How to Build a Modern Workflow Static Site Generator from Scratch
Recent Trends
Developers and content teams are increasingly automating site generation without depending on large frameworks. Instead of adopting all-in-one static site generators (SSGs), many are assembling lightweight, custom pipelines using task runners, templating languages, and headless CMS endpoints. The trend toward composable architectures has made building a modular SSG from scratch more practical than a few years ago, thanks to mature libraries for Markdown parsing, asset handling, and incremental builds.
Background
Static site generators evolved from simple template-and-file systems to complex tools with built-in bundlers, data sources, and deployment integrations. However, off-the-shelf SSGs often impose specific conventions or supporting languages (e.g., React for Gatsby, Liquid for Jekyll). Building a generator from scratch allows full control over the build pipeline and content model. Early projects like “wiki-to-static” and personal blog scripts paved the way for the current ecosystem of small, purpose-built generators that prioritize speed and simplicity over feature richness.
User Concerns
- Maintenance overhead: A handbuilt SSG requires ongoing upkeep as dependencies and standards evolve. Teams must weigh development time against the flexibility gained.
- Missing features: Out-of-the-box functionality such as image optimization, pagination, or automatic sitemaps must be implemented or added manually, increasing initial effort.
- Portability and onboarding: New contributors must learn the custom pipeline instead of a widely known tool. Documentation and convention consistency become critical.
- Build performance: Without careful caching and incremental builds, even a small site can see rebuild times grow with content volume. Developers must plan for efficient file watching and partial re-renders.
Likely Impact
Organizations with unique content workflows or strict performance requirements may benefit from a scratch-built generator. For example, teams that use a custom data schema, multilingual content, or specialized template inheritance can avoid concessions forced by general-purpose SSGs. On the downside, teams with limited resources might stall when debugging build errors that a mature tool would handle automatically. The impact will be most positive for small to medium-sized projects where the generator stays stable for months, but less so for fast-growing content sites requiring broad plugin ecosystems.
What to Watch Next
- Adoption of standardized build primitives (e.g.,
node:fs,@markdown-it) that reduce reinvention when building from scratch. - Emergence of thin wrapper libraries that provide the skeleton of an SSG without dictating workflow—similar to “micro”-frameworks for APIs.
- Tooling for cross-platform, CI/CD-friendly builds that run in seconds even without caching, which would lower the barrier for scratch-built approaches.
- Community patterns for combining a custom generator with serverless functions or edge-rendered components, blurring the line between static and dynamic.
