DARTASTIC OPEN-SOURCE LICENSING POSTURE

Last updated: 20 May 2026

Owner: Dartastic.io.

This document records (1) which Dartastic code is open source vs. proprietary, and (2) how we comply with the licenses and trademarks of the open-source components we use. Getting this right is a defense: clean compliance denies a larger competitor (or an upstream project) any leverage to challenge the business.

  1. DARTASTIC'S OWN OPEN-SOURCE CODE (APACHE-2.0)

The following are published publicly under the Apache License 2.0 and are intended for broad adoption (and potential CNCF donation):

  • dartastic_opentelemetry_api
  • dartastic_opentelemetry
  • flutterrific_opentelemetry

Contributions to these projects are governed by the Contributor License Agreement, which lets us release contributions under Apache-2.0 and also include them in proprietary offerings.

  1. DARTASTIC'S PROPRIETARY CODE (NOT OPEN SOURCE)

The following remain proprietary and are licensed only under the Commercial License:

  • the Dartastic Pro native runtime engine and Pro Dart/Flutter packages;
  • the Dartastic Symbolizer service;
  • the Dartastic Pub private registry server;
  • Pro Labs dashboard JSON and Dartastic-branded UI we ship.

These are independent programs. They communicate with other components over standard network protocols (e.g., OTLP, HTTP) and do not link or derive from AGPL software, so AGPL copyleft does not reach them.

  1. AGPLv3 COMPONENTS WE OPERATE (HOSTED)

Dartastic Hosted runs Grafana, Loki, Tempo, Mimir, and Pyroscope, which are licensed under AGPLv3. AGPLv3 permits operating the software as a paid network service. Our obligations:

(a) Run upstream as-is wherever possible — no copyleft modification obligation. (b) Publish our white-label patches (CSS, image swaps, grafana.ini overrides, Dockerfile) as a public source repository to satisfy AGPL §13 (the network-use clause). The source offer is surfaced as a footer link on the Hosted cluster UI: "This service runs modified Grafana — get the source at ." (c) Keep our independent programs proprietary — the Pro engine, Symbolizer, Pub server, and dashboard JSON are not modifications of AGPL software and carry no copyleft obligation. A future Grafana plugin that links Grafana's plugin SDK would itself be AGPL, while any Dartastic HTTP service it calls stays proprietary.

  1. TRADEMARK COMPLIANCE FOR THIRD-PARTY MARKS
  • White-label the Grafana UI customers see (logo, wordmark, favicon, page titles). Use neutral product names ("Dartastic Hosted", "Dartastic Observability") in all customer-facing copy, domains, and metatags. Do not use the Grafana name or logo in marketing without written permission from Grafana Labs.
  • Limit references to third-party marks (Grafana, OpenTelemetry, Datadog, Sentry, Honeycomb, Elastic, etc.) to nominative fair use — descriptive body text only, no logos, no product-name incorporation, no implied partnership or certification.
