 3# What is NoPaste?
 4
 5[NoPaste](https://nopaste.ml/) is an open-source website similar to Pastebin where you can store any piece of code, and generate links for easy sharing
 6
 7However, what makes NoPaste special is that it works with **no database**, and **no back-end code**. Instead, the data is compressed and **stored entirely in the link** that you share, nowhere else!
 8
 9### Because of this design:
10
11-   🗑️ Your data **cannot be deleted** from NoPaste
12-   🔞 Your data **cannot be censored**
13-   👁️ The server hosting NoPaste (or any clone of it) **cannot read or access** your data
14-   ⏳ Your data will be accessible **forever** (as long as you have the link)
15-   🔀 You can access your data on **every NoPaste clone**, including [your own](https://github.com/bokub/nopaste/wiki/Deploy-your-own-version-of-NoPaste)
16-   🔍 Google **will not index** your data, even if your link is public
17
18> **Note:** This project is a copy of [Topaz's paste service][topaz-example], with a reworked design and a few additional features (syntax highlighting, line numbers, line wrapping, embedding...)
19
20## How it works
21
22When you click on "Generate Link", NoPaste compresses the whole text using the
23[LZMA algorithm](https://en.wikipedia.org/wiki/Lempel%E2%80%93Ziv%E2%80%93Markov_chain_algorithm), encodes it in
24[Base64](https://en.wikipedia.org/wiki/Base64), and puts it in the optional URL fragment, after the first `#` symbol: `nopaste.ml/#<your data goes here>`
25
26When you open a link, NoPaste reads, decodes, and decompresses whatever is after the `#`, and displays the result in the editor.
27
28This process is done entirely **in your browser**, and the web server hosting NoPaste [never has access to the fragment](https://en.wikipedia.org/wiki/Fragment_identifier)
29
30For example, [this is the CSS code used by NoPaste][example]
31
32## Embedded NoPaste snippets
33
34You can include NoPaste code snippets into your own website by clicking the _Embed_ button and using the generated HTML code.
35
36Here is an example of generated code and how it looks (click on the screenshot to see the interactive version)

51## Maximum sizes for links
52
53NoPaste is great for sharing code snippets on various platforms.
54
55These are the maximum link lengths on some apps and browsers.
56
57| App     | Max length |
58| ------- | ---------- |
59| Reddit  | 10,000     |
60| Twitter | 4,088      |
61| Slack   | 4,000      |

63| Bitly   | 2,048      |
64
65| Browser         | Max length                | Notes                                   |
66| --------------- | ------------------------- | --------------------------------------- |
67| Google Chrome   | (win) 32,779 (mac) 10,000 | Will not display, but larger links work |
68| Firefox         | >64,000                   |                                         |

71| Android         | 8,192                     |                                         |
72| Safari          | Lots                      |                                         |
73
74## Generate NoPaste links
75
76NoPaste links can be created easily from your system's command line:
77
78```bash
79# Linux
80echo -n 'Hello World' | lzma | base64 | xargs -0 printf "https://nopaste.ml/#%s"
81
82# Mac
83echo -n 'Hello World' | lzma | base64 -w0 | xargs -0 printf "https://nopaste.ml/#%s"
84
85# Windows / WSL
86echo -n 'Hello World' | xz --format=lzma | base64 -w0 | printf "https://nopaste.ml/#%s" "$(cat -)"
87```
88
89## Deploy your own version of NoPaste
90
91NoPaste is just a bunch of static files, making it really easy to deploy on any kind of file server.
92
93Read [the wiki](https://github.com/bokub/nopaste/wiki/Deploy-your-own-version-of-NoPaste) to see how you can deploy your own version of NoPaste for free using Github Pages
