Centralized API documentation has improved collaboration and reduces onboarding time
Overall, I have had a positive experience with ReadMe, but there are a few areas where I think it could improve. One is customization. While it is easy to create clean documentation, making deeper UI or layout customizations can be somewhat limiting without additional effort. Having more built-in customization options would help teams tailor the developer portal to their branding and documentation needs. I would also like to see more advanced analytics. It would be useful to have richer insights into which APIs are viewed most frequently, where developers spend the most time, and which document pages generate the most support requests. Those metrics could help us continuously improve our documentation. Another improvement would be the tighter integration with Git-based development workflows. While synchronizing documentation works well, making documentation updates, previews, and reviews even more seamless as part of the pull request process would improve the developer experience. All of these are not major issues. They are enhancements that would make an already solid platform even better. Overall, ReadMe has worked well for our API documentation needs. An additional improvement I would like to see is better support for documentation versioning and change tracking. In enterprise applications, APIs evolve over time, and having more intuitive tools to compare versions and clearly highlight changes would make it easier for both internal teams and external consumers to adopt new API versions. I would also appreciate more built-in collaboration features, such as richer review workflows or commenting capabilities for documentation changes before they are published. That would make it easier for developers, QA teams, and technical writers to review documentation together and keep it accurate. Other than those enhancements, I think ReadMe is an easy-to-use platform that has met our API documentation needs. I do not have any major concerns beyond the improvements I already mentioned.

Automated infrastructure deployment has reduced our backend release time from days to hours
I found an issue with features that was difficult for me when we needed to retrieve some tags or IDs of a resource that we deployed using Upbound Crossplane, for example, the RDS. We encountered a problem where we needed to use the ID of the RDS in another document that we have, making it difficult to return this information using Upbound Crossplane deployment. I believe Upbound Crossplane could be improved by possibly having a feature that can return tags, IDs, or resources that were deployed inside AWS, such as needing to return the ID of the VPC that we create when using Upbound Crossplane. I think the current state of Upbound Crossplane is already good enough.

Pros

"Overall, if your organization wants to improve the developer experience, reduce repetitive support questions, and provide a centralized and professional API portal, I think ReadMe is a strong choice."
"With ReadMe serving as a clear, self-service developer portal, our partners can now complete their integration in a fraction of the time, which has accelerated project delivery timelines, improved our partner satisfaction, and optimized engineering promises."
"Before choosing Upbound Crossplane, I evaluated various options, but I only found Upbound Crossplane to be the best choice."
"We went from having a 28-member troubleshooting team down to four to five members of the platform engineering team."
"When I provisioned PostgreSQL and S3 buckets through Crossplane, I noticed improvements in deployment speed, reliability, and team collaboration."
"The time required to complete an environment setup was reduced from about one or two weeks to forty to fifty minutes."
"Upbound Crossplane impacts my organization positively because, from our perspective, we need to rely on fewer resources."
"Upbound Crossplane has impacted our organization positively as it has been a transformative experience because the main thing about transformation is how we were able to make our lives easier as engineers."
"Upbound Crossplane has positively impacted our organization by allowing us to reduce our deployment time from three days to three hours for the entire back-end and entire infrastructure."
"The best features Upbound Crossplane offers are infrastructure as Kubernetes APIs and self-service infrastructure, where developers can provision resources without cloud credentials, and its strong multi-cloud support that makes it useful in managing AWS, Azure, and GCP from a single control plane with valuable GitOps integration."
 

Cons

"We could probably have more advanced analytics, multi-domain support, or something similar, and advanced access controls."
"One is customization. While it is easy to create clean documentation, making deeper UI or layout customizations can be somewhat limiting without additional effort."
"However, one area of improvement is the learning curve, as Upbound Crossplane concepts such as providers, compositions, and claims can be difficult for beginners."
"Regarding Upbound Crossplane, I see room for enhancement in synchronizing the state file of Crossplane with Terraform, as 90% of organizations have generally implemented Terraform and have their own specific, environment-specific Terraform state files."
"One area where Upbound Crossplane can be improved is with API rate limiting."
"Regarding Upbound Crossplane's capabilities, I feel the governance and security is something which is lacking."
"I found an issue with features that was difficult for me when we needed to retrieve some tags or IDs of a resource that we deployed using Upbound Crossplane, for example, the RDS."
"Upbound Crossplane was not stable in my experience."
"Upbound Crossplane can be improved if they can add more AI agentic workflows."
"The documentation needs to be updated regarding the needed improvements for Upbound Crossplane. There is very little documentation online, and there are no tutorials for Upbound Crossplane."
