I don't like that the web server crashes every day, every 24 hours. The pricing could be improved because scaling the database becomes costly. The Docker features are not great. You cannot use any Docker image. They removed many free plans. They don't have free usage anymore.

For one of our projects, I faced some slug issues because the slug size was restricted to 400 MBS, and my application slug size exceeded that limit. So, I had to make many changes in the environment and infrastructure to fix that issue. Heroku should increase its slug size limits.

I improved the application performance by monitoring and adjusting the cleaner configuration to help set better lightweight limits on containers that run the app instances.

Heroku had an authentication problem a few months ago, but they solved it. That's the only problem that I can recall having with the solution.

I have an issue with the session server in terms of how it can scale, and where I can put my sessions. I know that there are some possibilities but I haven't found a solution for this problem yet.

The vendor should provide us with information concerning the best practices with respect to scalability. It may be that I'm too much of a novice, or that there are gaps in my knowledge because the product does not explain these features well, or perhaps what I'm looking for is not actually available.

At this time, we are very interested in the automation of the deployment process, and keeping track of deployment metrics. Adding these types of features would be helpful.

We would like to be notified when something goes wrong in the process. When something is not working, we should get an alert.

I would also like to have better control over how the application reacts to issues such as malfunctions. If something is not working properly then I would like to be able to failover or change how my application behaves.

They could flesh out some of their analytics a little more.

I can't think of any areas for improvement. It works pretty well.

The tool's configuration is complex.

I think this solution would be improved if free demos were available indefinitely.

In the next release, I would like to be able to run the static executables without a container. I couldn't run my application without a container because they prohibit running binary.

We have to do daily restarts of some processes, which is annoying, and the support for custom CI could be better.

Their support is good, but they can improve their response time.

They used to have MongoDB add-ons, but currently I think they've stopped and I'm not sure why. There is an issue because Heroku supports Docker container images, but not if you're using the continuous integration infrastructure. I really think Heroku should support Docker images on the CI infrastructure. For now, you cannot use those images and have to use the certified ones they provide for continuous integration and continuous delivery.

They have a free plan but it only provides three hours of service, after which you have to switch to a pay plan. It's when you start to scale the application it becomes costly. There should be more scalability options for storage. It would be nice to have more official stacks, to try and support more languages to stack officially.

We don't find the pipelines intuitive. The user experience could be better. Having to set up multiple apps, then a pipeline, seems like an overkill on the amount of work to do.

It's pricing is a little high and could be lowered.

Also, support could be better.
