Share logs, code and configs instantly.
LogShare turns anything you paste into a link that expires. Line numbers, highlighting and search for whoever opens it. No login, no clutter, gone when you're done.
Free, no account. Paste anything and your link is ready to send.
The four tools developers reach for most.
Free, instant, and nothing you paste leaves your browser.
JSON Formatter
Format, indent, and validate JSON in your browser. Paste minified or messy JSON and get clean, readable output instantly — nothing leaves your browser.
Open JSON Formatter →Base64 Encoder / Decoder
Encode text to Base64 or decode Base64 back to plain text, including UTF-8 and URL-safe variants, instantly in your browser. No upload, no signup.
Open Base64 Encoder/Decoder →JWT Decoder
Decode a JSON Web Token to inspect its header and payload in your browser. No signature verification, no upload — the token never leaves your device.
Open JWT Decoder →Unix Timestamp Converter
Convert a Unix timestamp in seconds or milliseconds to a readable date in local time, UTC and ISO 8601, and convert dates back. Runs entirely in your browser.
Open Timestamp Converter →Three steps from terminal to teammate.
Paste your content
Drop in a log, a stack trace, or a config file. Logs are auto-detected as JSON, YAML, Nginx, Kubernetes and more.
Pick an expiry
Choose anywhere from 30 minutes to 7 days. When the link expires, the content is deleted. Nothing lives forever.
Share the link
Send it in Slack, a ticket, or a pull request. Viewers get line numbers, syntax highlighting, search and word wrap.
For the moments when pasting 400 lines into chat is the wrong answer.
Share kubectl and docker logs
Paste kubectl logs, docker logs or journalctl output and hand the on-call channel one link instead of a wall of text.
Stack traces and CI output
Share a failing build log or a Python, Java or Node traceback with highlighting, line numbers and in-page search.
Configs behind a PIN
Reviewing a config with real hostnames in it? Open a private room, set a PIN, and share the link. Only people with the PIN get in, and it expires on its own.
Live code rooms
Open a collaborative code editor and edit together in real time. No accounts, just a URL you can send to anyone.
Free utilities that run entirely in your browser.
Formatters, validators and converters for JSON, YAML, Docker and Kubernetes. Nothing you paste is uploaded. New to one? Read the tutorials.
K8s YAML Validator
Check a Kubernetes manifest for YAML syntax errors, missing required fields, and common misconfigurations — right in your browser, before you apply it.
JSON Minifier
Strip whitespace and line breaks from JSON to shrink its size before sending it over the wire or embedding it inline — runs entirely in your browser.
JSON Diff
Compare two JSON documents by structure and see exactly which keys were added, removed or changed, with full paths. Key order and whitespace are ignored.
YAML → JSON
Convert YAML to JSON instantly in your browser — paste a Kubernetes manifest, Docker Compose file, or any YAML document and get equivalent JSON.
JSON → YAML
Convert JSON to YAML instantly in your browser — useful for turning an API response or config into a Kubernetes-manifest-friendly format.

Frequently asked questions
What is LogShare?
LogShare is a free tool for sharing logs, code and configuration through a temporary link. You paste, choose how long the link should live, and share it. When it expires, the content is permanently deleted.
Do I need an account to share a log?
No. There is no signup, no login and no email required. Paste your content, click Create Share Link, and send the URL.
How long do shared logs and pastes last?
You choose an expiry of 30 minutes, 1 hour, 6 hours, 24 hours or 7 days when you create a share. The default is 24 hours.
Is it safe to share logs that contain secrets?
Never share passwords, API keys, access tokens or private keys. Anyone with a share link can view it until it expires. When the content is sensitive, use a Private Room: only people who know the PIN can open it, and it is deleted when it expires.
What is a Private Room?
A live code room protected by a PIN you choose. Anyone opening the link sees a locked screen until they enter the PIN; the server sends nothing from the room before that. Rooms expire after 30 minutes, 1 hour, 6 hours or 24 hours and are then deleted.
What is the maximum size?
Pasted logs, text and config can be up to 5 MB each.
Can I share kubectl, docker or journalctl output?
Yes. Pipe the output to your clipboard or copy it from your terminal, paste it into LogShare, and pick a type such as Kubernetes, Docker, Nginx or Generic application log. The viewer adds line numbers, syntax highlighting, search and word wrap.
Are shared pages indexed by search engines?
No. Every share and file page is marked noindex and blocked in robots.txt, and links use random, non-sequential tokens. Only the public landing pages and developer tools are indexable.
