For running JavaScript code with dynamic parameters and transparent execution for automation tasks, CustomJS is a powerful contender. It lets you write and run your own JavaScript code with the ability to choose response types like Text, JSON, HTML, PNG, or PDF. The service can be invoked with direct browser links, POST requests, and HTML forms. It offers a freemium plan with 600 executions per month and several paid options, making it a good choice for automating tasks like generating invoices, sending emails and exporting data, and it integrates with services like Make, Salesforce, Airtable and Google Spreadsheets.
Another top contender is Pipedream, which offers an environment where you can build complex applications by running your own logic with Node.js, Python, Go or Bash. It can call more than 2,100 APIs through npm and PyPI packages, so it's easy to integrate with services like OpenAI, Salesforce and Microsoft Teams. With features like instant deployment and several pricing tiers, Pipedream can help you automate tasks across a range of services.
For a more secure and collaborative cloud development environment, check out RunCode. The service lets full-stack developers write code directly in their browser without installation and includes collaboration tools like real-time workspace sharing and generative AI-powered code completion. RunCode supports a wide range of programming languages and integrates with popular frameworks and databases, so you can get the flexibility and security you need as a solo developer or team.
