git clone https://github.com/willchen96/mike.git
cd mike

npm install --prefix backend
npm install --prefix frontend

cp backend/.env.example backend/.env
cp frontend/.env.local.example frontend/.env.local

Then fill in the values. See Environment Variables below.

For a new Supabase database, open the Supabase SQL editor and run the contents of backend/schema.sql.

For an existing database, do not run the full schema file over production data. Apply the incremental files in backend/migrations/ instead.

npm run dev --prefix backend

Backend runs on http://localhost:3001.

npm run dev --prefix frontend

Open http://localhost:3000.

Sign up in the app. If you did not set provider keys in backend/.env, open Account > Models & API Keys and add an Anthropic, Gemini, or OpenAI API key.

Supabase values come from the project dashboard. Use the project URL for SUPABASE_URL / NEXT_PUBLIC_SUPABASE_URL, the service role key for SUPABASE_SECRET_KEY, and the anon/public key for NEXT_PUBLIC_SUPABASE_PUBLISHABLE_DEFAULT_KEY. If your Supabase project shows multiple key formats, use the legacy JWT-style anon and service role keys expected by the Supabase client libraries.

Provider keys are only needed for the models and email features you plan to use. Model provider keys can be configured in backend/.env for the whole instance, or per user in Account > Models & API Keys. If a provider key is present in backend/.env, that provider is available by default and the matching browser API key field is read-only.

Sign-up confirmation email never arrives. Confirmation emails are sent by Supabase Auth, not by Mike. For local development, the simplest fix is to disable email confirmation in Supabase > Authentication > Providers > Email. For production, configure custom SMTP in Supabase; the built-in mailer is heavily rate-limited and may be restricted on newer projects.

The model picker shows a missing-key warning. Add a key for that provider in Account > Models & API Keys, or configure the provider key in backend/.env and restart the backend.

DOC or DOCX conversion fails. Install LibreOffice locally and restart the backend so document conversion commands are available on the process path.
