The Real Question Isn’t Which Tool — It’s Who’s On Call at 2 AM

Every production app breaks. The difference between a midnight page and a quiet morning is whether you have error tracking in place before you need it.

For indie developers and solo founders, the decision between a managed SaaS like Sentry and a self-hosted alternative isn’t just about pricing — it’s about what kind of operational burden you’re willing to carry. This guide walks through that trade-off honestly, without pretending either path is free.

What Error Tracking Actually Does (And What It Doesn’t)

Error tracking tools catch exceptions in real time, attach stack traces and runtime context, group duplicate occurrences into a single issue, and alert you when something breaks. They tie errors to specific releases and commits so you know what changed. That’s the job.

What they don’t do: they won’t catch outages that produce zero exceptions. For that you need uptime monitoring — a different tool for a different question. Mature solo operators run both, but they start with error tracking because it tells you what in your code broke, not just that your site is down.

The Managed Path: Sentry and the Pay-Per-Event Model

Sentry is the default answer for most web and backend teams. It has the broadest SDK coverage, the most mature source-map and stack-trace experience, and a workflow that runs from error capture to resolution without leaving the platform. That convenience has a cost structure that can surprise you.

Sentry’s pricing is usage-based by events, not by user or per project. An event is any error, transaction, replay, or attachment the platform ingests. The free Developer plan includes 5,000 errors per month and 50 session replays. The Team plan starts at $26 per month (billed annually) and includes 50,000 errors and 50 replays. The Business plan is $80 per month with the same 50,000-error cap. Everything past those quotas bills at pay-as-you-go rates.

The catch isn’t seats anymore — it’s quotas. A single noisy deploy can eat through your monthly allowance. A background job that retries and fails repeatedly generates events just like a user-facing crash. Session replay, while useful, counts against the same limit.

For a solo founder with a low-traffic side project, Sentry’s free tier may be enough. Once you hit production traffic that generates consistent errors, the math changes quickly. And if you’re shipping a mobile app with frequent crash reports, those event counts climb faster than most indie developers expect.

The Self-Hosted Path: Your Server, Your Quotas, Your Maintenance

Self-hosted error tracking means running the tool on your own infrastructure. The trade-off is straightforward: you trade monthly event costs for your own time and server costs.

GlitchTip is the lightest option. It speaks Sentry’s SDK wire protocol, which means you can keep using the Sentry client libraries you already have in your codebase and simply point them at your own server. It runs on a single small VPS with as little as 512 MB of RAM. There’s no Kafka, no ClickHouse, no complex dependency chain. You deploy it, you point your SDK at it, and you stop paying per event.

Temps takes a different approach. It also exposes a Sentry-compatible DSN, so migration is literally changing one URL in your existing SDK configuration. But it bundles analytics, session replay, uptime monitoring, and git-push deploys into a single Rust binary. It’s free to self-host, which means you get more features than GlitchTip without additional cost — but you also take on the maintenance of a slightly more complex stack.

SigNoz and HyperDX are OpenTelemetry-native platforms. They unify errors with traces and logs under a single OTel pipeline. This is a fundamentally different trade-off than a Sentry-DSN drop-in: both require instrumenting your code with OpenTelemetry SDKs rather than swapping a DSN. If you’re already invested in the OpenTelemetry ecosystem, this path makes sense. If you’re not, the migration cost is real.

The Hidden Cost of Self-Hosting: It’s Not Just Server Bills

Running your own error tracker sounds simple until you’re the one patching it at 2 AM because an update broke your ClickHouse queries, or you’re debugging why your Sentry-compatible self-hosted instance stopped ingesting events after a Docker Compose restart.

The maintenance burden varies by tool. GlitchTip, being Django-based and lightweight, is comparatively low-maintenance. Temps, with its bundled analytics and replay features, has more moving parts. SigNoz and HyperDX, as full observability platforms, carry the most operational overhead.

For a solo founder, your time is the scarcest resource. Every hour spent maintaining your error tracking stack is an hour not spent on product, customers, or revenue. That doesn’t mean self-hosting is wrong — it means you should be honest about what you’re buying with those server bills.

When Self-Hosting Actually Makes Sense

Self-hosted error tracking earns its keep in three scenarios:

Data residency and control. If you’re handling sensitive user data and need to keep error information on your own infrastructure — for compliance, privacy policy, or simply because you don’t trust a third party with your stack traces — self-hosting is the answer. No managed platform can match the control you have when the data never leaves your server.

Predictable cost at scale. If your error volume is high and consistent, self-hosting often becomes cheaper than managed pricing. A $10-per-month VPS handles far more events than Sentry’s free tier, and you’re not surprised by a spike in background job failures. The cost is predictable because it’s fixed.

You already run infrastructure. If you’re comfortable managing Docker containers, keeping things updated, and troubleshooting at odd hours, self-hosting is a natural extension of what you already do. The marginal cost of adding another container is low when you’re already in the habit.

When Managed SaaS Is the Right Call

Managed error tracking is the right choice when:

You want to ship, not maintain. If your product is your code, not your infrastructure, a managed service lets you focus on what you built. Sentry, Rollbar, Bugsnag, and Honeybadger all handle the operational burden so you don’t have to.

Your error volume is low and unpredictable. If you’re a solo founder with a side project that gets occasional errors, paying $26 per month for Sentry’s Team plan is often cheaper than the time you’d spend setting up and maintaining a self-hosted instance. The math works in managed’s favor when events are infrequent.

You need mobile or cross-platform depth. Bugsnag is the specialist for mobile and release-health, with class-leading native symbolication and stability scoring. If your app runs on iOS and Android, the managed mobile-first tools often outperform self-hosted options out of the box.

You’re already on a platform. If you use Datadog for APM or New Relic for monitoring, their error tracking is one layer in a wider stack. Adding a separate tool creates context-switching overhead. Staying platform-native keeps your observability unified.

A Practical Decision Framework

Before you choose, answer two questions:

What’s your stack’s center of gravity? Web-first (JavaScript, Python, Ruby, Go, PHP)? Sentry or a Sentry-compatible self-hosted option is the natural fit. Mobile-first (iOS, Android, React Native, Flutter)? Bugsnag deserves serious consideration. Already on an observability platform? Staying native probably makes sense.

What’s your team’s real bottleneck? Can’t see the errors? Any tool solves that — pick by stack fit and price. Drowning in error noise? You need intelligent grouping and triage workflow — Rollbar and Honeybadger are sharp here. Can’t tell if a release is healthy? You need release-health and stability scoring. Error spend is too high? You need a focused tool, not a platform — standalone tools are almost always cheaper at volume than full observability platforms.

The Migration Reality

If you’re currently on Sentry and considering self-hosting, the migration is easier than you might think — if you pick the right tool. GlitchTip and Temps both accept Sentry-compatible DSNs, meaning you change one URL in your SDK configuration and your error data starts flowing to your own server. Your existing SDK code stays intact. The transition is a configuration change, not a rewrite.

If you’re considering SigNoz or HyperDX, the migration is deeper. You’d need to re-instrument your code with OpenTelemetry SDKs. That’s a real engineering effort, not a URL swap. Factor that into your decision.

The Bottom Line

There is no universal winner. The right choice depends on your error volume, your stack, your tolerance for operational work, and how much you value data control versus convenience.

If you’re a solo founder shipping a web app with modest traffic and occasional errors, Sentry’s free tier or a low-cost managed plan like Honeybadger may be all you need. If your error volume is high, your data is sensitive, or you’re already comfortable running infrastructure, self-hosting with GlitchTip or Temps is a rational choice that pays for itself in predictable costs and full control.

The worst decision is buying a platform when you needed a specialist, or a specialist when you needed the platform. Know what you’re optimizing for — time, cost, or control — and pick the tool that matches that priority.

FAQ

Is self-hosted error tracking actually free? The software is free, but you pay with server costs and your time. A $5–10 per month VPS covers the infrastructure, but factor in the hours you’ll spend deploying, updating, and troubleshooting. For a solo founder, that time has a real opportunity cost.

Can I switch from Sentry to a self-hosted tool without rewriting my code? With GlitchTip or Temps, yes. Both accept Sentry-compatible DSNs, so you change one URL and keep your existing SDK integration. With OpenTelemetry-native tools like SigNoz, you’d need to re-instrument your code.

What’s the cheapest option for a solo developer with low error volume? Sentry’s free Developer plan (5,000 errors per month) is the cheapest starting point. If you need a bit more headroom, Honeybadger’s flat-rate plans offer predictable pricing without event-based billing surprises.

Does self-hosting actually save money at low event volumes? Usually not. If you’re generating fewer than 10,000 errors per month, the server cost plus your maintenance time typically exceeds what you’d pay on a managed plan. Self-hosting earns its keep at higher, more consistent volumes.

What about session replay — do I need it? Session replay is useful for understanding the user journey that led to an error, but it counts against your event quota on most managed platforms. If replay is important to you, a self-hosted option like Temps that bundles it without per-event billing may be worth the operational trade-off.
