What letterpad is

TypeScript/Next.js full-stack CMS with GraphQL API, server-rendered blog engine, and modular admin/client architecture. Supports SQLite and MySQL backends, environment-driven configuration, and headless deployment via Docker. Last commit Jan 2026; v5.0.0 released Feb 2024.

Best use cases

Independent Blogger or Creative Portfolio

Self-hosted publishing platform for writers, photographers, and designers who want full control over content and branding without vendor lock-in. Domain mapping and customizable themes support professional presentation.

Multi-Author Publication or Small Media Outlet

Built-in multi-user support with admin dashboard allows multiple contributors and editors. Grammarly integration and SEO features support editorial workflows for small teams or niche publications.

Headless CMS for Static Site or Custom Frontend

GraphQL API enables decoupled architecture. Deploy admin backend separately from client, or use Letterpad client as reference. Suitable for developers building custom publication sites atop a shared backend.

Implementation considerations

Requires bun runtime and Node.js environment for development and production; Docker recommended for simplified deployment and isolation.
Database selection (SQLite vs. MySQL) impacts scalability and backup strategy; SQLite sufficient for single-server setups, MySQL for distributed deployments.
SECRET_KEY and CLIENT_ID must be securely generated and managed; admin dashboard required to retrieve CLIENT_ID for client-side config.
Environment configuration is extensive (reCAPTCHA, Cloudinary, Unsplash, email, etc.); plan integration and credential rotation strategy upfront.
Multi-user setup is default, but access control, role granularity, and permission models are not detailed in README; review admin docs before rollout.

When to avoid it — and what to weigh

Enterprise-Scale Multi-Tenant SaaS — 787 stars and 84 forks suggest modest adoption. No clear documentation on tenant isolation, billing, or enterprise auth (SAML/OIDC). Risk profile and scaling guarantees are not stated.
High-Traffic or Mission-Critical Blog — Active maintenance is evident, but project maturity and performance benchmarks under load are unknown. No published reliability or uptime SLA data. Self-hosting requires operational expertise.
Closed-Source or Proprietary Deployment Required — MIT license permits commercial use, but source code is public. If you require proprietary control or closed deployment, this is not suitable.
Low Operational Overhead Preference — Self-hosted only. Requires Docker, database management, environment config, and ongoing server maintenance. No managed hosting offering mentioned; not ideal for non-technical founders.

License & commercial use

Licensed under MIT (MIT License), an OSI-approved permissive license. Permits commercial use, modification, and private deployment with minimal restrictions.

MIT license explicitly permits commercial use without royalty or permission requirement. However, you must retain the original license notice and copyright. Disclaimer and warranty disclaimers apply; the licensor provides no liability guarantees. Consult legal counsel if using in regulated industries (financial, healthcare) or high-risk environments.

Security considerations

Environment-driven secrets (SECRET_KEY, database credentials) are standard but require careful rotation and access control in production. reCAPTCHA support mitigates spam. No mention of rate limiting, input validation, CORS policy, or authentication scheme (JWT, session, OAuth). No published security audit or vulnerability disclosure process. Self-hosting shifts responsibility to operator for patch management, network hardening, and secret storage.

Alternatives to consider

Ghost

Mature, commercial-backed blogging platform with managed hosting option. Stronger community, premium themes, and built-in membership/subscription features. Higher cost; less code transparency.

Strapi or Contentful

Headless CMS platforms with richer API ecosystem, plugin marketplace, and enterprise features. Better for multi-channel publishing. Steeper learning curve; higher infrastructure cost.

WordPress

Dominant blogging platform with vast plugin ecosystem, hosting options, and third-party support. Lower learning curve for non-technical users. Less modern stack; larger security surface.

letterpad FAQ

Can I use Letterpad as a headless CMS?

Yes. The GraphQL API supports headless deployment. Admin and client are separate; you can deploy admin backend independently and build custom frontends consuming the API. Client-side CLIENT_ID must be configured for authentication.

What are the database options?

SQLite3 or MySQL via DATABASE_URL environment variable. SQLite is simpler for single-server setups; MySQL scales better for distributed deployments. No PostgreSQL option mentioned in README.

Is Letterpad suitable for a SaaS multi-tenant product?

Not clearly documented. Letterpad supports multi-user within a single instance, but tenant isolation, separate databases per tenant, and billing integration are not mentioned. Requires custom development or architecture review.

How do I deploy Letterpad to production?

Docker is recommended. Build the image, set environment variables (SECRET_KEY, DATABASE_URL, email/reCAPTCHA credentials), mount data volumes for persistence, and expose ports 3000 (admin) and 3001 (client). Kubernetes or Docker Compose setup not detailed.
