About gitime.dev
gitime.dev is an independent, privacy-first collection of developer tools that run entirely inside your own browser. There are no accounts, no uploads and no tracking of what you paste. This page explains what the site is, who maintains it, how it works and how it stays free.
What gitime.dev is
gitime.dev is a set of small, fast, single-purpose utilities for everyday development work — formatting and validating JSON, converting between JSON, CSV and YAML, decoding JWTs, encoding Base64, generating hashes and checksums, comparing text with a diff checker, inspecting certificates, compressing images and more. Each tool does one job, loads quickly, and works without a sign-up screen getting in the way.
The whole site is deliberately simple. You open a tool, paste or drop your input, and get a result. There is nothing to install, no extension to add, and no dashboard to learn.
The one idea behind everything: local-only
The defining principle of gitime.dev is that your data never leaves your device. Every converter, decoder, formatter, hasher and diff tool is implemented as client-side JavaScript. When you paste an API token, a private key, a customer CSV or a configuration file, that content is processed in your browser's memory and is never transmitted to or stored on our servers. When you close or reload the tab, it is gone.
This matters because developer tools routinely handle sensitive material: production secrets, signed tokens, internal schemas, personal data inside sample files. Many online utilities quietly send that input to a backend to do the work. gitime.dev does not. The privacy guarantee is not a policy we promise to honour — it is a property of how the tools are built. If there is no upload code, there is no upload.
Why it exists
gitime.dev started from a simple frustration: needing to quickly format some JSON or decode a token, searching for a tool, and landing on a page that was slow, covered in pop-ups, demanded a login, or — worst of all — asked you to paste a secret into a box that sent it somewhere unknown. The goal here is the opposite: open the page, do the thing, trust that nothing left your machine, and move on.
Speed and privacy are the two values the site optimises for. Tools are kept lightweight so they load instantly even on a slow connection, and they are designed to keep working offline once the page is open, because they do not depend on a server round-trip to function.
Who builds and maintains it
gitime.dev is an independent project maintained by a developer based in Taiwan, not a company or a venture-backed startup. It is built and run by one person who uses these same tools daily. That independence is why the site can stay focused on being genuinely useful rather than on capturing accounts or harvesting data.
Feedback shapes what gets built. If a tool is missing an option you need, behaves unexpectedly, or you wish a new utility existed, that input directly influences the roadmap. The best way to reach the maintainer is by email at [email protected], or via the contact page.
How gitime.dev stays free
Running a website has real costs — a domain, hosting and time. To keep every tool free and open to everyone without paywalls or accounts, gitime.dev is supported by advertising served through Google AdSense. Ads are placed around the content, never inside the working area of a tool, so they do not interrupt what you came to do.
Advertising is the only thing on the site that involves third-party cookies, and you are always in control of it. Full details — including how to opt out of personalised ads under GDPR and US state privacy laws — are in our Privacy Policy. We do not sell your data, because we do not collect identity data about you in the first place.
What we will never do
- Upload your tool input. Processing stays on your device, by design.
- Require an account. No name, no email and no login is needed to use any tool.
- Build tools that help break the law. The tools are for working with your own authorised data and for legitimate development and debugging only.
- Hide how the site is funded. Advertising and the limited third-party services it relies on are disclosed plainly in the Privacy Policy.
Use the tools responsibly
The decoders and inspectors on gitime.dev (for JWTs, Base64, certificates and similar) are intended for developers debugging their own data. Please do not use them on data you are not authorised to access. The tools are provided for reference and development purposes; see our Terms of Use for the full disclaimer.
