AppSignal Review (2026): Dutch Error Tracking and APM from €18.25 a Month

What is AppSignal?

Who is behind AppSignal

AppSignal is an application monitoring tool from AppSignal B.V., registered in Amsterdam, the Netherlands, under Dutch Chamber of Commerce number 62960407. Its first commit was in 2012, and its co-founders are Thijs Cadier, Robert Beekman and Roy Tomeij. AppSignal describes itself as an independent and sustainable business and as a remote company of about 25 people, with team members in Greece, Latvia, the Netherlands, Pakistan, Portugal, Spain, the United Kingdom and the United States.

AppSignal calls itself the only EU-based APM. It is aimed at developers who want error tracking and performance monitoring in one place, and it supports Ruby (on Rails), Elixir, Node.js, front-end JavaScript, Python, Go, Java, PHP and Rust, with dedicated pages for Next.js, Laravel and Symfony. Newer integrations are built on OpenTelemetry.

Where AppSignal hosts your data

AppSignal’s privacy policy says the application data you send is only stored in ISO 27001, ISO 9001, ISO 14001 and PCI DSS certified facilities in the Netherlands. Its security page names WorldStream B.V., a Dutch provider, for hosting, and Amazon Web Services EMEA SARL for backups. The DNS check matches: the website, the push API and the ingestion endpoint all answer from WorldStream’s network (AS49981) in the Netherlands, not from a US cloud. Customers who need it can ask for US hosting instead.

AppSignal pricing

AppSignal has a free plan and one paid plan that scales with volume. The Free plan is permanent and gives you 30K requests, 1 GB of logging and 5 days of retention. The paid plan starts at €219 a year billed yearly (€18.25 a month) or €22 billed monthly for 250K requests a month and 1 GB of logs; in US dollars it is $279 a year. Long-term log storage to your own S3-compatible bucket and HIPAA compliance are add-ons at €89 a month each on yearly billing (€99 monthly). There is a 30-day free trial without a credit card.

Two details make the bill predictable: every plan has unlimited users, teams, applications and dashboards, and AppSignal does not charge overage fees – if you stay above your limit during a 30-day review, your plan is upgraded instead. Open-source and humanitarian projects can get extended limits for free. Compared with Sentry, whose Team plan costs $26 a month billed yearly for 50k errors, AppSignal is cheaper at the entry level and includes performance, logs and uptime checks.

Features: errors, performance and more

Error tracking records every exception and occurrence with the backtrace and the deploy that shipped it, and front-end JavaScript errors are covered too. Performance monitoring shows response times, throughput and slow endpoints. Log management adds full-text search, attribute filters, saved queries and live tailing. Uptime monitoring pings from four locations and includes a free public status page, and host monitoring tracks CPU, disk, load, memory and network. Anomaly detection and metric dashboards complete the set.

AppSignal lists ISO 27001 certification, GDPR and HIPAA compliance, and penetration tests run as part of its ISO 27001 programme. What it does not have compared with Sentry: session replay, a native mobile SDK, or compatibility with Sentry’s SDKs, so switching means installing AppSignal’s own integration.

What users say about AppSignal

AppSignal has no Trustpilot profile yet (checked 25 October 2026). On its own pricing page it shows a 4.8 rating on G2. Without independent reviews in volume, I would rely on the free plan and the 30-day trial to judge it.

Pros and cons

Verdict on AppSignal

Verdict: AppSignal is the most complete European alternative to Sentry: error tracking, tracing, logs, uptime checks and host metrics in one plan, from a Dutch company that stores your application data in the Netherlands on a Dutch provider. Pricing is simple, users are unlimited and there are no overage bills. The trade-off is that you replace your Sentry SDK and give up session replay. Best for: web and backend teams that want errors and performance in one European tool. Not for: mobile-first teams and anyone who needs session replay.

AppSignal is ranked #1 in Best European alternatives to Sentry and in Best European error tracking tools.
