Error Tracking When You're the Only Developer

You Built It. You Run It. You Monitor It.

You're a solo developer. You built your SaaS, you deployed it, and now it's your job to make sure it doesn't break at 3 AM while you're sleeping. You don't have an on-call rotation because you *are* the on-call rotation.

Error tracking as a solo dev is different from error tracking on a team. You don't need enterprise features, complex alert hierarchies, or role-based access control. You need something that tells you when your app is broken and helps you fix it fast — without consuming your entire evening.

What Actually Matters for Solo Devs

1. Alerts That Respect Your Time

As a solo dev, every alert interrupts whatever you're doing. You need:

• Fatal crash alerts only — via email or a personal Slack channel
• No alert for non-critical errors — you'll check the dashboard during work hours
• Weekly digest — a summary of what happened this week, sent Monday morning

Do NOT set up "alert on every new error." You'll get 50 alerts in the first week and mute the channel forever.

2. AI Analysis (This Is Your Teammate)

On a team, when you don't understand an error, you ask a colleague. As a solo dev, you ask... nobody. This is where AI analysis replaces the teammate you don't have.

Instead of spending 30 minutes tracing through stack frames, you get a plain-English explanation of what went wrong and a suggested fix. For solo devs, AI analysis isn't a nice-to-have — it's your debugging partner.

3. A Dashboard You Check in 2 Minutes

You can't spend 30 minutes triaging errors every morning. Your daily check-in should be:

1. Open dashboard (5 seconds)
2. Health indicator: green? Great. Move on. Yellow/red? Check the top issues. (30 seconds)
3. If there's something urgent, read the AI analysis and fix it. (5-15 minutes)
4. Otherwise, close the tab and build features. (0 seconds)

Total monitoring time: 2 minutes on good days, 20 minutes on bad days.

4. Free Tier That Actually Works

Solo devs often have $0 monitoring budget. A free tier needs:

• A monthly quota that fits a solo project (Bugsly Free: 100 issues; Sentry Developer: 5k errors)
• Error tracking with stack traces (not just counts)
• AI analysis (the feature that saves the most time)
• At least 7 days retention (enough to catch weekly patterns)

Bugsly's free tier includes all of the above. Sentry's Developer plan is free with 1 user and 5k errors, and its Seer AI agent is listed as subscription required (sentry.io/pricing, read 2026-10-30).

The Solo Dev Error Tracking Stack

Here's the complete setup for a solo developer:

Step 1: Install SDK (2 minutes)

Pick your framework, install the package, add your DSN. That's it.

# Example: FastAPI
import sentry_sdk
sentry_sdk.init(dsn="YOUR_DSN")

Step 2: Configure One Alert Rule (1 minute)

One rule: email me when a fatal error occurs. Nothing else.

Step 3: Bookmark Your Dashboard (10 seconds)

Add your error dashboard to your browser bookmarks bar. Check it once in the morning and once after deploying.

Step 4: There Is No Step 4

Seriously. Don't configure source maps, custom breadcrumbs, performance monitoring, or session replay on day 1. You're one person. Add complexity only when you need it.

What to Skip (For Now)

• Performance monitoring — unless your app is visibly slow, skip it
• Session replay — useful when you have users reporting UI bugs, not before
• Custom dashboards — the default view is fine for one project
• Team features — you don't have a team
• SAML/SSO — you're one person
• Multiple projects — start with one, split later if needed

The Solo Dev Triage Process

When you see an error in your dashboard:

1. Read the AI analysis — does it make sense? Is the fix clear?
2. Check event count — happened once? Probably an edge case. Happened 100 times? Fix it now.
3. Check user impact — is it affecting paying customers or just bots?
4. Decide: fix now, fix this weekend, or ignore — there are only 3 options

The temptation as a solo dev is to fix every error immediately. Resist it. Some errors don't matter. An AbortController timeout from a user with bad WiFi is not worth your Saturday morning.

The Budget Breakdown

For most solo projects, a free tier is sufficient for the first year. Upgrade when you start hitting the 100-issues-a-month limit — which means your app has real users, which is a good problem to have.

The Bottom Line

Error tracking for solo devs should be invisible on good days and a 5-minute helper on bad days. Install the SDK, set one alert rule, and check the dashboard once a day. That's it.

Don't let monitoring become a second job. You have features to build.
