The ability to configure rules to check for consistency has helped

Apiary provides a free tier of the platform which allows a small group of developers to collaborate easily on the design of open source APIs. In addition to this, it provides mock endpoints allowing people to experiment with the API without depending or having to stand up a real backend. With our clients, using Apiary allows us to very quickly pull together an API definition (particularly when using API Blueprint). The whole API design process for the simpler use cases can be done in a relatively short workshop which makes it a lot easier to agree, publish, version-manage an API definition with suitable documentation. This can then be evolved and enhanced (particularly in the documentation aspects). With the ability to support Swagger (Open API v2 and introducing/ed support for v3) and API Blueprint makes it a very versatile tool.

The biggest advantage is how simple the technology was.

I'd like to see OpenLegacy develop its low-code/no-code (LCNC) solutions. They've expanded somewhat their horizons for integration beyond mainframe CICS, which is their sweet spot. They have some tooling in that area, but it's not as good as it needs to be. OpenLegacy handles the bread-and-butter TP monitoring stuff, but I am working for one of the six banks in the United States still using the Hogan mainframe, which has a slightly proprietary mechanism. But OpenLegacy currently doesn't have a connector for Hogan. So it would help if they could build one. That would appeal to financial institutions that still use Hogan, like US Bank, Wells Fargo, KeyBank, and Vanguard.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"I do like the overall performance of the solution."

"Git integration"

"In two years, there was one time the service was down for an hour or so."

"Vey high - very easy API design with no setup effort"

"Quick and easy way to share a new API design with teams."

"The feature I find most valuable is that it offers authentication and allows us to develop communication points."

"This solution has allowed us to standardize API definitions and bring consistency into our shared components, reducing the effort and cost of using functionality across domains within the organization, with Apiary being crucial to our good API strategy."

"I find the generation of mock services very useful, especially when demonstrating for new consumers."

"OpenLegacy opens the door to connect modern web products to our old legacy system."

"The product has helped our business by allowing us to become more efficient in data handling."

"OpenLegacy produces a war file which includes everything you need to deploy a Tomcat server."

"The biggest advantage of OpenLegacy was how simple the technology was, and we were able to build out the OpenLegacy parts very quickly, putting together a couple hundred APIs in six months."

"Using mainframe programs (not screens), the OpenLegacy services do not require any changes by the mainframe programmers, thus reducing development cycles."

"Without OpenLegacy, it would take us several months to create the same services."

"It is possible to connect a service to a mainframe program or back transaction in a matter of minutes or hours at the most."

"OpenLegacy provides a way to go from the outside world to the legacy mainframe, to move the old standard application to a REST API application. New digital services can be created in a few clicks and this can be done easily by COBOL programmers."

More OpenLegacy pros

Cons

"The Oracle release cycle is very bad because the patches only update once a year."

"Better Swagger support."

"I don't think this solution is very stable so we try to manage stability from our side."

"Validation messages could be a bit clearer."

"I would like an integrated option to download a Swagger version of the definition."

"Swagger (OpenAPI Specification) and Blueprint Support"

"Customer support for the product is slow and not very good. It makes using the product difficult if you need help quickly."

"The pricing of the solution could be more flexible and allow for once-off payment versus annual licensing. This would be more appealing to companies in Latin America."

"We would also be more than happy if the product had the option to work in the opposite direction – the ability to consume REST/SOW services in the outer world from the mainframe."

"I'd like to see OpenLegacy develop its low-code/no-code (LCNC) solutions. They've expanded somewhat their horizons for integration beyond mainframe CICS, which is their sweet spot. They have some tooling in that area, but it's not as good as it needs to be."

"Debugging and logging for programmers could be better."

"I would like to see SSL out-of-the-box. OpenLegacy certainly does SSL, but it was not the default for our use case. We are currently working with OpenLegacy to cross the SSL bridge and suspect that most users will want to do the same."

Pricing and Cost Advice

"It is easy to get started with personal (free) accounts, but a subscription is required for additional features."

"There is a free subscription option to start and try the service."

"The pricing of the solution could be more flexible and allow for once-off payment versus annual licensing. This would be more appealing to companies in Latin America."
