Sourcegraph is a code search and code intelligence tool that semantically indexes and analyzes large codebases so that they can be searched across commercial, open-source, local, and cloud-based repositories.[1] Sourcegraph supports all major programming languages.[2]

History

Stanford graduates Quinn Slack and Beyang Liu founded Sourcegraph in San Francisco, California, in 2013.[3][4]

Partly inspired by Liu’s experience using Google Code Search while he was a Google intern,[5] Sourcegraph was developed to “tackle the big code problem” by enabling developers to manage large codebases that span multiple repositories, programming languages, file formats, and projects.[6] The platform can be used to search and analyze all of an organization’s code.[4]

To begin with, Sourcegraph customers self-hosted the platform on their own infrastructure.[7] Early customers included Uber, Dropbox, and Lyft.[7][8]

Prior to 2016, Sourcegraph began indexing “hundreds of thousands” of open-source repositories,[9] reporting in 2021 that they had indexed over 1,000,000.[10]

In 2016, Sourcegraph collaborated with technology licensing lawyer Heather Meeker to develop the Fair Source License,[11][12][5] announcing in May 2016 that “all of Sourcegraph’s source code is publicly available and hackable, under the Fair Source License.”[13] The license aimed to “help open sourcers strike a balance between getting paid and preserving their values,”[14] but came under fire for undermining open-source licensing.[15]

In 2018, Sourcegraph became an open-source project under the Apache License 2.0.[16][17] Sourcegraph has since released Sourcegraph OSS under the Apache License 2.0 and Sourcegraph Enterprise under its own license.[18]

In 2019, Sourcegraph integrated into the GitLab codebase, which gave GitLab users access to a browser-based developer platform.[19]

As of July 2021, some of Sourcegraph’s customers include Adidas, Lyft, Uber, Yelp,[20] Plaid, GE, Atlassian,[21] Amazon, PayPal, Qualtrics, and Cloudflare.[6]

Sourcegraph integrated its code search platform with cloud-based technology in August 2021, launching a browser-based portal that anyone can use to search open-source projects and personal private code for free.[7] Sourcegraph Cloud, a single-tenant cloud solution for organizations with over 100 developers, was launched in 2022, marking a shift in the company’s business model toward a SaaS model.[22][7]

In October 2022, Steve Yegge joined Sourcegraph as Head of Engineering.[23]

Applications

In research, Sourcegraph has been applied to develop data mining methods for downstream dependencies[24] and to aid in the refactoring and translation of a program into its equivalent in a different programming language.[25]

Sourcegraph is used in the CERN Accelerator Control software community to index code, quickly search through it, and create statistics.[26]

In cybersecurity, Sourcegraph has been used for better insights into source code during penetration tests.[27]

Services

The core Sourcegraph product has two versions:[28]

  • Sourcegraph Open Source (Sourcegraph OSS), which is free to use and only includes Sourcegraph’s universal code search functionality.
  • Sourcegraph Enterprise (previously Sourcegraph Data Center[16]), which includes the Sourcegraph code intelligence platform and has a free tier for a limited number of users.

Code can be searched and navigated from the Sourcegraph web UI or using browser and IDE extensions and text editor plugins.[1] Sourcegraph supports over 30 programming languages and integrates with GitHub and GitLab for code hosting, Codecov for code coverage, and Jira Software for project management.[20]

Sourcegraph's "universal code search" tool is used to search, explore, and understand code.[3][29] Search can be implemented across multiple repositories and code hosting platforms. Search can be literal, regular expression, or structural. Structural search syntax is language-aware and handles nested expressions and multi-line statements better than regular expressions.[1] Sourcegraph's Code Search uses a variation of Google's PageRank algorithm to rank results by relevance.[30]

Code Navigation

Sourcegraph's Code Navigation feature can be used to jump to the definition of a variable or function, or find all references to it in a codebase.[1]

Batch Changes

Sourcegraph's Batch Changes feature allows developers and companies to automate and track large-scale code changes across repositories and code hosts.[31]

Code Insights

Sourcegraph's Code Insights feature extracts data from a codebase to provide detailed analytics and visualizations to track the state and progress of a code project.[32]

Growth

Sourcegraph has raised a total of almost $225 million in financing to date. Its most recent $125 million Series D investment in 2021 valued the company at $2.625 billion, a 300% growth from its previous valuation in 2020.[21]

Date Funding Type Money Raised (USD) No. of Investors Lead Investor

December 2020 Series C round 50,000,000[6] 1 Sequoia Capital
July 2020 Series B round 5,000,000[33] 1 Felicis Ventures
March 2020 Series B round 23,000,000[3] 3 Craft Ventures
October 2017 Series A round 20,000,000[34] 3 Goldcrest Capital, Redpoint
