In this article, we'll dive into Appsmith and Retool to help you understand the benefits and drawbacks of each platform and identify the best fit for your business.

The benefits of internal tooling platforms

Most businesses have a variety of internal processes that rely on spreadsheets or email. As operational complexity increases, these processes become outdated or fall out of compliance, inhibiting teams from best serving their customers.

‍

Business build custom internal software to manage this operational complexity, enabling teams to better serve customers and successfully scale their business. However, building and maintaining these tools from scratch is expensive and time-consuming, requiring frontend, backend, and infrastructure engineering expertise.

‍

Internal tooling platforms like Appsmith, Retool, and Superblocks enable higher development velocity for organizations, protecting engineering resources and resulting in better software for operations teams. 

Internal tooling platform evaluation criteria

We've compiled the common set of decision criteria used to select a low-code internal tooling platform, based on several customer evaluations in the space: 

• Easy to use: Low-code platforms must be easy to use and intuitive to ensure adoption across users of varying technical expertise. These tools must enable developers to quickly build applications and streamline workflows
• Scalable and performant: Enterprises are building mission-critical apps, so these apps must be scalable and performant with high data volumes and intensive processing
• Extensible with code: Organizations have unique needs and the ability to implement custom logic and extend the app builder with custom code in a language of their choice is necessary for a future-proofed solution to avoid being blocked on the platform’s out-of-the-box capabilities
• Cost-effective to self-host: Mission-critical apps interact with production databases and other sensitive data, making it a requirement that data does not leave their VPC. A vendor must offer this functionality without significant additional overhead to avoid bloating the total cost of ownership
• Cutting-edge AI: Enterprises want to work with modern and innovative vendors incorporating the best technologies. AI is crucial for accelerating software development and empowering organizations to deliver quickly and efficiently
• Exceptional support: Enterprises require that bugs, issues, and feature requests are handled in a timely manner and that their requests are resolved quickly to not block any of their business activities and impede development of mission-critical apps
• Monitoring and observability: Enterprises need to monitor the software they build with low-code platforms using their observability vendors like Datadog and New Relic so they can detect errors and ensure software quality remains high
• Real-time streaming: Enterprises must provide ops teams real-time data and insights for optimal decision-making, so platforms need to support building on top of streaming platforms like Kafka, Kinesis, Confluent, and OpenAI
