SimplCommerce

SimplCommerce is an open-source, modular e-commerce platform built on .NET Core and ASP.NET Core. It runs cross-platform (Windows, Linux, macOS) and supports multiple databases (SQL Server, PostgreSQL). The project provides a foundation for building online stores with a pluggable architecture and admin dashboard.

What SimplCommerce is

A modulith e-commerce system written in C# using ASP.NET Core, Entity Framework Core, and ASP.NET Identity for auth. Frontend is Angular 1.6.3; domain events are managed via MediatR 7.0.0. Targets .NET 8 and supports SQL Server or PostgreSQL backends with a REST API layer.

Quickstart

Best use cases

Mid-scale B2C e-commerce platforms

Suitable for SMBs and startups building branded online storefronts where modular architecture allows incremental feature addition (product catalog, shopping cart, order management, admin interface).

Internal or custom e-commerce solutions

Organizations needing a .NET-based e-commerce backbone they can fork, customize, and deploy on-premise or in private cloud without vendor lock-in.

Learning reference for modular .NET architectures

Developers studying how to structure large .NET applications using modulith patterns, domain-driven design, and separation of concerns in a real product context.

Implementation considerations

  • Requires .NET 8 SDK, Visual Studio 2022 (or CLI tooling on Linux/Mac), and SQL Server or PostgreSQL. Local dev setup documented but assumes familiarity with .NET tooling.
  • Database schema initialization via Entity Framework Core migrations; connection strings must be configured before first run. No built-in container orchestration or Kubernetes manifests provided.
  • Admin credentials are hardcoded in demo ([email protected] / 1qazZAQ!). Change these immediately in production; no guidance on secrets management in the README.
  • Angular 1.6.3 is a single-page application; modern CI/CD and frontend build pipelines (npm, webpack) are assumed but not detailed in the core setup guide.
  • Modulith architecture requires understanding of .NET dependency injection and module boundaries; team must be comfortable with ASP.NET Core conventions.

When to avoid it — and what to weigh

  • High-scale enterprise deployments requiring SLA guarantees — No evidence of commercial support, SLA commitments, or 24/7 incident response. Community-driven; escalation paths unclear.
  • Strict Angular 2+ or React frontend requirements — Frontend uses Angular 1.6.3 (EOL in 2021). Upgrading the UI layer would require significant effort.
  • Complex multi-tenant SaaS platforms — Architecture is monolithic (modulith, not microservices). Tenant isolation, billing engines, and advanced SaaS features are absent or minimal.
  • Zero tolerance for technical debt or dependency updates — Last commit was June 2026 (recent), but latest release is listed as 'none'. Unclear versioning and release cadence; MediatR 7.0.0 is outdated (current is v12+).

License & commercial use

SimplCommerce is licensed under Apache License 2.0 (Apache-2.0), a permissive, OSI-approved open-source license.

Apache 2.0 permits commercial use, modification, and redistribution, provided a copy of the license and a notice of changes are included with the software. No patent protection is granted by the licensor. No commercial support contract, warranty, or liability indemnification is stated. Commercial deployment should include legal review of the license terms and assessment of third-party dependency licenses (e.g., MediatR, Entity Framework Core).

Security considerations

No security audit or penetration test results disclosed. Angular 1.6.3 is end-of-life; known vulnerabilities in older versions. ASP.NET Core and Entity Framework Core receive updates from Microsoft, but dependency chain (MediatR 7.0.0) is outdated. Hardcoded demo credentials in README; production deployments must enforce strong password policies, HTTPS, input validation, and OWASP best practices. No mention of rate limiting, API auth, or CORS policy guidance.

Alternatives to consider

WooCommerce (WordPress)

Mature, widely-hosted PHP e-commerce with extensive plugin ecosystem. Lower technical barrier; ideal for non-technical founders. Trade-off: less control, vendor-dependent themes.

Medusa.js (Node.js/TypeScript)

Modern, headless e-commerce API. Actively maintained, strong TS/JS tooling, and composable architecture. Better fit for teams invested in JavaScript/Node stacks.

Shopware (PHP)

Enterprise-grade e-commerce platform with strong EU support, modular plugins, and multi-channel capabilities. Higher complexity but more SaaS-like features than SimplCommerce.

SimplCommerce FAQ

Can I use SimplCommerce in production?
Yes, the Apache 2.0 license permits production use. However, ensure thorough security review, testing, and a plan for ongoing maintenance and dependency updates. No commercial support is formally offered.
Is the frontend (Angular 1.6.3) a blocker?
Depends on your team's skills. If you require modern Angular, React, or Vue, you would need to rebuild the UI—a significant undertaking. The backend APIs can be reused.
How is this different from a microservices architecture?
SimplCommerce is a modulith—a single deployment unit with logical module boundaries, not independent services. Scaling, deployment, and debugging are simpler, but there is less flexibility for autonomous team ownership.
What databases are supported?
SQL Server (via Entity Framework Core on Windows) and PostgreSQL (via EF Core on Linux/Mac). Entity Framework Core supports other databases (MySQL, SQLite); confirm support in the documentation.
