curl (and libcurl)

Business Profile

Core Value Proposition

curl provides data transfers across 28 URL schemes and runs on over 100 operating systems and almost 30 CPU architectures.

Target Customer

Software developers and organizations requiring cross-platform, multi-protocol data transfer capabilities; contributors and maintainers of open source software.

Key Differentiator

Mature, open-source transfer project with broad platform and protocol coverage, a large contributor base, and a structured security and release process (HackerOne involvement, CVE management, and formal release notes).

Implementation Timeline

Not specified in content; however, the project emphasizes an eight-week release cycle for security advisories and regular, documented release processes.

Pain Points

1Need for reliable data transfers across many protocols across diverse platforms and architectures.
2Maintaining cross-platform compatibility and broad OS/architecture support in a single, well-maintained project.
3Transparent handling of security issues and vulnerability reporting with formal advisories and coordinated releases.

Key Features

1Supports data transfers across 28 URL schemes.
2Runs on over 100 operating systems and almost 30 CPU architectures.
3Open-source project with a large number of contributors and a documented release process.
4Structured release notes workflow, including scripts for release tarball creation and verification.
5Formal security workflow with a vulnerability reporting program (HackerOne), CVE management, and security advisories.

Target Customer Industries

Client Results

1Broad adoption across platforms with a mature, actively maintained codebase and frequent bug fixes (e.g., 12,500 documented bug fixes across releases and 1,400+ contributors).
2Transparent security governance including vulnerability reports, CVEs, and public advisories.
3Structured release process producing reproducible release tarballs and detailed release notes.

Competitive Advantages

1Extensive cross-platform and multi-protocol support in a single project.
2Large, active open-source community and long history of development and maintenance.
3Rigorous security disclosure and advisory workflow (HackerOne, CVE authority) with documented procedures.
4Transparent, automated or scripted release processes (release notes, tarball verification).
5Proven impact and reach (widely used, with many contributors and numerous bug fixes).

Key Benefits
