Possible disadvantages of regular expressions 101

• Limited to Browser
  Regex101 is a web-based tool, and its usage is restricted to browsers with internet access, limiting its offline availability and performance in a development environment.
• User Interface Complexity
  For beginners, the user interface can be somewhat overwhelming due to the numerous options and features available, leading to a steeper learning curve.
• Performance Limitations
  While sufficient for most use cases, Regex101 may struggle with very large datasets or extremely complex regular expressions, causing performance issues.
• Dependency on External Product
  Relying on an external service means users are dependent on the platform's availability and continued maintenance, which can be a risk if the service goes down or changes significantly.
• Potential Overreliance
  Frequent use of Regex101 for developing regular expressions may lead to an overreliance on the tool, potentially hindering the development of strong, intrinsic regex skills.

Heroku features and specs

• Ease of Use
  Heroku offers an extremely user-friendly interface and a high level of abstraction, making it easy for developers to deploy, manage, and scale applications without worrying about the underlying infrastructure.
• Quick Deployment
  One of Heroku’s strongest points is the ability to deploy applications quickly using Git. Developers can push their code to Heroku with a simple command, streamlining the entire process.
• Scalability
  Heroku provides effortless scaling options by allowing developers to add more dynos (containers) with a single command to handle increased traffic and workload.
• Add-Ons Ecosystem
  Heroku offers a rich ecosystem of add-ons, such as databases, caching, monitoring, and more, which can be easily integrated into applications to extend their functionality.
• Automatic Updates
  Heroku automatically handles operating system and server updates, allowing developers to focus solely on their application code rather than maintenance tasks.
• Free Tier
  Heroku offers a free tier with sufficient resources to host small projects and learn the platform without incurring costs, making it accessible for beginners and small-scale applications.

Possible disadvantages of Heroku

• Cost
  While Heroku offers a free tier, the costs can quickly add up for larger applications and professional use. Paid plans and additional dynos or add-ons can become expensive.
• Performance
  Heroku’s performance can sometimes be suboptimal compared to other cloud providers, particularly when running high-performance or resource-intensive applications.
• Limited Control
  Heroku abstracts away a lot of infrastructure management, which can be a downside for developers who need fine-grained control over their environments and configurations.
• Dyno Sleeping
  Applications running on Heroku’s free tier experience 'dyno sleeping,' where the application goes to sleep after 30 minutes of inactivity, causing a delay when it wakes up after receiving a new request.
• Vendor Lock-In
  Relying heavily on Heroku’s ecosystem and platform-specific features can lead to vendor lock-in, making it challenging to migrate to another platform if needed.
• Add-On Costs
  The costs for add-ons can also become significant, as many useful features and integrations require paid add-ons, increasing the overall expense.
