Features and specs

What each product offers, as listed by its team.

Ninja Build 5 features
LetSorted 8 features
  • Speed
    Ninja is designed for high performance, making it one of the fastest build systems available. It minimizes the time spent on tasks such as parsing, dependency resolution, and build command execution.
  • Simplicity
    Ninja’s configuration syntax is straightforward and concise, reducing the complexity involved in setting up builds and allowing for a clear overview of build rules.
  • Parallelism
    Ninja excels at handling parallel builds, leveraging multiple cores effectively to decrease overall build times.
  • Incremental Builds
    Ninja efficiently handles incremental builds by only recompiling what is necessary, which significantly speeds up iterative development processes.
  • Integration
    Ninja is often used as the backend for more complex build systems (e.g., CMake), making it a versatile tool within a larger toolchain.

Possible disadvantages

  • Limited Features
    Ninja is deliberately minimalist, lacking many of the features found in other build systems, such as built-in support for complex dependency management and custom build steps.
  • Learning Curve
    While Ninja itself has a simple syntax, the learning curve can be steep for those unfamiliar with how build systems work or for those coming from more feature-rich environments.
  • Dependency on Generators
    Ninja often requires an external generator (like CMake) to create its build files, which can add to the setup complexity and introduce dependencies on other tools.
  • Limited Scripting Capabilities
    Unlike some build systems that offer extensive scripting support (e.g., Python in SCons), Ninja's functionality is largely limited to what its syntax and predefined rules allow.
  • Less Flexibility
    Due to its minimalist nature, Ninja may not be as flexible as other build systems, potentially limiting its use in more complex or unusual build scenarios.
  • AI Tenant Screening
    Bank statement analysis, affordability scoring
  • Move-in Inspections
    Photo-based, signed by both parties
  • Compliance Tracking
    Gas, EPC, EICR expiry alerts
  • Rent Tracking

Overall verdict

  • Ninja Build is considered a strong choice for users seeking a fast, reliable, and efficient build system. Its simplicity and focus on performance make it appealing to developers working on projects where build speed is critical.

Why this product is good

  • Ninja Build is a high-performance build system designed to handle complex build processes efficiently. It is known for its minimalistic yet powerful design, which allows for faster build times compared to traditional build systems like Make. Its approach to dependency tracking and parallelism is optimized for modern build environments, making it suitable for large codebases and incremental builds.

Recommended for

    Ninja Build is recommended for developers working on large-scale projects with complex build processes, particularly in environments where build speed and efficiency are prioritized. It is especially beneficial for projects that are continuously integrated or require frequent incremental builds.

Overall verdict

  • LetSorted appears to be a UK-based property/letting management service, but I do not have verified, up-to-date information about this specific company to confirm its reputation, service quality, or customer satisfaction levels. I'd recommend independently verifying through official reviews before forming a judgment.

Why this product is good

  • Unable to confirm specific service features without verified current data
  • Cannot validate customer reviews or ratings from reliable sources
  • No access to real-time company registration or regulatory compliance information
  • Recommend checking Trustpilot, Google Reviews, or Companies House for verified details

Recommended for

  • Users should conduct independent research before relying on this assessment
  • Check official regulatory bodies like the Property Ombudsman or ARLA Propertymark for accreditation
  • Verify through direct customer testimonials and third-party review platforms

Questions & Answers

As answered by people managing Ninja Build and LetSorted.

What makes your product unique?

LetSorted's answer:

LetSorted is the only property management tool built specifically for UK self-managing landlords that automatically builds a court-ready evidence trail as you manage. Every inspection is signed by both parties, every maintenance request is timestamped, every rent payment is logged — so if a tenancy goes wrong, your evidence is already there.

Why should a person choose your product over its competitors?

LetSorted's answer:

Most UK landlord software focuses on accounting and rent tracking. LetSorted covers the full tenancy lifecycle — from AI-powered tenant screening to move-in inspections, periodic checks, maintenance logs, and a one-click Dispute Evidence Pack. It's also the only tool built around the Renters' Rights Act 2025, with RRA-compliant contracts and Section 8 evidence support built in.

How would you describe the primary audience of your product?

LetSorted's answer:

UK self-managing landlords with 1–5 properties who currently juggle spreadsheets, folders, and WhatsApp. They don't want to hire a letting agent, but they do want to stay compliant and protected — especially after Section 21 abolition.

What's the story behind your product?

LetSorted's answer:

The founder moved to the UK in 2022 and spent two weeks navigating paper forms and photocopied contracts just to rent a house. Three years later, researching buy-to-let investment, he couldn't find software that would protect a small landlord under the new Renters' Rights Act. So he built it — first for himself, then for everyone.

Which are the primary technologies used for building your product?

LetSorted's answer:

Next.js, TypeScript, PostgreSQL (Supabase), Prisma, Stripe, Resend, Claude AI (Anthropic), pdf-lib, Tailwind CSS. Hosted on Vercel with EU-based data storage.

Who are some of the biggest customers of your product?

LetSorted's answer:

Early stage, currently onboarding first users via Product Hunt launch.
