Architecture and Openness

Betty Blocks

Betty Blocks distinguishes itself with an open platform architecture that avoids vendor lock-in and supports future-proof app development. Applications built on the platform can be fully exported, giving enterprises ownership of their code and flexibility to adapt as requirements evolve. This openness is particularly valuable for IT leaders who prioritize long-term adaptability and cost control. Unlike proprietary systems, Betty Blocks fosters interoperability with external systems, APIs, and emerging technologies.

OutSystems

OutSystems is built on a proprietary architecture designed to maximize control and integration within its ecosystem. Although this closed approach delivers a mature foundation for large-scale enterprise applications, it ties organizations to OutSystems’ technology stack and excludes all other company sizes besides enterprise. While robust in terms of enterprise integrations, the architecture limits long-term flexibility. Enterprises may dig themselves into a financial hole, given the costs of eventually switching platforms when OutSystems doesn’t meet their use case requirements.

Platform user experience

Betty Blocks

Betty Blocks emphasizes a simple yet flexible user experience. The platform prioritizes business user accessibility, enabling both business users and professional developers to collaborate effectively. The intuitive drag-and-drop interface and visual modeling reduce the learning curve, enabling citizen developers to make meaningful contributions without extensive training.

At the same time, IT professionals benefit from structured governance layers that keep projects compliant and secure. This dual focus ensures that applications are not only built quickly but also aligned with enterprise standards and best practices. By prioritizing usability across skill levels, Betty Blocks bridges the gap between business needs and IT oversight, encouraging innovation without sacrificing control.

OutSystems

Although OutSystems hails from Portugal, the sunny disposition of the country is not reflected in the design of the platform. The user experience is designed for professional developers who require advanced capabilities, including complex workflow modeling, integrations, and DevOps features. While citizen developers can contribute, OutSystems is more geared toward teams that are technically mature and comfortable with a steeper learning curve in exchange for flexibility.

Control and governance

Betty Blocks

Betty Blocks has consistently prioritized governance to support its longstanding commitment to the citizen developer community. This governance-first model allows citizen developers to innovate while operating safely within boundaries defined by IT. Combined with its track record for paramount governance, Betty Blocks lends itself particularly well to the latest coding trends within the contemporary technology sphere. The balance between freedom for business users and oversight for IT ensures sustainable, secure application delivery.

OutSystems

OutSystems has had a longstanding reputation for excellent compliance and governance. While necessary for enterprises and organizations in heavily regulated markets, agile and fast-scaling businesses might see these perks as a feature overkill and added extra expenses. Enterprises benefit from strong guardrails, but customization of governance frameworks can be limited. For organizations already standardized on OutSystems, this delivers predictability and compliance, although it may feel restrictive for enterprises seeking the adaptability and openness that Betty Blocks offers.

Scalability and future-proofing

Betty Blocks

Both are strong contenders for organizations aiming to innovate with low-code safely. Still, Betty Blocks is the only platform that enables teams to introduce an open platform architecture safely into their workflows. With Betty Blocks, users will continuously be able to access the underlying code of their applications. Ownership and openness provide the reassurance that even when market trends become dicey, your Betty Blocks solutions are flexible enough to rise to the challenge.

OutSystems

Building apps effectively requires more training and technical expertise compared to Betty Blocks. This can significantly slow down onboarding and increase the barrier to entry for non-developers. Technical challenges can increase overall costs, primarily if teams aim to migrate away from their current system and adopt a different development approach. Businesses below the enterprise scale will feel left out in the cold by OutSystems' rigid architecture, overpriced features, and lack of personalized support.
