the 80% of observability that 80% of teams need, at a flat $39 or $99/month.

**Comparison**

| Feature | Nevision | Datadog |
| --- | --- | --- |
| Pricing model | Flat-rate | Per-host + per-GB + per-feature |
| Starts at | $39/mo all-inclusive | $15/host/mo (Infra) + add-ons |
| Predictable monthly bill | Yes | No |
| Session replay | Included | Add-on |
| Error tracking | Included | Add-on |
| Uptime monitoring | Included | Synthetics add-on |
| RUM (Core Web Vitals) | Included | RUM add-on |
| Server metrics | Included | Infrastructure add-on |
| Log management | Included | Logs add-on |
| Distributed tracing (APM) | No | Yes |
| Kubernetes-native | DaemonSet coming Q3 | Yes |
| Self-host option | No | No |

**When to choose Nevision**

- Your Datadog bill is approaching or exceeding what your team's actual observability needs justify.
- You don't need distributed tracing across microservices — most product teams don't.
- You want pricing that doesn't require a spreadsheet to predict.

**When to choose Datadog**

- You're an enterprise running 100+ microservices needing distributed tracing.
- You need Datadog's 600+ integrations and AWS/GCP/Azure deep telemetry.
- Compliance requires SIEM-grade log retention (years).
- You have a dedicated SRE team that uses Datadog's full feature surface.

**FAQs**

- **What does Nevision NOT do that Datadog does?**
  Distributed tracing (APM with spans across services), full Kubernetes-native deployment, SIEM-grade log retention beyond 365 days, deep cloud provider integrations (AWS Lambda telemetry, RDS query insights, etc.), and security monitoring (Datadog SIEM). If any of these are core to your workflow, stay with Datadog.
- **How much could I actually save?**
  Highly dependent. A team paying ~$2,000/month to Datadog for Infra + APM + Logs + RUM might cover their needs with Nevision Business at $99/month. A team paying $200/month for just Infra might find Nevision the same price or slightly more, but with more features.

### Nevision vs FullStory

URL: https://nevision.app/alternatives/fullstory
Category: Session replay + product analytics

FullStory is enterprise-priced session replay and product analytics — powerful, but you talk to a sales rep before seeing pricing, and the contract is annual. Nevision is self-serve, transparently priced, and delivers the core replay + behavior analytics most teams actually use, without the contract.

**Comparison**

| Feature | Nevision | FullStory |
| --- | --- | --- |
| Pricing | $39/mo or $99/mo flat | Custom (talk to sales) |
| Free plan | Yes (500 sessions/mo) | 14-day trial |
| Self-serve checkout | Yes | No |
| DOM-based replay | Yes | Yes |
| Includes error tracking | Yes | Add-on |
| Includes uptime monitoring | Yes | No |
| Funnels | No | Yes |
| Heatmaps | No | Yes |
| AI-powered insights | No | Yes |
| Server CPU/memory metrics | Yes | No |
| Backend log management | Yes | No |

**When to choose Nevision**

- You want to start using replay today without a sales call.
- Your budget is hundreds, not tens of thousands, per month.
- You also need uptime + errors + server metrics — FullStory doesn't ship these.

**When to choose FullStory**

- You need FullStory's funnels, conversion analytics, or AI-powered insights — those are their differentiator.
- You're an enterprise that values dedicated CSMs and annual contracts.
- Your product team has standardized on FullStory's analytics workflow.

**FAQs**

- **Can I get FullStory-level analytics from Nevision?**
  Not today. Nevision shows session replays, error trends, RUM metrics, and uptime — but doesn't have FullStory's funnel analysis, conversion tracking, or behavioral cohorts. If product analytics is your primary use case, pair Nevision with PostHog or Amplitude.
