List of Rust Customers
Since 2010, our global team of researchers has been studying Rust customers around the world, aggregating massive amounts of data points that form the basis of our forecast assumptions and perhaps the rise and fall of certain vendors and their products on a quarterly basis.
Each quarter our research team identifies companies that have purchased Rust for Apps Development from public (Press Releases, Customer References, Testimonials, Case Studies and Success Stories) and proprietary sources, including the customer size, industry, location, implementation status, partner involvement, LOB Key Stakeholders and related IT decision-makers contact details.
Companies using Rust for Apps Development include: Amazon Web Services, a United States based Communications organisation with 130000 employees and revenues of $107.60 billion, Dropbox, a United States based Communications organisation with 1800 employees and revenues of $2.55 billion, Cloudflare, a United States based Professional Services organisation with 4263 employees and revenues of $1.67 billion, Modal, a United States based Professional Services organisation with 50 employees and revenues of $6.0 million and many others.
Contact us if you need a completed and verified list of companies using Rust, including the breakdown by industry (21 Verticals), Geography (Region, Country, State, City), Company Size (Revenue, Employees, Asset) and related IT Decision Makers, Key Stakeholders, business and technology executives responsible for the software purchases.
The Rust customer wins are being incorporated in our Enterprise Applications Buyer Insight and Technographics Customer Database which has over 100 data fields that detail company usage of software systems and their digital transformation initiatives.

Amazon Web Services | Communications | 130000 | $107.6B | United States | Rust | Rust | Apps Development | 2018 | n/a |
In 2018 Amazon Web Services developed Firecracker, a microVM monitor written in Rust, to provide fast, secure lightweight virtualization underpinning serverless services such as AWS Lambda and AWS Fargate. Rust was used as the implementation language within the Apps Development category to deliver system-level application code that emphasizes memory safety and performance for infrastructure workloads.
The implementation centers on a compact virtual machine monitor designed to minimize runtime footprint while improving isolation and startup latency for ephemeral compute instances. Functional capabilities implemented include lightweight virtualization for short lived workloads, process isolation suitable for multi tenant serverless execution, and a small trusted computing base to reduce attack surface for compute hosts.
Firecracker was integrated into AWS Lambda and AWS Fargate and entered production use shortly after 2018, representing an infrastructure level adoption of Rust to support serverless compute services. Operational scope covered serverless compute platforms rather than end user applications, positioning Rust as the core systems language for this compute layer and influencing build, testing, and release pipelines for those services.
Governance and operational practices shifted toward systems programming disciplines aligned with Rust usage, including stricter compile time checks and language level memory safety expectations for engineers maintaining Firecracker. The stated outcomes in this implementation were improved isolation and reduced startup latency for serverless compute, aligning Amazon Web Services Rust Apps Development work with hardened, low latency virtualization at the infrastructure and compute layer.

Cloudflare | Professional Services | 4263 | $1.7B | United States | Rust | Rust | Apps Development | 2019 | n/a |
In 2019, Cloudflare implemented Rust as part of its Apps Development work to build core networking and agent components. Cloudflare built BoringTun, a userspace WireGuard implementation, in Rust to improve performance, security, and cross-platform support for its WARP and Cloudflare One agent and edge services in the United States.
The Rust-based implementation is embedded into Cloudflare’s edge and networking stack, where it serves as a native userspace VPN and wire protocol module. BoringTun and related Rust components provide userspace WireGuard functionality, cryptographic primitives, and asynchronous networking capabilities consistent with Apps Development patterns for native performance and safety.
Integrations explicitly include the WARP client and the Cloudflare One agent, and the Rust components are used across Cloudflare edge services to provide secure tunneling and agent-side networking. The deployment structure is focused on edge delivery and agent runtime integration, with cross-platform builds to support multiple operating systems and edge node environments.
Governance and rollout were driven by Cloudflare engineering teams, with the changes announced and deployed around 2019 and documented in public engineering blog posts. Module usage and implementation details are inferred from those posts, and the implementation narrative centers on Cloudflare Rust Apps Development for networking and agent business functions.

Dropbox | Communications | 1800 | $2.5B | United States | Rust | Rust | Apps Development | 2015 | n/a |
In 2015 Dropbox implemented Rust across infrastructure and client components as part of its Apps Development efforts, embedding the Rust application language into core storage and desktop synchronization subsystems. Dropbox implemented Rust to support development of performant, memory-efficient modules while retaining existing storage architecture components such as Magic Pocket and the desktop sync engine.
Implementation scope covered both backend and client-side code, with Rust used in Magic Pocket exabyte scale storage components and the desktop sync engine, and the engineering team building a custom Rust library for the Capture client feature. The Rust application was adopted for client libraries and modules that required reduced memory footprint and improved reliability in the file storage platform, outcomes explicitly stated by Dropbox engineering.
Operational coverage is United States focused within Dropbox engineering, with engineering posts indicating module usage across storage and client libraries rather than a single component adoption. The integration pattern centers on embedding Rust into existing storage pipelines and client sync processes, and using Rust libraries for feature development in Capture and other client capabilities.
Governance and rollout followed an engineering led expansion, with Rust pushed to production for client components by 2021 and internal libraries standardized to support cross component reuse. The narrative reflects Dropbox engineering decisions to centralize Rust development for both infrastructure and client features, aligning the Rust application with Apps Development practices for system reliability and memory efficiency.
