Organise
A workspace for every client
Keep each client’s Sites, people and reports separate, and see them all from one account.
A Team for each client
Each Team is a workspace for one client: their Sites, their competitors, their leaderboards and their monthly reports. Move a Site between Teams without losing its history when an account changes hands.
Learn about Teams →Read-only access for clients
Invite client stakeholders to their workspace as Viewers. They see their own comparisons, metrics and reports, and receive email reports, without being able to change your monitoring setup.
Learn about roles →Report
Prove the results of your work
Show clients what changed and why, every month, without building a report.
Monthly Team Insights for every client
Every member of a client Team gets a monthly summary of each Site: rated Regressed, Improved or Stable, with the Core Web Vitals assessment and the metrics that changed.
Learn about Team Insights →Before and after every release
Deploy markers show exactly when your work shipped. Compare each deployment with the one before it, for real visitors and in synthetic tests, so the improvement is plain to see.
Learn about deploy tracking →Protect
Catch regressions before your client does
Set the standard for each client, then let Calibre tell you when a release breaks it.
Performance budgets per client
Set budgets on the metrics each client cares about. Send alerts to email, to each client’s own Slack channel, or anywhere else with webhooks.
Learn about budgets →Pull request reviews
Calibre tests the preview deployment of each pull request, from Vercel, Netlify, Render or any public URL, so you see the performance impact of a change before it reaches the client’s visitors.
Learn about pull request reviews →Win work
Rank clients against their industry
Bring real numbers to the pitch, then show clients how far they have climbed.
A full performance picture from one URL
Add a prospect’s site and Calibre scans it for its most important pages, pulls their Google CrUX data and runs Lighthouse tests, with nothing to install on their site.
Learn how adding a Site works →A leaderboard in every client workspace
Add a client’s competitors to their Team and Calibre ranks them all on real-user data. Show where they stand before you start, and where they rank as your work ships.
Learn about Teams →“Guaranteeing our clients good performance and delivering best practices has never been easier for us.”
Questions from agencies
Can I monitor all of my clients’ sites from one Calibre account?
Yes. Every Calibre plan includes unlimited Sites and URLs. On the Team plan and above you can also create unlimited Teams, so each client gets a Team with its own Sites, members and reports.
Can clients see their own data without seeing other clients?
Yes. Add client stakeholders only to their own Team. People only see the Teams they belong to. Give them the Viewer role and they can view metrics and reports, run tests and receive email reports, but cannot change monitoring settings.
How does Calibre report performance to clients?
Each month, Calibre emails a Team Insights report to every member of a Team. It covers every Site in the Team, rates each one as Regressed, Improved or Stable, and includes the Core Web Vitals assessment, significant metric changes, CrUX data and synthetic Web Vitals. Members can also opt in to a weekly or monthly Insights report for each Site.
Can I check a prospective client’s site before they sign?
Yes. Add the prospect’s site to Calibre with a single URL. Calibre scans the site to find its most important pages, matches them against Google’s Chrome User Experience Report (CrUX), and runs synthetic Lighthouse tests. Within about 30 minutes you have Core Web Vitals for each page, how real visitors experience the site by country and device, and audits that point to the issues slowing it down. Nothing needs to be installed on their site.
Can I show a client how they compare with their competitors?
Yes. Create a Team for the client, which acts as their workspace, and add their competitors’ sites alongside their own. Calibre ranks every site in the Team on Google CrUX data, and the client can see the comparison with Viewer access. Calibre keeps collecting data from the day a site is added, so the ranking builds into a record of progress over time.
How do I stop a release from slowing down a client site?
Set performance budgets on the metrics that matter for each client and get alerts by email, Slack or webhook when a budget is at risk or exceeded. Pull request reviews test the preview deployment of each pull request (from Vercel, Netlify, Render or any public URL) and show the performance impact before a change ships.
How is Calibre priced for agencies?
Plans are not priced per Site. Usage is measured in synthetic tests (one URL and Test Profile combination, multiplied by the test schedule) and real user sessions. Each plan includes a number of seats, and client Viewers use a seat. The Team plan includes 10 seats, with more available as add-ons.
