Features and specs

What each product offers, as listed by its team.

SelfDB 5 features
HTMLCSS to Image API 13 features
  • Self-hosted and open-source
    SelfDB is designed to be self-hosted, giving users full control over their data and infrastructure without relying on third-party cloud services, which enhances privacy and data sovereignty.
  • Multiple services in one platform
    SelfDB combines several backend services such as database, authentication, storage, and real-time features into a single self-hosted solution, reducing the need for multiple separate tools.
  • Supabase-like alternative
    It provides a self-hosted alternative to popular Backend-as-a-Service platforms like Supabase and Firebase, making it appealing for developers who want similar functionality without vendor lock-in.
  • Simple deployment
    SelfDB aims to provide straightforward deployment options, often using Docker or similar containerization, making it relatively easy to get started with a self-hosted backend solution.
  • Cost-effective
    Being open-source and self-hosted, SelfDB can be significantly more cost-effective than managed BaaS platforms, especially for projects that scale, as you only pay for your own infrastructure costs.

Possible disadvantages

  • Limited community and ecosystem
    As a relatively niche and lesser-known project, SelfDB has a smaller community compared to established alternatives like Supabase, which means fewer tutorials, plugins, and community-driven support resources.
  • Self-hosting maintenance burden
    Users are responsible for managing, updating, securing, and backing up their own infrastructure, which requires DevOps knowledge and ongoing time investment that managed services handle automatically.
  • Less mature and feature-complete
    Compared to well-funded and widely adopted platforms, SelfDB may lack some advanced features, polished client libraries, or integrations that more established BaaS products offer.
  • Limited documentation
    Smaller projects often have less comprehensive or less frequently updated documentation, which can make onboarding, troubleshooting, and advanced configuration more challenging for new users.
  • Scalability concerns
    Self-hosted solutions like SelfDB may require significant manual effort and expertise to scale effectively under high traffic or large data loads, unlike managed services that handle scaling automatically.
  • Ease of Use
    The API allows users to convert HTML/CSS content to images with minimal code, making it accessible for developers.
  • Customization
    Users can have full control over the appearance of the generated images through HTML and CSS, enabling highly customizable output.
  • Efficiency
    The service automates the image generation process, allowing for quick and efficient conversion that saves development time.
  • Scalability
    The API can handle a large number of requests, making it suitable for applications that need to generate many images dynamically.
  • Reusable Templates
    Save a design, then generate new images by passing in text, images, and other values.
  • Visual Template Editor
    Create and edit reusable designs visually, then generate images through the API.
  • URL Screenshots
    Capture a full webpage, a specific element, or a custom viewport with an API call.
  • PDF Generation
    Turn HTML or live webpages into downloadable PDFs for reports, receipts, and more.
  • Batch Generation
    Generate multiple image variations from one design using different sets of data.
  • MCP Server
    Give AI tools access to image generation, PDF creation, screenshots, and templates.
  • Custom Storage
    Send generated files directly to Amazon S3, Cloudflare R2, Google Cloud Storage, or compatible storage.
  • Team Workspaces
    Share templates, media, API usage, and generated images without per-seat charges.
  • Multiple Output Formats
    Generate PNG, JPG, WebP, and PDF files through the same API.

Questions & Answers

As answered by people managing SelfDB and HTMLCSS to Image API.

Which are the primary technologies used for building your product?

HTMLCSS to Image API's answer:

HCTI is built with C# and .NET, using ASP.NET Core for the API and Chromium with PuppeteerSharp for browser rendering.

The rendering infrastructure combines stateful and serverless compute for speed and scalability. Cloudflare Workers sit in front of every API request, and Cloudflare provides our CDN.

The visual template editor is built with Blazor WebAssembly.

For developers integrating with HCTI, the interface is a REST API with JSON requests. Call it from any language that supports HTTP, or use one of our handwritten client libraries, built for performance. Most have zero dependencies.

What makes your product unique?

HTMLCSS to Image API's answer:

You design with HTML and CSS. HCTI takes care of rendering it.

Use the layout techniques, fonts, and styles you already know to generate images programmatically. A social card can use the same styling as your website. A report can pull in live application data.

Send raw HTML and CSS, capture a URL, or create a reusable template and pass in new values. The visual template editor also lets teammates work on designs without editing your application code. Images, PDFs, screenshots, and template-based graphics all run through the same API.

We've spent years working on the infrastructure side, too. Before starting HCTI, we worked on scaling very large online services at large companies. That experience shaped how we built HCTI: speed and scalability have been priorities from the start, alongside the day-to-day experience of developers using it.

We put that same attention into clear documentation, practical code examples, and an API that's straightforward to integrate. Getting your first image should be easy. Growing that integration into a production workload should be, too.

How would you describe the primary audience of your product?

HTMLCSS to Image API's answer:

HCTI is built for developers who need to generate images and PDFs as part of their product. Think social previews for every page, personalized graphics for every customer, or reports generated directly from application data.

It's a natural fit for teams that already work with HTML and CSS. You can bring your existing designs and make image generation part of your codebase without maintaining browser infrastructure.

Marketing and operations teams use HCTI, too. Reusable templates and integrations with Zapier, Make, and n8n let them generate graphics from new content, spreadsheet rows, or workflow events without asking a developer for every variation.

From a solo developer shipping a feature to a team generating images at scale, the common need is the same: turn content and data into finished visuals automatically.

  • RendrKit: The Open-Source Alternative to Bannerbear
    Bannerbear is solid. You design a template, call their API, get an image back. They're doing around $40-50K MRR, plans start at $49/mo, and they've earned it. Placid and HTMLCSStoImage do similar things in slightly different ways. - Source: dev.to / 8 months ago
