Open Source Software Companies To Watch

Open source continues to be an important part of IT. Red Hat’s recent “state of enterprise open source” report found that 82 percent of surveyed IT leaders are more likely to work with vendors who contribute to the community.

And open source tools continue to take share from proprietary ones, with 80 percent of surveyed IT leaders saying they expect to increase their use of enterprise open source software for emerging technologies. Almost 90 percent of respondents said they see enterprise open source as more secure or equal to proprietary software.

Along with this list, CRN has also found companies to watch in tech industries including cloud, development operations (DevOps), cybersecurity, secure access service edger (SASE) and edge computing.

Read on for whom we consider the hottest open source software companies to watch in 2023.

Microsoft And GitHub

GitHub is one of the best known hosts of open source software development projects, and parent company Microsoft is a major contributor on the platform.

In the 2022 Octoverse report by GitHub – based in San Francisco and led by CEO Thomas Dohmke – Microsoft was responsible for the project with the highest contributor count, with 19,600 contributors on Visual Studio Code code editor program.

Redmond, Wash.-based Microsoft also ranked high for 12,200 contributors on its open source documentation of Azure; 7,500 contributors for the vendor’s PowerToys Windows system utilities; 4,800 contributors for issues on Windows Subsystem for Linux; and 4,500 contributors for Microsoft’s TypeScript superset of JavaScript.

PowerToys was No. 2 for the highest volume of contributor growth with 2,240 contributors. Microsoft’s .Net multi-platform application user interface (MAUI) framework for device application building ranked No. 4 with 1,770 contributors and Playwright framework for web testing and automation ranked No. 5 with 1,690 contributors.

On Microsoft’s latest quarterly earnings, CEO Satya Nadella revealed that GitHub reached 100 million developer users and called the GitHub Copilot paired programming AI tool “ the first at-scale” large language model (LLM) AI product on the market with a million users to date.

IBM And Red Hat

IBM subsidiary Red Hat bills itself as the largest open source company in the world, with popular open source products including Red Hat Enterprise Linux (RHEL), the OpenShift enterprise-grade application platform and the Ansible open source automation project.

The Raleigh, N.C.-based vendor, led by CEO Matt Hicks, ranked No. 7 from GitHub last year for highest growth of new contributors with 1,610 contributors on its Keycloak identity and access management tool.

This year, the vendor has already made news about expanding access to its open source tools, including expanded partnerships with SAP, Oracle and Google.

Arvind Krishna – CEO of Red Hat parent company Armonk, N.Y.-based IBM – also continues to champion the open source vendor as a growth driver, shouting Red Hat out on IBM’s latest quarterly earnings call.


Google launched one of the first open source program offices in the industry back in 2004, and it’s continued to support a variety of projects in the space since then – including investing about $7 million in direct funding to open source communities.

At 12,400, Google’s Flutter open source framework for multi-platform applications had the third highest number of contributors for a project on GitHub – after GitHub parent Microsoft. Its TensorFlow machine learning (ML) and artificial intelligence (AI) software library ranked No. 10 with 4,400 contributors.

In October, Sigstore – which started as an open source collaboration between Red Hat and Google – launched general availability of the free, community-operated certificate authority and transparency log services, plus version one releases of the Fulcio and Rekor projects.

That same month, Google open sourced multiple components of its KataOS secure operating system and partnered with Antmicro on its Renode simulator and related frameworks.

In September, Mountain View, Calif.-based Google made its TensorStore C++ and Python library open source, according to a tweet from CEO Sundar Pichai.


Vercel is perhaps best known for maintaining the Next.js web development framework, which ranked No. 6 on GitHub last year for top open source projects with 5,900 contributors.

Based in San Francisco and led by CEO Guillermo Rauch – who founded the company in 2015 – Vercel made news in October with the acquisition of Splitbee to bring more analytics capabilities to its offerings.

Other major product updates from Vercel include enhancing preview deployments with the ability to comment on work in progress, added privacy controls across all Vercel plans and making edge functions generally available to give developers more flexibility regardless of user location and network speed.

Vercel also has a partner program for consultants.


Cybersecurity vendor Snyk ended 2022 with an eye-catching $196.5 million Series G funding round, but what also makes headlines for the company is its dedication to open source software.

Boston-based Snyk, led by CEO Peter McKay, is a supported provider of the Bomber open source software bill of materials (SBOM) vulnerability scanner, for example.

In January, Snyk announced new integrations between its own open source offering and ServiceNow Application Vulnerability Response.

Image, text, columns and other built-in components of Builder are open source, according to the startup.

The 2022 Runa Open Source Startup (ROSS) Index by venture capital firm Runa Capital ranked Builder the No. 1 overall fastest-growing open-source startup last year.

The ranking is based on the annualized growth rate (AGR) of GitHub stars at the startups’ repositories. Builder scored 14,134 stars for a stars AGR rate of 968 percent. It also received 623 forks for a forks AGR of 1,528 percent.

Builder.io has a partner program aimed at ecommerce agencies and consulting firms.


MindsDB describes its mission as democratizing machine learning (ML) by giving users popular frameworks to bring ML to applications for new capabilities and to save on costs.

MindsDB is based in Berkeley, Calif., and led by CEO Jorge Torres, who co-founded the startup in 2017.

In January, Gartner named MindsDB in its “Cool Vendors in Data-Centric AI” report.

Since then, Observable has deepened integrations with the likes of MongoDB, Microsoft SQL Server, Oracle and Databricks. The company also added more capabilities around sorting and filtering, notebook version pausing, data tables and more.

Before she co-founded Observable, Meckfessel was a vice president of engineering at Google, where she worked for more than 14 years, according to her LinkedIn account.

Grafana Labs

Grafana Labs offers an open observability platform for monitoring and analyzing databases.

The New York-based company, led by CEO Raj Dutt, offers a variety of open source projects including Grafana Loki for logging, Grafana Tempo for traces and Grafana Mimir for metrics.

Grafana passed more than 1 million active users in 2022. In April, Grafana secured a $240 million Series D round of funding.

In 2023 so far, Grafana has updated the design of its technical documentation, released the second iteration of Tempo and made various improvements to Grafana Agent.

Strata Identity

Strata Identity started the year with a $26 million Series B round of funding to scale sales, marketing, customer success and go-to-market activities for its distributed multi-cloud identity orchestration tools.

New investor Telstra Ventures participated in the round along with existing investors Menlo Ventures and ForgePoint Capital.

The Boulder, Colo.-based startup’s founders – including CEO Eric Olden – co-created the Security Assertion Markup Language (SAML) open standard for authentication and authorization and delivered the first open-source identity products.

The startup’s leaders aren’t resting on their laurels, though. In May, Strata made the Identity Query Language (IDQL) open source project available for users to apply consistent access policy across any applications on any cloud. IDQL works with Hexa, an open source reference implementation.

Strata has a partner program aimed at resellers, managed service providers and other partner types.
