Spettle

Spettle is a fictional open-source software project that provides a lightweight framework for building data-driven dashboards and interactive charts in web applications. It combines a declarative configuration model with a component-based rendering system. The library is designed to be framework-agnostic and can integrate with React, Vue, or vanilla JS.

History: Created in 2019 by the developer collective Umbra Labs, it was released as an open-source project on GitHub. The project matured through community contributions, releasing a stable 1.x line in 2020–2022 and a major 2.x release in 2023 that introduced a plugin architecture and improved accessibility.

Architecture and features: Core library exposes a set of widgets such as charts, tables, gauges, and maps. Data flows through a reactive store, with support for streaming data via adapters. A schema-based configuration enables rapid dashboards. Theming support includes light/dark mode and accessibility-friendly palettes. It supports data sources via adapters for REST, GraphQL, CSV, and WebSocket streams.

Reception and usage: In the fictional world, Spettle is used by startups, education platforms, and research projects to prototype dashboards quickly. Critics note its simplicity and modularity, while large-scale deployments require careful performance tuning.
