Hands-free development has transformed my workflow and now powers full-scale payment projects

As a coder, the hands-free CLI tool, particularly Anthropic Claude Platform, is invaluable. Its ability to process extensive tasks with conversation-style simplicity is unparalleled. For instance, completing complex software projects incredibly fast, potentially in mere days, showcases its power. It empowers individuals who may not have large development teams to achieve substantial outcomes independently. Anthropic Claude Platform can automate many tasks simultaneously, making it a standout feature. Even in an outage or while multitasking, I utilize Anthropic Claude Platform. With just a few commands, it can continue its processes, interact with expansive databases, and manage diverse applications without constant oversight. This capacity to function seamlessly in high-demand environments is a core strength of the platform. My experience shows that credible teams can mirror full-scale innovative solutions using Anthropic Claude Platform, such as a complete payment processing system within a day. Furthermore, I sincerely appreciate the adaptability to integrate with various systems. Different tasks necessitate specific AI solutions, and Anthropic Claude Platform, with its integration, can circulate tasks across numerous platforms. The process is smooth, allowing for prompt execution of large-scale resolutions, such as Cloud Opus 4.8.

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

"It lets a very small team ship capabilities that would normally need a much larger one."

"We have seen a return on investment with Anthropic Claude Platform, observing a 40 to 50% improvement in analyst productivity and a report preparation time reduction of nearly 70%, significantly speeding up our security investigations."

"Using Anthropic Claude Platform has changed the way I interact with my clients, and it has deepened the relationship."

"Simply put, it has become an indispensable tool for me and those around me."

"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."

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

"Using OpenLegacy, the exposure of services is far easier and quicker. In many cases, exposure of services requires just a few clicks and takes only minutes. In very complex cases, it still only takes half a day. Without OpenLegacy, it would take us several months to create the same services."

"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."

"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."

More OpenLegacy pros

Cons

"More predictable rate-limit/quota headroom for batch and high-throughput workloads, and tighter native batch-inference ergonomics would help."

"I have not noticed any issues with the AWS integration, but Anthropic themselves are difficult to deal with. They overcharged me by $1900 last month, and I am trying to get my money back while they keep sending me an AI support tool, which is a disaster."

"Sometimes I regret that Anthropic Claude Platform does not quite match up to other services such as ChatGPT 5 regarding design capabilities."

"Debugging and logging for programmers could be better."

"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 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."

"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."

"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."

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