Bilis is a Core Web Vitals monitoring tool focused on real-world website performance. It emphasizes Real User Monitoring, collecting data from actual visitors rather than bots. Integration requires only a single script tag, with the goal of getting deployed in around 3 minutes. It tracks metrics including LCP, INP, CLS, FCP, TTFB, and FID, and provides P75 and P95 percentiles, making it useful for evaluating the actual user experience instead of relying solely on lab tests like Lighthouse.
Feature-wise, Bilis focuses on frontend performance monitoring. It can break data down by route to identify which pages are getting slower, and filter by country, device, and browser to help pinpoint the source of performance issues. It also supports email alerts triggered by thresholds. The integration is very lightweight: the example shown is a defer script tag, and the script is claimed to be under 1KB. On privacy, Bilis says it uses no cookies, requires no consent banner, and is GDPR-compliant, which is especially valuable for websites serving users in Europe.
Pricing is straightforward: the Free plan is $0/month and includes 10,000 pageviews, 1 project, and 7 days of retention; Pro is $9/month and includes 100,000 pageviews, 5 projects, 90 days of retention, and email alerts; Team is $29/month and includes 1M pageviews, unlimited projects, and 1 year of retention. The page also compares a 100K pageviews/month scenario with DebugBear and Datadog, highlighting Bilis’s lower cost. Based solely on the information provided on the page, Bilis appears to offer strong value for money, especially for teams with limited budgets that still need real-user Web Vitals data.
The main advantages are simple deployment, a lightweight script, low pricing, a free tier, and a fairly complete set of Core Web Vitals-focused analysis dimensions. Its cookie-free design also reduces the compliance burden during implementation. The limitation is that relatively little information is disclosed: it does not say whether the product is open source or supports self-hosting, and there is no visible mention of APIs, SDKs, webhooks, data export, third-party integrations, SLA, or support channels. It looks more like a lightweight monitoring tool dedicated to performance metrics rather than a replacement for full observability platforms such as Datadog.
Bilis is suitable for indie developers, small and midsize SaaS teams, content sites, marketing sites, and frontend teams that want a low-cost way to monitor real-user page performance. If you need logs, error tracking, backend APM, or complex alerting workflows, you will likely still need to combine it with other tools. The page does not provide information about access from mainland China, and payment methods are also not disclosed. For teams using it from China, it is recommended to first test the connectivity of the bilis.app script and dashboard, verify billing and payment availability, and evaluate DebugBear, Datadog, or a self-built Web Vitals collection setup as alternatives.
