A private alternative to a public pastebin
Yes. If you want a private place to put coding-agent output, use an account-scoped clipboard like ShareBit AI. Keep the public pastebin for text you want strangers to read. They are two different jobs, and most people reach for the wrong one because the pastebin is already open in a tab.
TL;DR
- A public pastebin is the right tool when you want a link anyone can open and read. That is its whole design.
- Coding-agent output is not public material. It names internal repositories, branches and hosts, and it is where stray secrets hide.
- ShareBit AI is the private, account-scoped alternative for agent output, but it is not encrypted. If your text is a credential, use an encrypted pastebin instead.
What a public pastebin is good at
A pastebin stores plain text and gives you back a link. Pastebin.com has done it since 2002: paste text, pick a language, get a URL.
Use a public pastebin when:
- You are answering a question on a forum or in an issue tracker and need a stable link to a snippet.
- You are sharing a stack trace with a maintainer who does not have access to your machine.
That is a feature, not a bug. Paste services separate public, unlisted and private modes: public pastes are visible to everyone and get crawled by search engines, unlisted ones need the direct link, and private ones are tied to an account. If your goal is a link anyone can open, a public pastebin is correct.
The problem when the text comes from a coding agent
Coding-agent output is different from a forum snippet because it was never written for an audience. It is working material such as a diff, a failing test, or a traceback. It carries context you would not choose to publish.
Look at a few agent transcripts and you will see the pattern: absolute paths with your username and machine name, internal repository and branch names, hostnames, the contents of a .env file, and now and then a token or connection string echoed into a log by accident. A pasted terminal log is one of the commonest places secrets appear in the wild; there are search engines built to trawl pastebin sites for leaked emails, passwords, API keys and tokens.
Combine that with how public pastebins behave. A public paste URL is durable and indexable. Once it is crawled, the "expires in one hour" setting does not un-crawl the copy, and the URL keeps working for anyone who has it. The mistake is structural, not personal: the default is "make this link work for everyone," the opposite of what agent output needs.
The manual ritual people use instead is just as bad: copy the diff, open a scratch gist or pastebin, remember to set it to secret, paste the URL back into the terminal, and never clean it up.
The honest part: if it is a secret, do not use ShareBit
This goes against us.
Pastebins like PrivateBin and scrt.link are built for secrets, and they are good at it. PrivateBin encrypts and decrypts in the browser with 256-bit AES in Galois Counter Mode, and the key lives in the URL fragment, so the server has zero knowledge of what it stores. scrt.link does the same as a hosted service: the key is generated on your device, embedded in the link, never sent to the server, and a secret is deleted after it is viewed.
ShareBit AI is not that. It is not end-to-end encrypted, the operator can technically read stored content, and it does not protect secrets. It is built for readable agent output a person will look at, not for a password, a private key or an access token where "the server cannot read it" is the requirement.
If the text is a credential, use an encrypted pastebin such as PrivateBin, scrt.link, or another encrypted tool your team trusts. Do not use ShareBit or a plain public pastebin. This page is meant to be useful, not to win every use case.
What ShareBit AI does differently
For agent output such as a diff, log, or traceback, the job is to keep the text out of public view and make it temporary. That is what ShareBit AI is.
- Account-scoped. There is no public sharing mode. A paste is readable only by the owning account and its paired agents, so there is no public URL to leak.
- Expires by default. 30 minutes is the default lifetime, up to 24 hours maximum. After expiry the body is unreadable.
- The agent has to ask first. The pairing instructs the agent to show a preview and get approval before it creates a paste. That is guidance, not server-enforced, as Limits below says.
- Agent-first. Coding agents pair once with a code and get their own revocable credential. There is no API key to copy for normal setup. The four tools are
sharebit_create,sharebit_list,sharebit_read, andsharebit_rename.
If that sounds more like a private clipboard than a pastebin, that is the point. See what is an AI clipboard and clipboard for AI agents for the category, and the ctxt.io alternative if you are comparing tools that publish agent output.
Comparison
| Public pastebin | Encrypted pastebin (PrivateBin-type) | ShareBit AI | |
|---|---|---|---|
| Readable Markdown / fenced code | Yes, with syntax highlighting | Yes, after the browser decrypts it | Yes, the intended use |
| Account-scoped | Optional; private pastes need an account | Usually anonymous; accounts optional | Yes, always |
| Public mode available | Yes, by design | No public directory; the full link is the access check | No public sharing mode |
| End-to-end encrypted | No | Yes, the key never reaches the server | No |
| Expiry | Optional, often long or never | Yes; burn-after-read is available | On by default, 30 minutes, 24 hours max |
| Built for secrets | No | Yes | No, built for readable agent output |
Expiry ranges differ by service. A self-hosted PrivateBin instance may allow anything from five minutes to a year, or no expiry at all, depending on its configuration. Hosted services publish their own limits. For example, scrt.link advertises ten minutes to thirty days. Check the service you plan to use.
Limits
- Not end-to-end encrypted. The operator can technically read stored content. Do not put credentials, private keys or tokens in it.
- No public mode. You cannot hand a ShareBit paste to someone outside your account. If a teammate needs the link, that is a different tool.
- Approval is guidance, not enforcement. The agent is instructed to preview and ask before uploading, but the server does not block an upload that skips it.
- No delete on demand. There is no delete tool over MCP and no "delete now" action; content is removed by the scheduled expiry job. Title and timing metadata are kept for 7 days after the body is gone.
- Size and time ceilings. 10 MB per paste, never split or truncated; 30 minutes by default, 24 hours maximum.
FAQ
Is a public pastebin private? Only if you use its private mode, which needs an account. Public and unlisted pastes are readable by anyone with the link, and public ones get indexed.
Can I make a pastebin link private? You can often make it unlisted or private, but the link still travels. If the text is sensitive, an encrypted pastebin where the server cannot read it is safer.
Is ShareBit encrypted? No, and we will not claim otherwise. It is account-scoped and temporary, which keeps agent output out of public view, but the operator can technically read what is stored. For secrets, use an encrypted pastebin.
Can my coding agent upload without asking me? It is instructed to show a preview and ask first, but that is guidance, not a server-side block. Treat the preview as your checkpoint.
Do I need an API key or a credit card? No. You sign in with Google, and the agent pairs once with a pairing code and gets its own revocable credential. It is free.
