About HeffTools
HeffTools is a collection of practical utilities built for DevOps engineers, SREs, and backend developers who just want tools that work — without ads, distractions, or nonsense.
The web tools are designed for fast answers during day-to-day work: debugging a cron schedule, validating a regex, converting data formats, generating secrets, or checking network details during an incident.
When those same tasks need to be automated, the exact same logic is available as stable, production-ready APIs.
Why this exists
Most online “developer tools” sites optimize for page views, ads, or SEO — not for engineers actually trying to get work done.
HeffTools exists because the author kept running into the same problems:
- Useful tools buried under ads and popups
- Pages bloated with tracking scripts
- Inconsistent results between web tools and APIs
- “Free” tools that break or disappear without warning
This site takes the opposite approach: fewer tools, done carefully, with predictable behavior and a long-term maintenance mindset.
Ad-free by design
HeffTools does not run ads. There are no ad networks, no behavioral tracking pixels, and no dark patterns.
Ads are a poor fit for infrastructure tooling. They add noise, hurt trust, and push sites toward shallow content instead of reliable engineering.
Instead, HeffTools is supported through optional paid API plans for users who need higher limits, production usage, or integration into CI/CD pipelines and internal systems.
Who it’s for
- DevOps and platform engineers
- SREs and on-call responders
- Backend developers
- Small teams and solo builders running real systems
If you value simple tools, clear output, and predictable behavior, you’re in the right place.
How it works
The free web tools and the paid APIs share the same backend logic. What you see in your browser is the same behavior you’ll get when calling the API from your own code.
API access is provided via RapidAPI to keep key management, quotas, analytics, and billing simple and transparent.
Who runs this
HeffTools is built and maintained by an engineer who works with Linux, infrastructure, automation, and production systems.
It’s not a venture-funded startup and it’s not a content farm. The goal is to build a small set of tools that remain useful, stable, and available over the long term.
Contact & feedback
Bugs, feature requests, and practical feedback are welcome. If something is unclear or doesn’t behave as expected, that’s considered a bug.
Get in touch if you have questions or want to suggest an improvement.
“If a tool here ever feels noisy, slow, or unreliable, it’s a bug — not a business model.”
