Why use online dev tools?

Whether you're debugging an API response with our JSON Formatter or optimizing assets with our Base64 Encoder, browser-based tools save time.

SFWeb provides these utilities free of charge to support the developer community in Montreal, Toronto, and beyond. All processing happens in your browser—we don't store your data.

Need something more powerful?

These tools are great for quick tasks. But if you need custom data processing pipelines, API integrations, or automated workflows for your business, we can build them.
