Heroku
Cloud platform that lets developers build, deliver, and scale apps without managing infrastructure
About Heroku
Heroku is a cloud platform as a service (PaaS) owned by Salesforce that enables developers to build, deploy, and scale modern applications. It abstracts away infrastructure management with managed runtimes, databases, and add-ons, letting teams focus on writing code rather than managing servers. Heroku supports multiple programming languages including Node.js, Ruby, Python, Java, PHP, and Go.
Pros & Cons
Pros
- Extremely easy deployment — push to Git and your app is live in minutes
- Fully managed infrastructure eliminates server maintenance and DevOps overhead
- Rich add-on marketplace with 150+ integrations for databases, monitoring, and services
- Excellent developer experience with CLI tools, review apps, and pipelines
- Supports multiple languages and frameworks out of the box
- Automatic SSL, security patches, and compliance handling
Cons
- Significantly more expensive than competing PaaS and IaaS providers at scale
- No free tier — even the cheapest Eco plan costs $5/month
- Limited infrastructure control compared to AWS, GCP, or self-hosted solutions
- Dyno sleeping on Eco plan causes cold start delays for infrequently visited apps
- Vendor lock-in can make migration to other platforms challenging as apps grow
