Glass Devtools, Inc.
Glass Devtools develops Void, an open-source AI code editor that enables developers to write code with AI assistance while maintaining complete control over their data. Unlike proprietary alternatives, Void allows direct connection to any LLM or local model hosting.
Founding Story
Andrew and Mathew Pareles founded Glass Devtools in 2024 after their previous venture, DeriveIt (a tech interview prep site). They initially created Glass.js, an early AI coding tool that allowed developers to edit websites in plain English without leaving the browser. However, they discontinued Glass.js to focus on a more ambitious project: Void Editor. The motivation behind Void was to address privacy and cost concerns associated with proprietary AI coding tools like Cursor and GitHub Copilot. They wanted to create an open-source alternative that would give developers full control over their data by allowing direct connection to any LLM or local model hosting. The founders were accepted into Y Combinator's Summer 2024 batch and launched Void in October 2024, releasing the first beta in January 2025.

Business Model
Revenue Model
Open-source software with no direct revenue model disclosed. Void Editor is free and open-source (Apache 2.0 license). The company does not charge for the software itself. Users pay directly to AI model providers (OpenAI, Anthropic, etc.) for API usage, or can host models locally for free. Unlike competitors like Cursor ($20-40/month subscriptions), Void eliminates the middleman subscription layer. The business model for monetization has not been publicly disclosed, though common open-source strategies include enterprise support, hosted versions, or premium features.
Pricing Tiers
Void Editor is completely free and open-source under Apache 2.0 license. Users can download, modify, and use without any subscription fees. Users pay only for their chosen AI model API costs (if using cloud models) or nothing if using local models via Ollama.
Target Markets
- Individual software developers and engineers
- AI researchers and machine learning practitioners
- Development teams prioritizing data privacy and security
