ABP Framework is a popular choice for building enterprise‑grade .NET applications, but it is not the only option for teams that want faster delivery, different architecture choices, or simpler tooling. This guide covers leading ABP Framework alternatives, when to use them, and how they compare across features, learning curve, and pricing.
What developers usually want from an ABP alternative
Most teams looking beyond ABP are trying to solve at least one of these problems: avoiding steep learning curves, reducing boilerplate, or finding a better fit for SaaS and multi‑tenant apps. Typical must‑haves include multi‑tenancy, authentication and authorization, modular architecture, cloud‑ready deployment, and good documentation.
- Enterprise features: auth, roles/permissions, audit logs, localization, tenant isolation.
- SaaS‑ready foundations: subscription billing, user management, email templates, multi‑factor authentication, and strong security defaults.
- Reasonable learning curve: clear docs, familiar patterns (Clean Architecture, DDD, CQRS) and community support.
Quick overview of top ABP Framework alternatives
| Alternative | Best for use case | Core strengths | Pricing / license (high level) |
|---|---|---|---|
| Brick .NET Starter Kit | SaaS products, multi‑tenant apps, and ASP.NET Core with React/Angular front ends. | Full SaaS boilerplate with multi‑tenancy, auth, payments, email, plus modern Angular/React UI. | Commercial, per‑project |
| Clean Architecture Solution Template | Teams wanting full control and clean patterns on ASP.NET Core. | Opinionated Clean Architecture, CQRS, MediatR, testability. | Free and open source. |
| .NET Boxed Templates | API‑first and microservice‑style backends in .NET. | Performance‑oriented API templates, GraphQL support, modern best practices. | Free and open source. |
| Equinox Project | Learning DDD, CQRS, and event‑sourced architectures. | Strong DDD focus, CQRS, event sourcing demo. | Free and open source. |
| eShopOnWeb & Northwind samples | Learning real‑world patterns and reference architectures. | Microsoft‑backed examples with clean layering and tests. | Free and open source. |
| IdentityServer‑based templates | Identity‑centric applications that need standards‑based auth. | OAuth 2.0 / OpenID Connect, enterprise‑grade identity features. | Free to develop; commercial for production in many cases. |
| Other SaaS boilerplates (.NET) | Off‑the‑shelf SaaS foundations and admin panels. | Varying combinations of multi‑tenancy, UI, and DevOps scaffolding. | Mix of free and commercial. |
1. Brick .NET Starter Kit – SaaS‑focused ABP alternative
Brick is a SaaS starter kit and boilerplate that gives you a production‑ready ASP.NET Core backend plus modern Blazor, React, Angular, Vue, Razor front ends, aimed at founders and teams building multi‑tenant SaaS products and internal applications. It ships with tenant management, authentication via email (ASP.NET Identity)/social/Entra ID, multi‑factor authentication, roles and permissions, user management, email templates, isolated tenant databases, multi‑language support, recurring payments, and data encryption out of the box.
- When it fits: startups or product teams that want to skip account, tenant, and billing infrastructure and go straight to feature development; organizations migrating legacy apps into a cloud‑native SaaS setup with multi‑tenancy.
- Trade‑offs: commercial licensing, and the paid kit includes full source code plus optional implementation support from a SaaS‑focused services company. Free with MVP Development service.
2. ABP.io Community (Free version)
ABP Framework is the official successor to ASP.NET Boilerplate, offering modular architecture, microservice support, and a rich ecosystem of modules and tooling. It is a strong option for teams that are already invested in ABP and willing to adopt its patterns thoroughly.
- Why look for alternatives: some teams find the learning curve steep, the stack opinionated, and the commercial licensing for advanced modules or themes more than they need for smaller SaaS projects.
- When to keep ABP: if your team already knows the framework, relies on its module ecosystem, or needs its microservice story and official migration guides from older ASP.NET Boilerplate projects.
3. Clean Architecture Solution Template
The Clean Architecture Solution Template (popularized by Jason Taylor) is a well‑structured ASP.NET Core template that emphasizes separation of concerns, CQRS, and testability. It gives you folders, layers, and patterns rather than a full SaaS product skeleton.
- Strengths: fully open source, clean layering, good for teams that want to understand and own every part of the stack without a vendor‑specific framework.
- Limitations: no multi‑tenancy, billing, or SaaS features pre‑built, so teams must implement account, tenant, and operational capabilities themselves.
4. .NET Boxed Templates
.NET Boxed Templates focus on high‑quality API and microservice templates, including REST and GraphQL APIs with modern .NET practices and performance tuning. They are ideal if your priority is backend API architecture rather than a full SaaS application layer.
- Strengths: excellent defaults for APIs, strong adherence to modern .NET guidance, and active community usage.
- Limitations: fewer out‑of‑the‑box enterprise SaaS features, so you still need to design multi‑tenancy, UI, and billing flows separately.
5. Educational and reference projects (Equinox, eShopOnWeb, Northwind)
Equinox, eShopOnWeb, and the Northwind Clean Architecture sample are widely used to learn DDD, CQRS, and layered architectures in .NET. They are maintained examples that demonstrate patterns rather than drop‑in SaaS solutions.
- When they help: upskilling your team on architecture patterns before standardizing your own boilerplate, or using them as internal templates for small internal tools.
- Where they fall short: not feature‑complete for multi‑tenant SaaS, payments, or complex user management, so they typically require significant customization for production products.
6. IdentityServer‑based templates and other specialized stacks
For teams whose primary pain point is identity rather than full application scaffolding, IdentityServer‑centric templates provide standards‑based authentication (OAuth 2.0, OpenID Connect) and SSO support in .NET. Many .NET SaaS boilerplates and frameworks integrate these libraries under the hood for enterprise‑level security.
- Good fit: organizations that already have internal services and only need a robust identity provider to integrate them.
- Not enough alone: you still need to build tenant isolation, UI, billing, and operational tooling on top of these identity layers.
How to choose the right ABP alternative
Choosing an ABP alternative comes down to how much you want pre‑built versus how much you want to design yourself. As a rough rule of thumb, SaaS founders and teams that want to ship quickly with multi‑tenant support, authentication, payments, and a modern SPA UI typically lean toward opinionated SaaS starter kits like Brick, while platform teams with strong internal standards often prefer lighter templates like Clean Architecture or .NET Boxed and assemble their own stack.
