Sentry Overview

Sentry is the industry standard for error tracking. When your app crashes in production, Sentry captures the full stack trace, browser details, user context, and a breadcrumb trail of events leading up to the error. You find out about bugs before users report them, and the error reports usually give you everything you need to fix the issue.

The free tier is generous for solo developers. 5,000 errors per month, basic performance monitoring, release tracking, and session replay. I've used Sentry on every production app I've shipped. The moment something breaks, I get a Slack notification with enough detail to start debugging immediately. No guessing, no "can you reproduce the steps?" back-and-forth with users.

Plausible Overview

Plausible is a lightweight, privacy-focused alternative to Google Analytics. It tells you how many people visit your site, where they come from, which pages they view, and what devices they use. All without cookies, all GDPR-compliant out of the box, and all in a dashboard that loads in under a second.

I switched to Plausible because Google Analytics felt like overkill for my projects. I don't need funnel analysis or custom event pipelines. I need to know if my blog post is getting traffic and where that traffic comes from. Plausible does exactly that with a single script tag. The dashboard is refreshingly simple. No 47-click journey to find your pageview count.

You can self-host it for free or pay $9/month for the cloud version. Either way, you're not feeding your users' data to an advertising company.

Key Differences

These tools solve completely different problems. Sentry tracks application errors. Your API throws a 500? Sentry tells you the exact line of code. Plausible tracks website traffic. Your blog post is getting 500 visits today? Plausible shows you where those visitors came from. There's almost zero overlap between what they do.

When they matter. Sentry matters when you're building an application with users who interact with features, submit forms, and trigger server-side logic. Plausible matters when you want to understand your audience and optimize your content or marketing. A SaaS app needs Sentry. A blog needs Plausible. Most projects need both.

Privacy stance. Plausible was built around privacy. No cookies, no personal data collection, no consent banners needed. Sentry collects error data which can include user information (IP addresses, emails if you tag them). Sentry is privacy-aware but it's fundamentally a debugging tool, not a privacy tool.

Pricing model. Sentry charges by error volume. Plausible charges by pageview volume. Both have reasonable entry points for solo developers. Sentry's free Developer plan covers 5,000 errors per month for a single user, and the first paid step is the Team plan at $26/month on annual billing with a 50,000-error quota. Plausible starts at $9/month for 10,000 pageviews, with no permanent free cloud tier, or you can self-host the free Community Edition if you have a server.

Setup effort. Plausible is a single script tag in your HTML. That's it. Sentry requires an SDK integration in your application code, which takes 5-10 minutes but involves more configuration. Both are easy, but Plausible is almost zero-effort.

When to Choose Sentry

You're building an application (SaaS, web app, API) that needs error tracking
You want to catch bugs before users report them
Performance monitoring for slow pages and endpoints matters
You need stack traces and debugging context for production issues
Your project is code-heavy and errors directly impact user experience

When to Choose Plausible

You need website analytics without Google Analytics' complexity or privacy issues
You're running a blog, landing page, or content site and want traffic insights
GDPR compliance matters and you don't want cookie consent banners
You want a clean, simple dashboard instead of Google Analytics' overwhelming interface
You're tracking marketing effectiveness and referral sources

The Verdict

You need both. Seriously. They do completely different things, and both are important for running a solo project.

Use Sentry to track errors in your application. Use Plausible to understand your traffic. There's no overlap and no reason to choose between them.

If budget is extremely tight, here's how I'd prioritize. If you have a production app with paying users, set up Sentry first. Catching errors that affect paying customers is more important than knowing your traffic numbers. If you're in the growth phase and need to understand where users are coming from, set up Plausible first.

But honestly, Sentry has a free tier and Plausible is $9/month (or free self-hosted). For most solo developers, running both is completely affordable. I use both on every project and wouldn't drop either one.

By the Numbers (2026)

Specs change, so here is where each tool actually stood when I last checked, with sources at the bottom of this post.

Sentry

Latest server release is 26.5.1, published 2026-05-27. The JavaScript SDK @sentry/browser is on 10.55.0.
The getsentry/sentry repo has 43,992 GitHub stars and 4,709 forks, written mostly in Python.
Adoption is enormous. @sentry/browser pulled 21,873,309 weekly npm downloads and @sentry/node pulled 22,374,369 in the week ending 2026-05-28.
Free Developer plan includes 5,000 errors, 5 million tracing spans, 50 session replays, and 1 cron monitor per month, capped at one user.
Paid plans start at the Team tier, $26/month on annual billing, which raises the error quota to 50,000 and removes the single-user cap. The Business tier is $80/month annual.

Plausible

Latest release is v3.2.1, published 2026-05-15. The official browser helper plausible-tracker is on 0.3.9.
The plausible/analytics repo has 26,621 GitHub stars and 1,564 forks, written in Elixir.
It is a far smaller install base by npm count, which fits its single-script approach. plausible-tracker saw 36,782 weekly downloads in the week ending 2026-05-28, since most users add the hosted script tag rather than the npm package.
Cloud pricing starts at $9/month for the Starter plan covering up to 10,000 monthly pageviews, then Growth at $14/month and Business at $19/month for higher volume and features.
There is no permanent free cloud tier, just a 30-day trial with no credit card required. Annual billing gives you two months free.
Community Edition is free to self-host under AGPLv3 and ships as a single Docker stack. You supply the server and own the maintenance.

A quick read on what those numbers mean. Sentry's npm download counts are roughly 600 times Plausible's, but that is a delivery-method artifact more than a popularity gap. Sentry ships as an SDK you import, so every install shows up in npm. Plausible ships as a script tag pasted into HTML, so most real installs never touch npm at all. The GitHub star counts are the fairer popularity signal, and there Sentry leads about 44k to 27k.

Real Cost at Solo-Dev Scale

These tools price on completely different units, so a single bill is not comparable. What is comparable is the cost of running both on a typical small project. Here is a concrete workload and what it actually costs from the published rates.

Assume one production app and one content site that together generate fewer than 5,000 errors per month and around 10,000 pageviews per month. That is a realistic month for a small SaaS plus its marketing blog.

Sentry: the free Developer plan covers 5,000 errors per month, so error tracking is $0 as long as you stay a single user. Cost: $0/month.
Plausible: the Starter plan at $9/month covers 10,000 pageviews. Cost: $9/month, or $7.50/month equivalent if you pay annually and take the two-months-free discount.

Combined, running both at this scale is about $9/month on monthly billing, or roughly $90/year if you take Plausible's annual discount. There is no Sentry charge until you exceed the free quota or need a second seat.

Now scale up. Say the app grows to 40,000 errors per month and the site to 9,000 pageviews per month.

Sentry: 40,000 errors still fits under the Team plan's 50,000-error quota, so you move from free to $26/month annual, mostly because you want the higher quota and headroom. Cost: $26/month.
Plausible: 9,000 pageviews still fits the $9/month Starter tier. Cost: $9/month.

Combined at that scale: about $35/month. The honest takeaway is that the analytics bill is the flat, predictable one, and the error bill is the one that steps up as your app gets busier. For most solo projects you can run both for the price of one lunch a month, and the free-self-host route on Plausible can drop the analytics line to $0 if you already pay for a server.

If you want to avoid recurring cost entirely on the analytics side, Community Edition is genuinely free, but budget for the maintenance time. You are now the on-call admin for the Docker stack, the database, and upgrades like the jump to v3.2.1.
