DevTool House is a free collection of practical tools for developers, freelancers, students, and small businesses. It includes developer utilities, web debugging tools, freelance calculators, Pakistan tax tools, and productivity helpers — all in one simple place.
DevTool House was built to make common technical and business tasks easier to complete. Instead of opening different websites for formatting JSON, decoding JWTs, checking DNS records, creating invoices, or calculating freelance income, users can find these tools in one clean and accessible place.
Each tool is built to be easy to open, understand, and use without unnecessary steps.
The platform focuses on tasks developers, freelancers, students, and businesses often need during real projects.
Pakistan-specific tools such as income tax, freelance tax, electricity bill, and currency utilities are included for local users.
DevTool House continues to improve based on practical needs, user suggestions, and real workflow problems.
DevTool House started from a simple problem: many everyday tools were scattered across different websites. Formatting JSON, decoding tokens, checking API responses, looking up DNS records, or generating invoices often meant switching between multiple tabs.
I wanted to create a place where these small but important tasks could be handled quickly, without extra clutter or complicated steps.
Over time, DevTool House grew into a collection of developer utilities, web tools, freelance calculators, Pakistan-specific calculators, and productivity tools for people who work online.
