But, DO NOT expect users to Sign-up first to try what it does. My experience with SAAS products (I created https://extracttable.com and nextround.ml, notyce.me) is the high visit to sign-up conversion when you provide a demo UI on the site, with NO SIGN-UP needed, upfront.
Diff: extracttable without demo 29 sign-ups in 4 weeks + 0 paid, with demo 31 in 2 weeks + 18 paid users. Not just sign-ups you get the paying customers much faster than you would expect.
BTW, you can signup and create a project with early access package for free. Then you will get access token to perform api requests for url to pdf and html to pdf.
You can also create templates. Which you can design using mustache (more templating engine coming soon). Then just pass context data to generate pdf via api.
Imagine you have build a mobile application or cloud function from which you want to create some sort of pdf. You can use templates to separate pdf design from you application code and just perform api requests to generate pdf. And if you want to modify your design, just change the template, your application code is untouched.
Thanks for your advice. Also, for now I have used bootstrap, ace editor, backend on django and the api backend in node js etc.
Your service looks awesome too.
Btw, "what do you use" I meant for documentation. Did you use any API service that generates documentation? I used postman for ET, no complains - but I would like to have the option of changing the Coding language at the console screen not at the top of screen, like it is in postman, now.
