# ZeroLog

> Give your coding agent Superpowers. A real Linux workspace for your AI agent. Install software, write code and run your services, with root access and files that stay.

Preview: ZeroLog is not open to the public yet. Accounts are created on request.

Every public page is server-rendered HTML and has a Markdown version: add `.md` to the path
(the home page is https://zerolog.ch/index.md) or request the page with `Accept: text/markdown`.
The whole documentation, the home page and the pricing in one file: https://zerolog.ch/llms-full.txt
The signed-in app (/next/) and the API (/api/) are private and not meant for crawling.

## Docs

One link per capability. Overview: https://zerolog.ch/docs.md

### Getting started

- [First 5 minutes](https://zerolog.ch/docs/start.md): Request access. New accounts currently need an invitation. Use Request access. Once invited, create an account with a username and password. You can add an email address later unde…
- [How it fits together](https://zerolog.ch/docs/concepts.md): Four things, and it helps to keep them apart: Chat : the conversation.

### Access

- [Waitlist email links](https://zerolog.ch/docs/waitlist.md): Opening a waitlist email link only shows a confirmation page.

### Chat

- [Chat basics](https://zerolog.ch/docs/chat.md): Type, send, read. The reply streams token by token and the cost strip under it fills in while it writes. Edit a message to fork the conversation from that point. The original stays…
- [Choosing a model](https://zerolog.ch/docs/models.md): The picker above the input lists every available model with its price per million tokens and its context length.
- [Temporary model pause](https://zerolog.ch/docs/provider-pause.md): Featherless models are temporarily unavailable to customer accounts while ZeroLog completes the provider's data protection terms and confirms its right to offer those models.
- [Files and images in chat](https://zerolog.ch/docs/attach.md): Attach with the clip, or paste an image straight into the box.
- [Long conversations](https://zerolog.ch/docs/compaction.md): When a thread approaches the model's context limit, older turns are compacted into a summary so the conversation can continue instead of failing.
- [Prompt optimiser](https://zerolog.ch/docs/prompt.md): A separate area for building and refining prompts.
- [Skills](https://zerolog.ch/docs/skills.md): Reusable instruction files the AI can load when relevant, instead of you re-explaining a workflow every time.
- [Memory and writing style](https://zerolog.ch/docs/memory.md): Facts worth carrying between conversations: how you like code formatted, what stack you use, what you are working on, plus an optional writing-style profile so replies sound the way you want.
- [Context stitching](https://zerolog.ch/docs/stitch.md): Context index can bring relevant parts of your past chats into a new conversation.
- [Research mode](https://zerolog.ch/docs/research.md): For questions that need sources rather than an opinion.
- [Voice](https://zerolog.ch/docs/voice.md): Speak instead of typing, and have replies read aloud.
- [Buddy](https://zerolog.ch/docs/buddy.md): Buddy is a small coding pet that lives in the corner of your chat.
- [Import from ChatGPT and Claude](https://zerolog.ch/docs/imports.md): Bring exported conversations into ZeroLog.

### Compute

- [Containers](https://zerolog.ch/docs/containers.md): Open Containers → New container, choose an available Linux image, set a name and create your workspace.
- [Isolation](https://zerolog.ch/docs/isolation.md): Your workspace is its own container, not shared with any other user.
- [Command approval](https://zerolog.ch/docs/approval.md): Every command the AI wants to run appears in full and waits.
- [Files](https://zerolog.ch/docs/files.md): A real file tree of the container. Browse, open in the editor, upload, download. Download a single file or a whole folder as an archive. Edits you make are immediately what the AI…
- [Terminal](https://zerolog.ch/docs/terminal.md): A shell in the same container, available mid-task without stopping the agent.
- [Network drive (SMB)](https://zerolog.ch/docs/smb.md): Use WebDAV in the storage panel to open a workspace as a network drive from your computer.
- [Public ports](https://zerolog.ch/docs/ports.md): Start something listening in the container, then publish that port.
- [Custom domains](https://zerolog.ch/docs/domains.md): On eligible plans, add your domain in the account's Custom domains panel and choose a published port.
- [Outbound network](https://zerolog.ch/docs/egress.md): Container internet access passes through ZeroLog's network protections.
- [Virtual machines](https://zerolog.ch/docs/vms.md): Create a virtual machine from one of the available templates when your work needs a separate operating system.
- [Desktop control](https://zerolog.ch/docs/desktop.md): For graphical work, a desktop session in its own section.

### Agents

- [/goal](https://zerolog.ch/docs/goal.md): Type /goal and the condition that means "done": /goal every test in ~/budget passes The chat keeps its goal and carries on as usual.
- [/ultracode](https://zerolog.ch/docs/ultracode.md): /ultracode is a switch, not a job. Turn it on, and the model in this chat may split a large task across several agents in your container when that is faster than doing it alone. It…
- [Jobs and logs](https://zerolog.ch/docs/jobs.md): Every long-running piece of work (an agent run, an import, a snapshot) appears under Jobs with its state and its log.
- [Scheduled tasks](https://zerolog.ch/docs/tasks.md): Give an agent a job and a time: a nightly build, a daily check, a weekly summary.
- [Invisible automation](https://zerolog.ch/docs/automation.md): Standing permissions for routine actions, with an approval queue for anything outside them, plus a digest of what was done.
- [Website Builder](https://zerolog.ch/docs/website-builder.md): The website builder turns a natural-language description into a complete, deployable web project directly inside the chat using the /site command.

### Browser

- [Browser extension](https://zerolog.ch/docs/extension.md): Use ZeroLog chats in your browser side panel to get help with pages you can access.

### Research and security

- [Trust and security](https://zerolog.ch/docs/trust.md): ZeroLog is operated by one person, hosted in Switzerland, and built so what happens to your data can be checked rather than taken on trust.
- [Deep research](https://zerolog.ch/docs/deepresearch.md): A longer, structured version of research mode for questions where you want a report rather than an answer.
- [Legal research](https://zerolog.ch/docs/recht.md): Ask a legal question and ZeroLog searches supported primary legal sources.
- [Security scan](https://zerolog.ch/docs/pentest.md): A security scan checks a website you are authorised to test and reports findings you can review.
- [Live web search and sources](https://zerolog.ch/docs/grounded-search.md): Grounded web search retrieves current pages and checks that cited quotations match their source text.

### Media

- [Image generation](https://zerolog.ch/docs/images.md): Ask for an image in a normal message. The AI picks a suitable model, or you name one. Turn image generation on with /image on. Use /image off to turn it off again. Fast and cheap f…
- [Gallery and backgrounds](https://zerolog.ch/docs/gallery.md): Every image you generate and every image you upload collects in the gallery.
- [Design engine](https://zerolog.ch/docs/design-engine.md): With /design, the AI in your chat does the design work itself.

### Connect

- [Connectors](https://zerolog.ch/docs/connectors.md): Connect your account to an optional service, such as an image service or a Google account.
- [Machine-readable versions](https://zerolog.ch/docs/machine.md): Use ZeroLog’s Markdown pages to read documentation in an AI tool or fetch it from a script.
- [Push notifications](https://zerolog.ch/docs/push.md): Get told when a long run finishes or an approval is waiting, instead of watching a tab.
- [Webhooks](https://zerolog.ch/docs/webhooks.md): Let an outside system trigger work here, or be told when something finished.
- [Sharing a container](https://zerolog.ch/docs/share.md): Container sharing is not available yet. You cannot invite another person to a container from ZeroLog today.
- [Android app](https://zerolog.ch/docs/app.md): ZeroLog for Android 2.0 is a native app: chat, chat list, Compute, jobs and your container's files are drawn by the app itself and talk to zerolog.ch directly, not through a web page inside the app.
- [Claude Code and other CLIs](https://zerolog.ch/docs/cli.md): Use supported command-line tools with a vendor account or with models available through ZeroLog.
- [ZeroLog Code](https://zerolog.ch/docs/zerocode.md): ZeroLog Code is based on OpenCode and connects the terminal client to your ZeroLog account.

## Models

Customer models come from one inference provider and are paid from one ZeroLog credit balance at the
provider's rate plus 2 %. Pick a model per chat and switch mid-conversation; the chat keeps its history.
With your own provider key, that traffic is billed by the provider and ZeroLog adds no margin.

- [Choosing a model](https://zerolog.ch/docs/models.md)
- [Your own API key](https://zerolog.ch/docs/byok.md)
- [Terms of Service 1.3: one inference provider](https://zerolog.ch/news/terms-1-3-one-provider.md): This notice also explains what happens when a workspace stops during Auto-Sync or a security scan.

## Security

- [Two-factor authentication and passkeys](https://zerolog.ch/docs/mfa.md): Sign-in runs through ZeroLog's own sign-in service, Keycloak at auth.zerolog.ch, on the operator's servers in Switzerland.
- [Secrets vault](https://zerolog.ch/docs/vault.md): Store credentials the AI needs (a deploy token, a database password) encrypted, and attach them to a chat when needed.
- [Key proxy for third-party keys](https://zerolog.ch/docs/keyproxy.md): Store an API key for a third-party provider (Cloudflare, Tailscale, Stripe, and others) and agents in your chats can use it without ever seeing the real value.
- [Your own API key](https://zerolog.ch/docs/byok.md): Already paying a provider? Add your key and that usage goes to your account there instead of your ZeroLog credit.
- [Your own vendor subscription](https://zerolog.ch/docs/byoagent.md): Sign a CLI in with your own account and it runs on your subscription instead of your credit here.
- [Anonymous chats](https://zerolog.ch/docs/anon.md): An anonymous chat keeps its saved messages private to you.
- [Zero data retention](https://zerolog.ch/docs/zdr.md): ZeroLog shows whether zero data retention was enforced for an answer, stated generally by the provider, or not guaranteed.
- [Command approval](https://zerolog.ch/docs/approval.md)
- [Outbound network](https://zerolog.ch/docs/egress.md)
- [Reporting a vulnerability](https://zerolog.ch/.well-known/security.txt): security.txt (RFC 9116)
