Pitchbar reads its configuration from the standard Laravel .env, with overrides for some keys available via the platform admin's App Settings page so you can swap Stripe / mail / LLM credentials without redeploying.

Required

Variable	Why
`APP_KEY`	Encryption master key. Generate with `php artisan key:generate`. Never rotate without a re-encrypt migration.
`APP_URL`	Public URL, used to build widget snippets, OAuth callbacks, signed URLs.
`DB_*`	Postgres connection.
`REDIS_HOST`	Cache, sessions, queue, hot-path retrieval cache, conversation history cache.
`QUEUE_CONNECTION`	Set to `redis` in production.
`SESSION_DRIVER`	`redis` in production.
`CACHE_DRIVER`	`redis`.
`WIDGET_JWT_SECRET`	HS256 signing secret for visitor JWTs. ≥ 32 random bytes.

LLM provider

At least one of the following:

Variable	Provider
`CLOUDFLARE_ACCOUNT_ID` + `CLOUDFLARE_API_TOKEN`	Cloudflare Workers AI (preferred). Auto-binds Llama 3.3 70B + bge-base-en-v1.5.
`OPENAI_API_KEY`	OpenAI direct.
`OPENROUTER_API_KEY`	OpenRouter (router across many providers).

Set LLM_PROVIDER to force a binding (cloudflare, openai, openrouter). When unset, the resolver picks based on which keys are available, in the priority above.

Vector store

Variable	Provider
`CLOUDFLARE_VECTORIZE_INDEX`	Cloudflare Vectorize index name. Uses `CLOUDFLARE_ACCOUNT_ID` + token. Default `pitchbar-chunks`.
`QDRANT_URL` + `QDRANT_API_KEY`	Qdrant.

Set VECTOR_PROVIDER to force. Auto-binds based on available keys (Vectorize preferred).

Crawler

Variable	Strategy
(uses `CLOUDFLARE_*`)	Cloudflare Browser Rendering. Preferred.
`BROWSERLESS_TOKEN` + `BROWSERLESS_URL`	Browserless fallback.
(none)	Plain HTTP. Free; no JS rendering.

Variable	Purpose
`CRAWL_MAX_PAGES_PER_SOURCE`	Max pages fan-out per Source. Default 500 (raised from 25 — buyers adding 100-URL sitemaps were silently losing 75 pages). Cap applies after sitemap-index recursion + dedupe.
`CRAWL_PAGE_DISPATCH_DELAY`	Per-page delay (seconds) when fanning out sitemap pages so Cloudflare Browser Rendering's small per-account concurrency doesn't 429. Default `2`.
`CLOUDFLARE_BROWSER_RENDERING`	Set to `false` to force the Browserless / plain-HTTP path even when Cloudflare keys are present. Default `true`.

RAG / retrieval

Variable	Purpose
`RAG_CONFIDENCE_THRESHOLD`	Default similarity threshold for newly created agents. `0.5` for Cloudflare bge-base-en-v1.5 (its ANN cosine peaks lower than OpenAI's); `0.78` for OpenAI text-embedding-3-small. Auto-resolves based on `LLM_PROVIDER`.
`RAG_RERANK_ENABLED`	Set to `false` to disable the bge-reranker-base cross-encoder pass. Default `true` when Cloudflare keys are present.
`VECTOR_DIM`	Embedding dimension override. Leave unset to auto-resolve from the configured embed model via the known-model map (bge-base=768, bge-m3=1024, text-embedding-3-small=1536, etc.). Set explicitly only when pointing at an unlisted model. Changing this on an existing install needs `php artisan vector:rebuild-index` — the Vectorize index is provisioned at the dim active when it was first created and cannot be resized in place.

Cloudflare AI Gateway (optional)

Variable	Purpose
`CLOUDFLARE_AI_GATEWAY_URL`	If set, Workers AI calls route through Cloudflare's AI Gateway — observability, caching, rate limits.
`CLOUDFLARE_CHAT_MODEL`	Default `@cf/meta/llama-3.3-70b-instruct-fp8-fast`.
`CLOUDFLARE_EMBED_MODEL`	Default `@cf/baai/bge-base-en-v1.5`.
`CLOUDFLARE_VECTORIZE_INDEX`	Vectorize index name. Default `pitchbar-chunks`.
`OPENROUTER_CHAT_MODEL`	OpenRouter chat model slug. Default `meta-llama/llama-3.3-70b-instruct:free`.
`OPENROUTER_EMBED_MODEL`	OpenRouter embedding model. Default `text-embedding-3-small`.
`QDRANT_COLLECTION`	Qdrant collection name when using the Qdrant vector store fallback. Default `pitchbar_chunks`.

S3 / R2 (object storage for file uploads)

Variable	Purpose
`AWS_ACCESS_KEY_ID` + `AWS_SECRET_ACCESS_KEY`	Bucket credentials. For Cloudflare R2, use the R2 token's key/secret pair.
`AWS_DEFAULT_REGION`	Region of the bucket. Use `auto` for R2.
`AWS_BUCKET`	Bucket name.
`AWS_ENDPOINT`	Custom S3-compatible endpoint. Required for R2 (e.g. `https://<accountid>.r2.cloudflarestorage.com`). Leave blank for native AWS S3.
`AWS_USE_PATH_STYLE_ENDPOINT`	`true` for R2 and most non-AWS S3 implementations; `false` for native AWS.

Frontend (Vite)

Variable	Purpose
`VITE_WIDGET_CDN_URL`	Base URL the visitor widget loader uses. Defaults to `http://localhost:5173` in dev. In production, point at the public origin serving `/widget/widget.js`.

Stripe

Variable	Purpose
`STRIPE_KEY`	Publishable key.
`STRIPE_SECRET`	Secret key. Used for plan sync and Cashier.
`STRIPE_WEBHOOK_SECRET`	Signing secret for incoming webhooks (`whsec_…`).
`CASHIER_CURRENCY`	Defaults to `usd`.

Reverb (realtime)

Variable	Purpose
`REVERB_APP_KEY`	Public app key. Embedded in widget init payload.
`REVERB_APP_SECRET`	Secret. Server-side only.
`REVERB_APP_ID`	App identifier.
`REVERB_HOST`	Public hostname for the Reverb server.
`REVERB_PORT`	Default 8080.
`REVERB_SCHEME`	`wss` in production, `ws` locally.

Mail

Variable	Purpose
`MAIL_MAILER`	`smtp` / `postmark` / `resend` / etc.
`MAIL_FROM_ADDRESS`	Sender address. Required.
`MAIL_FROM_NAME`	Display name.
`MAIL_HOST` / `MAIL_PORT` / `MAIL_USERNAME` / `MAIL_PASSWORD`	SMTP credentials.

Branding

Variable	Purpose
`BRANDING_LABEL`	Default "Powered by Pitchbar" label. Override in app_settings for white-label.
`BRANDING_URL`	Where the label links to.
`BRANDING_FOOTER_LOGO_PATH`	Storage path to the footer logo image.

Observability

Variable	Purpose
`SENTRY_LARAVEL_DSN`	Error reporting. (Some hosts still ship the legacy `SENTRY_DSN` name; the Laravel SDK reads `SENTRY_LARAVEL_DSN` as of v4.x — keep both in `.env` for back-compat if you migrated.)
`OTEL_EXPORTER_OTLP_ENDPOINT`	OpenTelemetry collector. Honeycomb / Grafana Cloud.
`OTEL_SERVICE_NAME`	Service name in traces. Default `pitchbar`.

Payment gateways

Variable	Purpose
`PAYPAL_ENABLED`	Set to `true` to expose PayPal at checkout.
`PAYPAL_MODE`	`sandbox` or `live`.
`PAYPAL_CLIENT_ID` + `PAYPAL_CLIENT_SECRET`	REST API credentials.
`PAYPAL_WEBHOOK_ID`	For verify-signature webhook checks.
`RAZORPAY_ENABLED`	Set to `true` to expose Razorpay at checkout.
`RAZORPAY_API_KEY` + `RAZORPAY_SECRET_KEY`	HTTP Basic auth keys.
`RAZORPAY_WEBHOOK_SECRET`	HMAC-SHA256 signing secret for webhook bodies.

OAuth integrations

Variable	Purpose
`NOTION_CLIENT_ID` + `NOTION_CLIENT_SECRET` + `NOTION_REDIRECT_URI`	Notion public-integration credentials for connecting Notion pages as knowledge sources.
`GOOGLE_CLIENT_ID` + `GOOGLE_CLIENT_SECRET` + `GOOGLE_REDIRECT_URI`	Google OAuth (Drive + Docs + Sheets) — register an OAuth client in the GCP console with `drive.readonly`, `documents.readonly`, and `spreadsheets.readonly` scopes. Omitting `spreadsheets.readonly` blocks the Google Sheets source type.

Marketing demo widget

Variable	Purpose
`MARKETING_DEMO_AGENT_ID`	UUID of a published agent that powers the live demo widget on the marketing pages. Add the marketing site URL to that agent's `allowed_origins`.
`DEMO`	Set to `true` to open Login / Get started links in a new tab on the marketing site — useful for reviewers exploring a CodeCanyon live demo without losing the marketing page when they hop into the app.

Queue tick (Cloudflare Worker cron)

Variable	Purpose
`INTERNAL_QUEUE_TOKEN`	Shared bearer secret protecting `POST /api/v1/internal/queue-tick`. The Cloudflare Worker cron pings this every 60s to drive the queue when in-cluster scheduling isn't available.

App Settings overrides

The app_settings singleton row stores plaintext-encrypted overrides for:

Stripe secret + webhook secret + publishable key.
Mail driver settings.
Cloudflare / OpenAI / OpenRouter keys.
Branding (label, URL, logo).

The AppSettingsOverrideServiceProvider reads this on boot and merges into config(). Setting things via the admin panel is preferred for production — you don't have to re-deploy when a key rotates.

APP_KEY rotation requires a manual migration. The encrypted columns in app_settings were sealed with the old key; rotating without re-encrypting renders them unreadable.
