This changelog covers product changes you can see and use. Internal refactors and infrastructure work are omitted unless they change what you experience.
Starter code is available immediately
A new blank project now opens its deterministic starter in Code immediately, including while the first Build is still working. The same starter can be downloaded before its first Git revision is saved. The unfinished Design systems preview was removed from Settings until it has a real product workflow behind it.Customization settings preview
Knowledge, Skills, and Design systems received dedicated Settings previews reachable from either the dashboard or a project. The Design systems preview was later removed until its underlying project workflow is ready.A single home for legal documents
The legal set is now stitched together under mythos.new/legal: one overview page, plus a sidebar on every legal page so you can move between the Terms of Service, Privacy Policy, and Cookie Policy without hunting through the footer.Cookie Policy
A standalone Cookie Policy now lists every cookie and browser-storage key Mythos sets — what each one does, how long it lasts, and how to manage it. Mythos sets only strictly-necessary first-party cookies; there are no advertising or third-party analytics trackers. A Manage cookie preferences button on the page reopens the same preferences dialog you saw on your first visit.Support page
mythos.new/support is now a real page: search the documentation directly from it, or jump to email support. Previously support was a footer link to an email address.Improvements
- The Privacy Policy was refreshed — the sub-processor list now matches exactly the services Mythos uses today, and the cookies section links to the new Cookie Policy.
- The cookie notice was reworked: it no longer covers the legal pages that document it, and the preferences dialog is fully keyboard-accessible.
- The Mythos mark on the sign-in page and the dashboard sidebar was redrawn as a clean vector.
Documentation lives at docs.mythos.new
These docs launched: guides for getting started, every workspace feature, publishing, and the Supabase integration, plus reference pages like the glossary and this changelog.Dashboard visual refresh
The dashboard content panel was reworked to sit flush on a calm neutral canvas — less chrome, more of your projects. See Dashboard overview.Removed
- Skills. The user-created Skills feature (shipped June 12) has been removed. Mythos still applies its built-in quality playbooks — including accessibility, redesign, and SEO review — automatically during builds; there is just no separate tab for authoring your own. The capability may return in an expanded form later.
Plan mode follows a fixed funnel
Plan mode now runs in a fixed order before any build: a short questionnaire about your project, then rendered design directions to choose between (including brand color palettes), then an editable plan you approve. Planning is free — credits are only spent when the approved build runs.The plan itself opens in a proper editor: change headings, reorder steps, and cut scope before you approve.Superseded (August 19, 2026): this entry records the June 30 behavior. Each accepted Plan AI turn now costs 1 credit; see Credits & pricing.Watch the build as it happens
The progress card during a build now streams what the agent is actually doing — reading files, writing components, installing packages — instead of a frozen “Building…” label. When the build finishes, the chat reply is a short summary of what was built, not a wall of internal reasoning.Every build delivers or refunds
Every generation now ends in exactly one of two states: a delivered, verified result — or a clean, plain-language message with a full refund. You never see a raw technical error, and you are never charged for a build that did not deliver.Builds that run out of time close to the finish line are also no longer discarded: if the result already passes the quality checks, it is delivered as-is instead of being thrown away and refunded. See Credits & usage.Template gallery with live previews
Every template in the gallery now has a live preview — a real running site you can click through before remixing — plus a filled-in detail page describing what’s inside.Careers page
Mythos is hiring: mythos.new/careers.Chat and history improvements
- Bookmarks — pin important turns in the chat and filter history down to just the pinned ones.
- Preview any earlier version — pressing Preview on an older turn shows the project as it was at that point, clearly marked as viewing mode.
- Batched questions — when the agent needs several answers, it now asks them as one form instead of one question at a time.
- The plan now opens as a side panel next to the chat instead of covering it.
Skills
Create reusable playbooks that teach Mythos how you want recurring work done, invoke them from a slash menu in chat, or import one from a GitHub repository or URL.Skills was removed on July 1, 2026 — see that entry. The built-in playbooks it bundled still run automatically during builds.
Chat attachments
A single + menu in the composer lets you attach a photo (the agent reads it as an image — great for design references and screenshots of bugs) or a file, which is committed into your project before the build runs so the agent can actually use it. See Chat attachments.Workspace reorganization
- Cloud and Settings are now top-level views in the workspace Services rail.
- Account settings moved into a dialog available from both the dashboard and the workspace; your credit balance now lives in the avatar menu. See Workspace editor.
Removed
- Connectors. The paste-an-API-key integrations system was removed. The supported way to add a database, auth, and storage is connecting your own Supabase project — see Supabase integration.
Database migrations apply automatically
When your own Supabase project is connected, schema changes the agent writes are now applied to your database during the build — with a safety gate that requires row-level security on new tables — and your TypeScript types are regenerated to match. Previously migrations were only written to the repo for you to run yourself. See Supabase integration.Connecting Supabase also posts a summary card into the chat, so the connection is part of your project’s history.Cloud console
Services → Cloud in the workspace is a full console for the Supabase project you connect — without leaving Mythos:- Database tables with editing and pagination, plus a SQL editor
- Users, storage (with a file browser — upload, download, delete), and secrets
- Edge functions, logs, and usage
Publishing, rebuilt
Publish now ships a real production build of your project to a publicyour-name.r21.dev address, through a guided wizard:- Pick your URL — choose the subdomain, and rename it anytime after publishing.
- SEO step — title, description, and social preview, with a suggested draft prefilled; upload a favicon. See SEO.
- Secret scan — publishing is blocked if the build would expose a secret.
- Works for Vite + React projects.
Good to know
- Each account can have up to 5 sites.
- Custom domains were added after this release and are now managed from More → Domains. See Custom domains for the current connection flow.
Files & artifacts
Projects gained a Files view. Ask Mythos for a downloadable PDF, CSV, XLSX spreadsheet, or chart and it appears there, alongside images the agent generated and files you attached in chat. You can also upload files into the project directly. See Files & artifacts.Code view polish
The workspace now has a three-tab view — Preview, Code, Files. The code editor gained per-filetype icons in the file tree, a Copy/Download header, and combined filename + content search. See Workspace editor.Crypto checkout
Credit packs are purchased through the new checkout at mythos.new/checkout, paid in USDT or USDC on the TRON network (TRC-20). The flow is non-custodial: you pay to a payment address and credits land after on-chain confirmation. See Credits & usage.Referral rewards
Share your invite link from the Share Mythos dialog. When someone you invited makes their first top-up of $30 or more, you receive 50 credits.keek.one is now mythos.new
The product was renamed from keek.one to mythos.new — same product, new name and domain. The old domain was retired. Full rename history lives in the glossary.Bring your own backend
The previously hosted backend (“Mythos Cloud”) was retired. Mythos is frontend-first: you connect your own Supabase project for a database, auth, and storage, so your data stays in your own account. See Supabase integration.Related
