Room For Improvement

Boomi AtomSphere Flow needs user-friendliness, stability, AI enhancements, better support, and flexibility for complex integrations and large datasets.
OutSystems requires improvements in pricing, support, AI integration, testing, performance, documentation, containerization, and version control to satisfy users.
Boomi could improve its customer support by providing clearer communication channels, enhancing responsiveness, and offering more proactive support resources like newsletters and webinars.
associate director at Nagarro
It lacks features like the ESQL scripting language found in IBM's, which makes integration transformations easy.
Integration Architect at a consultancy with 1-10 employees
You have to design your architecture in a very magnificent and decent way so that how you process your data so that load can be easily balanced.
Sr. Project Delivery Lead | Sr. Technical Lead at a manufacturing company with 5,001-10,000 employees
OutSystems does support tools to help categorize components across different layers, but enhancing features related to architecture would be beneficial for accommodating new changes more easily in our existing applications.
Software Developer Advisor at NTT DATA Services
In the future with OutSystems, improvements could be made on the costing side rather than the feature side.

Setup Cost

Boomi AtomSphere Flow's pricing is seen as reasonable, especially for small-scale operations, with ratings averaging 6.5-7/10.
OutSystems is seen as expensive, especially for smaller organizations, but some find its robust features justify the cost.
The pricing is considered a bit expensive yet not excessively so, particularly when compared to similar solutions like MuleSoft.

The pricing is good for a small-scale company like ours, and the licensing cost is reasonable.
Integration Architect at a consultancy with 1-10 employees
Subsequent users can be added at an additional cost per user; exact pricing details can be found on the OutSystems site.

Enhances application integration with scalability, reliability, and security
Boomi AtomSphere Flow facilitates data availability across different departments, allowing our clients to generate diverse analytical reports that aid senior management in making informed decisions. The integration layer ensures data security, which is supported by Boomi's EDA and API management capabilities. The solution unites all these functions, preventing the need for separate products for specific operations.
Aditya Bhatt - PeerSpot reviewer
Sr. Project Delivery Lead | Sr. Technical Lead at a manufacturing company with 5,001-10,000 employees
Rapid delivery has transformed complex enterprise apps and supports faster cross-domain projects
Every platform or low-code platform tool is quite good in its own area, but there is always space to groom or enhance or improve. The same is with OutSystems as well. A couple of things from the integration point of view can be enhanced. If your application or the enterprise organization is tackling a huge data application where you have bulk amounts of data, it becomes a challenge for all the technologies and the same with OutSystems. You have to design your architecture in a very magnificent and decent way so that how you process your data so that load can be easily balanced. Data handling and huge data handling is a kind of challenge you may need to face. Then we have some vendor lock-in. If you are trying to migrate your application from OutSystems, then you probably get into this vendor lock-in system. Some organization may face challenges if some organization is on a small scale size. The small scale businesses may find OutSystems costly because of its high cost and pricing due to the licensing cost. Apart from that, OutSystems really plays well, and it needs a learning curve. If a traditional application or programming is there which your developers are skilled into and they are directly deployed into OutSystems, it may take some significant amount of time for them to get comfortable with OutSystems. There is a learning curve. OutSystems community is already in place, but it can more be enhanced regarding some aspects. They did organize lots of bootcamps and other user groups as well, but those can also be improved from the documentation point of view and having some integration guidebook as well. A couple of things which can be improved into OutSystems include the licensing cost, the vendor lock-in side, the learning curve, couple of integration aspects and customizations.
