# Tech Companies Build Internal AI Vibe-Coding Platforms Organizations like Ramp and Stripe are developing proprietary AI-assisted prototyping tools for non-engineers. - **Source:** [The Pragmatic Engineer](https://blog.pragmaticengineer.com) - **Published:** 2026-10-15 - **Topic:** [Software & Engineering](https://brifing.si/c/engineering) - **Original article:** - **On Brifing:** https://brifing.si/s/b7161deb-4da5-439a-986f-5e7aeb10fe3c ## Rise of Internal Vibe-Coding Tech companies are increasingly building proprietary AI-assisted prototyping tools, often termed vibe-coding platforms. Ramp developed 'Glass' to enable non-engineers to create complex internal applications. Similarly, Stripe launched 'Harbor' to streamline prototyping. These tools allow employees to build functional software without traditional coding skills, marking a shift in internal development workflows. ## Ramp's Glass Platform Capabilities Ramp's Glass platform functions as an internal AI workspace where knowledge compounds. Users connect internal systems via specific connectors to serve as data sources for their applications. One marketing employee built a custom CRM with over 50 fields and filters, demonstrating the platform's capacity to handle complex, specialized internal business requirements. ## Stripe's Harbor Prototyping Tool Stripe introduced Harbor, an AI-assisted prototyping tool designed to accelerate internal development. A single engineer built the initial version in approximately six weeks. This tool allows teams to generate prototypes quickly while maintaining a clear history of prompts used, facilitating a more efficient and iterative design process for internal software projects. ## Strategic Rationale for In-House Tools Companies prefer building internal tools over using third-party vendors like Lovable or Replit for several reasons. Primary drivers include the ability to safely expose sensitive internal data and ensure strict adherence to corporate design guidelines. Additionally, these tools reduce reliance on external vendors, avoiding lengthy compliance reviews and complex price negotiations. ## Low Investment and High Adoption Developing these platforms requires minimal investment, often taking only a few weeks with a small engineering team. Ramp has integrated Glass into its new hire onboarding process, ensuring widespread adoption across non-engineering departments. This approach proves more effective than forcing employees to adapt to generic third-party software that lacks specific internal context. ## Upskilling Through Internal Development Building internal vibe-coding tools provides significant educational benefits for engineering teams. Engineers tasked with creating these platforms gain deeper expertise in managing AI infrastructure, a highly sought-after skill set. By investing time in these projects, companies effectively train their staff in-house, mitigating the difficulty of recruiting specialized AI infrastructure talent externally. ## Broader Industry Trends The trend of building custom AI-coding harnesses is expanding across mid-sized and large tech firms. As companies seek to optimize internal workflows, many are expected to follow the models established by Ramp and Stripe. This shift prioritizes internal efficiency and data security, moving away from reliance on external vendor solutions for internal tooling. ## Future of AI-Driven Development The emergence of these internal platforms signals a broader evolution in how tech companies manage software production. By empowering non-engineers to build tools, organizations increase operational agility. As AI infrastructure becomes more accessible, the focus will likely remain on integrating these proprietary coding agents into standard corporate workflows to drive productivity. ## Sources covering this story - https://blog.pragmaticengineer.com/the-pulse-new-trend-of-building-internal-vibe-coding-apps-at-tech-companies/ — --- _Summary written by Brifing from the original reporting.
