Sourcegraph

Sourcegraph is a software company focused on helping developers understand, search, and modify large software codebases. Its technology semantically indexes source code across repositories, programming languages, file formats, and hosting environments, allowing users to search code and navigate relationships that are difficult to identify with ordinary text-search tools. The company’s customers and users have included organizations managing large commercial codebases as well as developers working with open-source and personal repositories. Sourcegraph was founded by Stanford graduates Quinn Slack and Beyang Liu. The product was first released in 2013 under the Sourcegraph name. Liu’s earlier experience using Google Code Search helped inspire the idea of a more capable system for searching and understanding software distributed across multiple repositories. The founders described the challenge as the “big code problem”: the difficulty of maintaining and comprehending code at organizational scale, particularly when projects span many services, programming languages, and repositories. The company initially emphasized self-hosted deployment, allowing customers to operate the platform on their own infrastructure. Early customers reportedly included Uber, Dropbox, and Lyft. Over time, Sourcegraph expanded its integrations with code-hosting and development systems, including GitHub, GitLab, Codecov, and Jira Software. Its search technology supports more than 30 programming languages and uses relevance-ranking techniques, including a variant of PageRank, to help users find useful results in large code collections. The product and licensing strategy changed several times. Sourcegraph’s code was initially available under open or source-available arrangements, and the company moved to the Apache License 2.0 in 2018. In 2023, the principal code-search product was renamed Code Search as the company introduced Cody, an AI-oriented coding assistant. That year, much of the code was moved from the Apache license to a proprietary Sourcegraph Enterprise license, prompting criticism from parts of the developer community. In August 2024, the main repository was made private, ending the prior source-available model for the principal product. Sourcegraph broadened access through a browser-based portal in 2021, enabling users to browse open-source projects and personal private code. In 2022, it introduced Sourcegraph Cloud, a commercial single-tenant cloud offering aimed at organizations with more than 100 developers. In 2023, the company introduced Cody, which assisted with writing and maintaining software through integrations for Visual Studio Code and JetBrains IDEs. As the product portfolio evolved, the original Sourcegraph product became known as Code Search, while Cody served as the AI coding application. In 2025, Sourcegraph announced major changes to its AI product strategy. New Cody Free, Pro, and Enterprise Starter accounts were discontinued in July 2025, while Cody Enterprise remained available for existing enterprise customers. The company introduced Amp, an AI coding agent capable of generating code and documentation, writing tests, and carrying out refactoring tasks. Amp was offered through web, command-line, and integrated-development-environment interfaces and used a credit-based pricing model. In December 2025, Sourcegraph announced that Amp would be spun off as a separate company. The available reference material does not establish the resulting ownership structure or the company’s current headquarters.

Sourcegraph was established by Stanford graduates Quinn Slack and Beyang Liu to address the difficulty of searching and understanding large, distributed software codebases. The concept was partly influenced by Liu’s exposure to Google Code Search during an internship. Rather than limiting search to one repository or one programming language, the founders pursued a system capable of indexing and analyzing code across multiple projects, file types, and development environments. The first version of the product appeared in 2013 under the Sourcegraph name. Its early deployment model was self-hosted, with customers running the service on their own infrastructure. This approach suited organizations with large or sensitive codebases and helped the company attract early users such as Uber, Dropbox, and Lyft. The product combined repository-wide search with code intelligence and navigation features intended to show how software components relate to one another. Sourcegraph’s licensing model became an important part of its early identity. In 2016, the company faced criticism over its use of a Fair Source License. The company argued that publicly available and modifiable code could coexist with a commercial model that helped developers earn revenue. In 2018, Sourcegraph OSS adopted the Apache License 2.0. The commercial Enterprise edition continued to use separate licensing terms. The company expanded its integrations and distribution. In 2019, Sourcegraph functionality was integrated into GitLab’s codebase, giving GitLab users access to browser-based code search and developer-oriented features. In 2021, Sourcegraph made a browser-based portal available for browsing open-source projects and personal private code. The company also reported substantial scale by that period, with approximately 800,000 developers using the platform and about 54 billion lines of code indexed, according to the cited reference material. In 2022, Sourcegraph introduced Sourcegraph Cloud, a commercial single-tenant cloud service aimed at organizations with more than 100 developers. This extended the company beyond self-managed installations while preserving an enterprise-oriented deployment model. The company also raised venture financing, including a reported $125 million Series D round in 2021. Financial amounts are not repeated here as the available material does not provide a direct financial source suitable for this dossier. A major repositioning occurred in 2023. Sourcegraph introduced Cody, an AI coding assistant for writing and maintaining software, and renamed the established Sourcegraph product Code Search. Code Search continued to provide semantic search and code intelligence, while Cody represented the company’s move into generative AI and integrated developer assistance. The licensing strategy changed at the same time: most of the Code Search code moved away from the Apache License to a proprietary Sourcegraph Enterprise license. In August 2024, the main repository became private, further separating the commercial platform from its earlier open-source presentation. Sourcegraph changed direction again in 2025. New Cody Free, Pro, and Enterprise Starter accounts were discontinued in July, with Cody Enterprise continuing for existing enterprise customers. The company launched Amp, an AI coding agent designed to generate code and documentation, write tests, and perform refactoring. Amp was distributed through web, command-line, and IDE channels and used credit-based pricing. In December 2025, Sourcegraph announced that Amp would be spun off into a separate company. The available reference does not specify the final corporate structure, leadership, or relationship between Amp and the remaining Sourcegraph business.
