ValidateHTML's answer
Instead of opening 5 different tabs (W3C for HTML, JSONLint for JSON, separate tools for meta tags, Open Graph, accessibility), ValidateHTML combines everything in one interface. Plus you get a quality score that tells you exactly where you stand.

ValidateHTML's answer
I was tired of opening 5 or 6 different tabs every time I needed to validate my code before deploying. W3C for HTML, JSONLint for JSON, random sites for meta tags. So I built one tool that does everything, with a quality score to instantly know where you stand.

Fx improves this with an interactive JSON processor made for developers. It combines viewing capabilities with powerful transformation functions that make complex data manipulation simple. - Source: dev.to / about 1 year ago
Coincidentally, yesterday I decided I needed a JSON TUI and landed on fx (https://github.com/antonmedv/fx), which seems to have come out of the Wave terminal project and looks quite similar to jless. Also uses vim keybindings. - Source: Hacker News / almost 2 years ago
This is great, I could see myself using it daily. The only hindrance I've found so far is navigating large responses. Would be cool to have some way to collapse chunks of JSON (a la https://github.com/antonmedv/fx), or even just more vim key navigation, like G/gg, %, {/}, and search. - Source: Hacker News / about 2 years ago
Neat! You mentioned not getting the hang of jq, have you played with fx? Source: about 3 years ago
This looks like something I'd use often. Thanks for creating it! For anyone who's not familiar, Anton is also behind the highly useful fx[0] for wrangling JSON data in the terminal. [0] https://github.com/antonmedv/fx. - Source: Hacker News / over 3 years ago
