8 Best European Alternatives to Sentry (2026), Compared

The best European alternative to Sentry is AppSignal (Netherlands): error tracking, performance monitoring, logs, uptime checks and host metrics in one tool, with application data stored in the Netherlands, from €18.25 a month. If you want to keep your Sentry SDKs and only change the DSN, pick Bugsink (Netherlands) – free to self-host, or managed in the EU from $16 a month.

I wrote this ranking for developers and teams who use Sentry today and want their error data with a European company. Sentry is run by Functional Software, Inc. in San Francisco, USA. Sentry does offer an EU data region in Frankfurt, but its own documentation says user accounts, organisation settings, DSN keys, audit logs and cron check-ins are always stored in the US, whichever region you choose. The European tools below are made by companies in the Netherlands, Belgium, Germany, Italy, Denmark and Croatia. I compared twelve error tracking tools and kept eight, with prices, hosting, the languages they cover and what you give up compared with Sentry.

What are the best European alternatives to Sentry?

These are the European error tracking tools I would move to from Sentry, in order. Each one is reviewed below.

1. AppSignal (Netherlands) – errors, performance, logs, uptime and hosts in one plan. Best for most teams leaving Sentry.
2. Bugsink (Netherlands) – works with Sentry’s own SDKs, self-hosted for free. Best drop-in replacement.
3. Flare (Belgium) – error tracking, performance and logs by Spatie. Best for Laravel and PHP.
4. Tideways (Germany) – profiler, monitoring and error tracking, hosted in Germany. Best for PHP performance.
5. Bugfender (Germany) – remote logs, crash reports and user feedback. Best for mobile apps.
6. Inspector (Italy) – PHP monitoring with a free plan, from €15 a month. Best on a small budget.
7. elmah.io (Denmark) – error logging built only for .NET. Best for .NET teams.
8. Shake (Croatia) – bug and crash reports from inside your app. Best for mobile QA.

Sentry alternatives compared

Prices from public pricing pages. Affiliate links and sponsored placements are labelled.

“Data hosted in” shows where each tool’s application or ingestion servers answer from, based on a DNS lookup and an ASN lookup (25 Oct 2026). Where a tool sits behind Cloudflare, the real server location is hidden and I rely on the vendor’s own statement.

How I compared the Sentry alternatives

The order is driven by how much of Sentry you keep after switching, then by data sovereignty, then by price. I weighed five things:

• Sentry feature match – error grouping, stack traces, alerts, performance tracing, logs and uptime checks, and whether Sentry’s SDKs keep working.
• Language coverage – a tool that covers many languages replaces more of Sentry than one built for a single stack.
• Jurisdiction and hosting – where the company is registered and whose network the ingestion endpoint runs on, including any US cloud.
• Price – the cheapest paid plan and what it includes, plus free plans and self-hosting.
• What users say – Trustpilot ratings where a profile exists, read together with the number of reviews.

I left out GlitchTip, which also accepts Sentry SDKs, because it is made by Burke Software and Consulting LLC with no European address on its site, and its hosted app answered from DigitalOcean in the US. Better Stack is run by Better Stack, Inc., a Delaware corporation. Telebugs names no company or country behind it, and Uptrace is an OpenTelemetry APM rather than an error tracker and names no legal entity. All data comes from the vendors’ own pricing, about, legal, privacy and security pages and from Trustpilot, checked on 25 October 2026.

The best European alternatives to Sentry, reviewed

Each tool gets the same treatment: who is behind it, what users say, which parts of Sentry it replaces, pros and cons, and my opinion.

1. AppSignal

The closest European match for Sentry’s feature set – errors, performance, logs, uptime and hosts in one plan

AppSignal B.V. is registered in Amsterdam, the Netherlands (Chamber of Commerce 62960407). Its first commit was in 2012, it was co-founded by Thijs Cadier, Robert Beekman and Roy Tomeij, and it describes itself as an independent, sustainable business with a remote team of about 25. AppSignal says application data is only stored in certified facilities in the Netherlands; its website and push API answer from WorldStream B.V. (AS49981) in the Netherlands, and WorldStream is listed as its hosting sub-processor. Backups go to Amazon Web Services EMEA.

What users say. AppSignal has no Trustpilot profile yet. On its pricing page it shows a 4.8 rating on G2.

What it replaces from Sentry – and what it doesn’t. You get error tracking with backtraces and the deploy that caused each error, performance monitoring, log management with live tail, uptime monitoring with a free public status page, host monitoring, anomaly detection and metric dashboards. It supports Ruby, Elixir, Node.js, front-end JavaScript, Python, Go, Java, PHP and Rust, and it is built on OpenTelemetry. Every plan has unlimited users and apps, and going over your limit does not cost overage fees. What you lose: you replace Sentry’s SDKs with AppSignal’s integrations, there is no session replay, and no native mobile SDK is listed.

Facts: HQ Netherlands (Amsterdam) · first commit 2012 · free plan: 30K requests, 1 GB logs, 5-day retention · paid from €18.25/month billed yearly (€219/year) or €22 monthly, 250K requests · 30-day trial without card · ISO 27001 · US hosting available on request.

Switching from Sentry: moderate – you install AppSignal’s package for your language instead of the Sentry SDK and rebuild your alerts.

My take: AppSignal is my pick because it replaces the most of Sentry: errors, tracing, logs and uptime checks in a single plan, with data kept in the Netherlands on a Dutch hosting provider. It is also cheaper than Sentry Team once you count unlimited users. You do have to swap SDKs, which is why Bugsink is the better choice if you want zero code changes. Best for: web teams that want one European tool for errors and performance. Not for: mobile teams and anyone who needs session replay.

2. Bugsink

A drop-in Sentry replacement – keep your Sentry SDKs, self-host for free or use the managed EU service

Bugsink B.V. is based in Utrecht, the Netherlands (Chamber of Commerce 93064993). It is built by its solo founder and developer, Klaas, and its code carries a copyright from 2023. The managed service stores data in the EU, according to Bugsink. The bugsink.com website itself answered from a Hetzner Cloud address located in Ashburn, USA.

What users say. Bugsink has no Trustpilot profile yet. Its GitHub repository shows about 2,200 stars.

What it replaces from Sentry – and what it doesn’t. Bugsink says it is fully compatible with Sentry’s open-source SDKs, so you switch by changing the DSN. You keep stack traces with local variables, issue grouping, search, trends, resolve and mute, and alerts to Slack, Discord, email and webhooks, plus an API. What you lose: Bugsink is error tracking only – no performance tracing, logs, session replay or uptime checks. The code is source-available under the PolyForm Shield licence, not open source.

Facts: HQ Netherlands (Utrecht) · self-hosted: free, unlimited users, all features · managed: free evaluation with 15K events/month, then $16/month (75K events), $50 (600K), $158 (3M) · managed data in the EU · PolyForm Shield licence.

Switching from Sentry: easy – keep your SDK setup and point the DSN at Bugsink.

My take: Bugsink is the fastest way off Sentry: change the DSN and your errors land in a Dutch tool, on your own server if you want. It sits second because it covers errors and nothing else, so you lose more of Sentry than with AppSignal. Best for: teams that only use Sentry for errors and want to keep their SDKs. Not for: teams that rely on Sentry's tracing and replay.

3. Flare

Error tracking, performance and logs from Spatie – built for Laravel, PHP and JavaScript

Flare is made by Spatie in Antwerp, Belgium, which says it has been building Laravel applications since the framework’s early days. The legal entity is Facade BV, registered under number BE0729.961.919. Flare’s website and ingestion endpoint run behind Cloudflare, and Flare’s pages do not say where its servers are.

What users say. Flare has no Trustpilot profile of its own. Spatie’s website has 3.8/5 from only 2 reviews, which says little about Flare.

What it replaces from Sentry – and what it doesn’t. Every plan includes error tracking, performance monitoring, logs, AI and MCP tools, integrations with GitHub and Slack, and 30 days of retention. For Laravel and PHP teams it covers most of what they use Sentry for. What you lose: Flare is only built for Laravel, PHP and JavaScript, there is no free plan, and Flare does not state its hosting location.

Facts: HQ Belgium (Antwerp) · Hobby $9/month (10,000 errors, 1 project, 1 user) · Standard $29/month (100,000 errors) · Growth $69 · Premium $279 · yearly billing gives one month free · 10-day trial, no card · prices exclude tax.

Switching from Sentry: easy for Laravel apps – install Flare’s package and add your key.

My take: Flare is the most polished choice for Laravel shops, and it bundles performance and logs at prices below Sentry Team. It sits third because it only covers PHP and JavaScript, and Flare does not say where your data is stored. Best for: Laravel and PHP teams. Not for: polyglot stacks or teams that need EU hosting in writing.

4. Tideways

PHP profiling, monitoring and error tracking, hosted in Germany

Tideways GmbH is registered in Bonn, Germany (HRB 22127), with Benjamin Außenhofer (born Eberlei) as managing director. Tideways says the service is hosted in Germany, and its app answered from SysEleven GmbH (AS25291) in Berlin. The marketing website runs behind Cloudflare.

What users say. Tideways has no Trustpilot profile yet.

What it replaces from Sentry – and what it doesn’t. Every plan combines a profiler, performance monitoring and error tracking, with unlimited projects, environments and users and alerts to email, Slack and Microsoft Teams. Its profiler goes deeper into PHP performance than Sentry does. What you lose: Tideways is for PHP only, has no free plan and no front-end error tracking.

Facts: HQ Germany (Bonn) · Team €69/month for 5 million requests, Business €159 · yearly billing 10% off · prices excl. VAT · 14-day trial, no card · soft quotas with no overage charges · pay by card or SEPA.

Switching from Sentry: moderate – you install the Tideways PHP extension and daemon on your servers.

My take: Tideways is the strongest German option for PHP: monitoring, profiling and errors in one place, on German servers. It is fourth because it covers one language and starts at €69 a month. Best for: PHP teams that care about performance as much as errors. Not for: small projects and non-PHP stacks.

5. Bugfender

Remote logging, crash reports and user feedback for mobile and web apps

Bugfender is owned by Beenario GmbH in Walldorf, Germany (HRB 752438, Amtsgericht Stuttgart). Its co-founders are Aleix Ventayol, Jordi Gimenez and Stefan Klumpp. Its log API and dashboard answered from OVH (AS16276) in Frankfurt; the privacy policy also names Wasabi Technologies, a US company, for storage in the EU.

What users say. On Trustpilot Bugfender has 3.7/5 from just 1 review – too few to mean much.

What it replaces from Sentry – and what it doesn’t. Bugfender collects logs, errors and crashes from every device, with symbolicated stack traces, device details and an in-app feedback form. It supports iOS, Android, React Native, Flutter, Unity, JavaScript, React, Angular and Vue. Bugfender says more than 35,000 apps use it. What you lose: crash reporting starts on the paid Team plan, and there is no backend performance tracing.

Facts: HQ Germany (Walldorf) · free plan: 100K log lines a day, 24-hour retention, no crash reporting · Team from $49/month paid monthly (10M log lines, 7-day retention) · Pro from $99 · yearly plans save 30% · on-premises from €3,000/month · ISO 27001.

Switching from Sentry: moderate – you add the Bugfender SDK to your app and ship an update.

My take: Bugfender covers a gap Sentry leaves: full logs from the device, not just the crash. For mobile apps that is often more useful. For backend error tracking it does less, which is why it sits fifth. Best for: mobile teams that need logs from users' devices. Not for: backend teams looking for tracing.

6. Inspector

Real-time PHP monitoring with a free plan and paid plans from €15 a month

Inspector S.R.L. has offices in Naples and Florence, Italy. Its footer names funding from Resto al SUD, an Italian programme for start-ups in the south. Its website and ingestion endpoint run behind Cloudflare, and Inspector does not name a hosting provider; AWS appears among the recipients in its privacy policy.

What users say. Inspector has a Trustpilot profile but no reviews yet.

What it replaces from Sentry – and what it doesn’t. Inspector traces requests and unexpected exceptions in PHP apps, with integrations for Laravel, Symfony, CodeIgniter, Drupal and plain PHP, plus Spring Boot, and an AI bug fixer. Events, hosts and apps are unlimited. What you lose: it is built for PHP, data over your quota is dropped unless you enable usage billing, and hosting is not stated.

Facts: HQ Italy (Naples) · free plan: 30K transactions, up to 3 members · Beginner €15/month (300K) · Developer €39 (800K) · Team €69 (1.5M) · billed monthly.

Switching from Sentry: easy for Laravel and Symfony – install the package and add your key.

My take: Inspector is the cheapest way for a PHP team to get monitoring and exception tracking from an EU company. It ranks below Flare and Tideways because it says less about its hosting and covers fewer Sentry features. Best for: small PHP teams on a budget. Not for: teams that need documented EU hosting.

7. elmah.io

Error logging built only for .NET – but its API runs on Azure in the US

elmah.io ApS is based in Laasby, Denmark, and was founded by Thomas Ardal. elmah.io says it runs on Microsoft Azure, and its API endpoint resolved to Azure’s West US region when I checked. This is a European company running on a US cloud, with the API in the US.

What users say. elmah.io has no Trustpilot profile yet.

What it replaces from Sentry – and what it doesn’t. elmah.io gives .NET teams error logging with Visual Studio integration, deployment tracking, uptime monitoring and heartbeats on higher plans, an MCP server and AI analysis of your logs. elmah.io says it does not use your log data to train large language models. What you lose: it is .NET only, there is no free plan, and your data goes to a US cloud region.

Facts: HQ Denmark (Laasby) · Small Business $26/month (3 users, 10,000 messages) · Business $44 · Business+ $89 · Enterprise $269 · 21-day trial, no card · runs on Microsoft Azure.

Switching from Sentry: easy for .NET apps – install the NuGet package.

My take: elmah.io is a Danish company with a good .NET product, but its API runs on Azure in the US. That cancels much of the reason to leave Sentry, so it sits seventh. Best for: .NET teams that want a small, focused vendor. Not for: anyone choosing a European tool for data residency.

8. Shake

Bug and crash reports from inside your mobile app, from Zagreb

Shake Ltd. is based in Zagreb, Croatia. Its privacy policy says Shake is hosted on Amazon Web Services, and its API answered from AWS (AS16509) in Frankfurt – a European company on a US cloud, with an EU region.

What users say. Shake has no reviews on Trustpilot yet.

What it replaces from Sentry – and what it doesn’t. Shake attaches 71 data points to every user report, and crash reports come with stack traces, logs and steps to reproduce. It has SDKs for iOS, Android, React Native, Flutter and the web. What you lose: it is a bug-reporting tool for apps, not backend error tracking, and the paid plans are expensive.

Facts: HQ Croatia (Zagreb) · free plan: 1 app, 3 members · Premium from $200/month · startups: Premium for $15/month in the first year · hosted on AWS.

Switching from Sentry: moderate – add the SDK to your app and ship an update.

My take: Shake is a useful European tool next to an error tracker, not a full Sentry replacement, so it closes the list. Best for: mobile teams collecting bug reports from testers and users. Not for: backend error tracking.

What European error tracking costs compared with Sentry

Sentry’s free plan has one user, and its Team plan starts at $26 a month billed yearly. Most European tools include unlimited users, and two of them – Bugsink and Inspector – start at about half that price.

Prices as shown on each vendor’s pricing page on 25 October 2026, in the currency shown there. Tideways prices exclude VAT; Flare prices exclude tax.

How to switch from Sentry to a European error tracker

1. List what you use in Sentry. Errors only, or also tracing, replays, cron checks and uptime? That decides between a drop-in like Bugsink and a full APM like AppSignal.
2. Run both in parallel. Add the new tool next to Sentry in staging, or point a second DSN at Bugsink, and compare grouping and alerts for a week.
3. Upload source maps and set up releases. Without them stack traces for front-end code are hard to read in any tool.
4. Recreate alerts and integrations. Rebuild your Slack, email and issue-tracker rules before you switch off Sentry.
5. Remove the Sentry SDK and cancel. Export anything you need first – Sentry’s lookback is 30 to 90 days depending on plan.

Sentry alternatives: FAQ

My verdict: which European error tracker to switch to

Most teams leaving Sentry should go to AppSignal: it covers errors, performance, logs and uptime in one plan, keeps application data in the Netherlands and costs less than Sentry Team once you add users. If you only use Sentry for errors and want to keep your SDKs, Bugsink is the quickest move – change the DSN, self-host for free or pay $16 a month for the managed EU service.

For Laravel and PHP, Flare and Tideways are better fits than any general tool, and for mobile apps Bugfender gives you device logs Sentry does not. Whatever you pick, run it next to Sentry for a week before you remove the old SDK.
