Rebrand

Every place the name "CrabStack", the logo, the colours, the page metadata and the email sender live. There is no brand generator: every file below is edited by hand, and two are regenerated afterwards.

Find them yourself with:

git grep -n -i crabstack -- . ':!docs' ':!*.md' ':!*package-lock.json'

Name and metadata (frontend)

• frontend/app/layout.tsx: the site-wide metadata (title, description, openGraph.siteName).
• frontend/app/page.tsx: the landing page's metadata, the logo text in the nav and the footer, and all the landing copy.
• Page titles of the form '... | CrabStack' and the logo link at the top of each page: app/settings/page.tsx, app/signin/page.tsx, app/signin/SignInForm.tsx, app/pricing/page.tsx, app/billing/success/page.tsx, app/blog/page.tsx, app/blog/[slug]/page.tsx, app/privacy/page.tsx, app/terms/page.tsx.
• frontend/app/llms.txt/route.ts: the text served at /llms.txt.

Logo and icons

• frontend/app/icon.svg: the favicon.
• frontend/app/apple-icon.tsx: the iOS home-screen icon, drawn in code.
• frontend/app/opengraph-image.tsx: the social preview card (APP_NAME, TAGLINE, STACK, colours, mark). twitter-image.tsx re-exports it.
• frontend/public/rocketman.svg: the illustration on the 404 page (app/not-found.tsx).

The three icon files share one placeholder mark; change all three. The apple icon and the social card are rendered by Next.js at build time, so there is no image file to replace unless you delete the .tsx and drop in an apple-icon.png or opengraph-image.png instead.

Colours

• frontend/app/styles/_palette.scss: every SASS module reads its colours from here.
• These copy palette values by hand and must be changed with it: frontend/app/globals.css (page background), themeColor in frontend/app/layout.tsx, the constants at the top of frontend/app/opengraph-image.tsx and frontend/app/apple-icon.tsx, and the fill in frontend/app/icon.svg.

Email sender

• SMTP_FROM (backend app mail) and EMAIL_FROM (magic-link mail): set them in your deploy's env. The defaults, [email protected], are in backend/.env.example, frontend/.env.example and docker-compose.yml.
• frontend/lib/magic-link-email.ts: the sign-in email's markup and button colour.
• backend/src/scripts/seed.ts: the sample campaigns' subject and body (seed data only).

Backend and API

• backend/src/main.ts and backend/scripts/dump-openapi.ts: the API title and description (setTitle, setDescription). Change both, then regenerate openapi.json and the frontend types (step 8 of recipe 1), or verify fails on drift.
• backend/src/mcp-admin/mcp-admin.service.ts, mcp-admin-tools.service.ts and mcp-admin.module.ts: the admin MCP server's name, description, instructions and OAuth consent page title.

Leave these alone

• LICENSE: the licence you received the template under. The grep above lists it, but it is a legal document, not branding.
• [email protected] in backend/migrations/003_*, 006_* and src/mcp-admin/mcp-admin-user.constants.ts: the identity of a row already in your database. It is never shown to users.
• The database name crabstack and the compose project name in docker-compose.yml, deploy/ and .github/workflows/ci.yml: renaming them points a running deploy at a new, empty database and volume. Change them only on a fresh install, and in every file at once.
• name in backend/package.json and frontend/package.json, and the comments in deploy/ and verify.sh: harmless to change, never seen by users.

Afterwards

Run npm run format in backend/ and frontend/: a shorter name can let prettier join a wrapped line, and format:check fails otherwise. Then run ./verify.sh.

What the test run found

Replacing "CrabStack" with "Acme" in every file under "Name and metadata", "Backend and API" and the email sender defaults, then regenerating openapi.json and the types, failed verify once at format:check (src/mcp-admin/mcp-admin.module.ts, where the shorter title fitted on one line). After npm run format: verify all green. No spec asserts the brand name.
