* ✨ Count the application logs as a metric, by logger and level The error panels had no metric to read: they counted log lines in Loki, because the backend published nothing about the errors of the application (the only thing alive in Prometheus was the http listener error count, which measures another thing). Now there is `penpot_log_events_total{logger, level}`. The counter comes from a new component, `app.loggers.metrics/reporter`, which hooks a watch on the log record like the database and mattermost reporters do, but without a thread or a channel: the increment is in memory, so it runs in the watcher itself. Only `warn`, `error` and `fatal` are counted, and only the records that go through `app.common.logging`: the lines a library writes straight to log4j2 are not counted (one in a thousand today). The body of the watcher is wrapped in a `try/catch` that swallows the error on purpose: the watcher fires from the `swap!` of the log record, inside the logging path, so an exception there would reach whoever was logging and would take the logging executor down with it. A test pins that a failing publication does not propagate. The suite removes the reporter (it would count the logs of the tests and the recording of their `mtx/run!`), so a test of its own pins the wiring. The memories carry the counter, its two limits and why the `try/catch` is not noise; the grafana one also brings the notes of this afternoon about the service account, the dashboard search and Cloudflare, which were waiting for a commit. AI-assisted-by: deepseek-v4.1-flash * 📚 Address the review findings on the log-events metric The review of the counter found that the reason written for the `try/catch` was not the real one, so the memory and the comments say now what happens if it is removed: with `::l/sync?` the exception reaches whoever was logging, and on the async path it dies in the uncaught handler of the logging executor -- outside the application's logging -- where the pool replaces the worker, so logging continues and that line is lost. They also say that a publication failing every time is silent: the counter stays flat and nothing is written about it. The rest are small things the review asked for: the test of the `fatal` level (it was in the counted set and nothing verified it), the HELP of the metric naming the three levels, the require of the test without the unused alias that clj-kondo flagged, and the note that the `level` is lowercase here and uppercase in Loki. The grafana memory loses what was said twice: the two pairs of bullets about reading the API (the service account 403s and the search that lies) are merged, the CLIMIT notes are one bullet instead of two, and the four bullets about editing dashboards are grouped in their own section. Its host name is gone as well, which the first line of that file forbids. AI-assisted-by: deepseek-v4.1-flash

Penpot is the open-source design platform for teams that build digital products at scale.
Penpot’s key strength lies in giving you full ownership of your design infrastructure. Built on open source and designed for self-hosting, it puts teams in complete control of their design environment supporting strict compliance and governance requirements. Whether used in the browser or deployed on your own servers, Penpot works with open standards like SVG, CSS, HTML, and JSON.
Real-time collaboration strengthens this foundation, helping teams scale and bring design closer to the product through top-tier capabilities. Additionally, developers feel at home using Penpot, because design is expressed as code, enabling a direct translation and shipping products faster.
Best-in-class native Design Tokens provide a single source of truth between design and development. They ensure consistency, improve collaboration, and make it easier to manage complex design systems.
The MCP server takes it further by enabling multi-directional workflows between design and code. A powerful open API and plugin system makes the workspace programmable, enabling automation, AI-driven workflows, and integrations with the tools and systems you already use.
With CSS Grid and Flex Layout, teams can design responsive interfaces that behave like real code from the start.
Combined, these features turn Penpot into a full-stack design platform for building scalable design systems and fully integrated product development processes.
If your organization is scaling and needs extra support, we’re here to help. Talk to us

Why Penpot
Penpot connects design, code, and AI workflows through a code-based approach, making designs readable by developers and AI via the MCP server. This approach helps teams ship what’s actually designed and manage design systems at scale with powerful design tokens. As a self-hosted, open-source and real-time collaboration platform, Penpot offers full flexibility, security, and ownership without vendor lock-in. Learn more about why Penpot is the platform for your team.
Plugin system
Penpot plugins let you expand the platform's capabilities, give you the flexibility to integrate it with other apps, and design custom solutions.
Designed for developers
Penpot was built to serve both designers and developers and create a fluid design-code process. You have the choice to enjoy real-time collaboration or play "solo".
Inspect mode
Work with ready-to-use code and make your workflow easy and fast. The inspect tab gives instant access to SVG, CSS and HTML code.
Integrations
Penpot offers integration into the development toolchain, thanks to its support for webhooks and an API accessible through access tokens.
Building Design Systems: design tokens, components and variants
Penpot brings design systems to code-minded teams: a single source of truth with native Design Tokens, Components, and Variants for scalable, reusable, and consistent UI across projects and platforms.
Getting started
Penpot is the only design & prototype platform that is deployment agnostic. You can use it in our SAAS or deploy it anywhere.
Learn how to install it with Docker, Kubernetes, Elestio or other options on our website.
Penpot Enterprise
Penpot Enterprise is our paid plan for organizations that need to scale their design work across multiple teams with advanced governance, security, and administration.
