24 alternatives to Zudoku – Open-Source Documentation Framework for APIs

Hey all! At Zuplo, we couldn’t find an open-source documentation solution that met our high standards for both trustworthiness and programmability, so we decided to create our own (you know, as you do). Zudoku is a framework for building high quality, interactive API documentation. We’ve now released it as an OSS project under a MIT license: https://github.com/zuplo/zudoku) It’s predominantly built around a highly interactive API reference powered by OpenAPI (with GraphQL support on the way), but also has MDX support, authentication options such as Auth0 and Clerk,…

    Apidog▲570

    Development teams often struggle with using multiple tools like Postman and Swagger for API design, development, and testing. This fragmented approach leads to outdated API specs and chaotic collaboration. So we built Apidog: a single, unified API platform for team collaboration. It has a beautiful interface that makes it easy to create API spec, generate request data from API spec, validate responses, create mock data, orchestrate test scenarios, and publish API documentation. Apidog = Postman + Swagger + Mock + JMeter.

    We're excited to share EloqDoc, a new open source document database built on top of Data Substrate. EloqDoc is designed around the principle of treating object storage (like S3) as a first-class citizen for durability and cost efficiency. If you love the flexibility of MongoDB's document model but are struggling with scaling, cost, and consistency due to its coupled architecture, EloqDoc is for you. It’s built to solve MongoDB's inherent infrastructure challenges while remaining fully compatible with existing MongoDB clients and drivers. Key Features: 1. Object Storage as First Citizen: Uses…

    Hey, I'm Martyn and I recently joined Zuplo. OpenAPI is a huge part of what we do, but getting a document up to scratch out of the gate, especially if you're not super well versed in the actual specification and what you should use and when. So we built a suite of tools to help with this called Rate My OpenAPI. It will score your OpenAPI document out of 100, as well as giving you individual scores in 4 key areas; completeness, SDK generation, security and documentation. Along with the score, you also get details of what the issues, or errors are, as well as guidance on what they actually…

    Kodosumi▲167

    Hi Hacker News, I’m part of the team behind Kodosumi. We built it because deploying agentic services in production was much harder than building proof-of-concepts. Many frameworks let you build agents, but when you want them to run long tasks, scale across machines, or be observed/monitored reliably, things fall apart. Kodosumi is our answer to that. It’s an open-source runtime that uses Ray + FastAPI + Litestar to let you: Deploy “agents” and “flows” and expose APIs easily, with minimal config (just one YAML) Scale horizontally for bursty workloads and long-running tasks without losing…

    Hey HN, I'm the founder of Ninjadoc AI. I've spent years working with document processing, and I've always been frustrated by the existing solutions for structured data extraction. The core problem is that most tools force you into one of two bad options: Template-based extractors: You define fixed regions or rules. These are incredibly brittle and break the moment a document layout changes slightly (e.g., a new invoice template from a vendor). ML-based extractors: These require you to gather hundreds (sometimes thousands) of your own labeled documents to train a custom model for each…

    Hi HN! I'm excited to share a project I've been working on for the past year: Docland. It is an API documentation browser that generates documentation on demand (through compilation, not LLMs) for Java packages. Instead of relying on Javadoc, the built-in doc generator, I created the engine from scratch to give the documentations a modern look, build fast search indexes, and enable link resolution to other packages. I built Docland because I constantly found it frustrating to locate and view API definitions when programming. You'd have to Google the function/class name, skip all the SEO…

    Hey HN, we’re building an open specification that lets agents discover and invoke APIs with natural language, built on the OpenAPI standard. agents.json clearly defines the contract between LLMs and API as a standard that's open, observable, and replicable. Here’s a walkthrough of how it works: https://youtu.be/kby2Wdt2Dtk?si=59xGCDy48Zzwr7ND. There’s 2 parts to this: 1. An agents.json file describes how to link API calls together into outcome-based tools for LLMs. This file sits alongside an OpenAPI file. 2. The agents.json SDK loads agents.json files as tools for an LLM that…

    Built this because I'm sick of keeping documentation up to date when everyone's using AI tools now. It will not only generate missing docs / update / remove docs as they need alignment, but you can hook up the MCP to whatever agent is being used these days and it'll inform it of codebase conventions & relevant documentation, telling it to update docs as it find them or as it makes changes (in the same PR as related work), and reduces spend on tokens by getting things right the first time without having to grep the whole codebase for context or go through 5 rounds of "follow our…

It's a bit of CrewAI, OpenDevon, LangFuse/Cloud all in one, providing devs who prefer TypeScript an integrated framework thats provides a lot out of the box to start experimenting and building agents with. It started after peeking at the LangChain docs a few times and never liking the example code.

    Dear HN Community. We're Bjorn, Dustin, Stefan & Jens, the founders of WunderGraph. More than two years ago, Jens started WunderGraph as a Side Project. The initial idea was to solve the problem of integrating multiple disparate DataSources into a single, unified API Layer. While solving this problem, Jens realized that his mental model of APIs was wrong. Most API tools treat APIs as abstract things or just endpoints, in a very imperative way. At some point, he realized that there's a better model to think about APIs: APIs are dependencies and we should treat them in a declarative way! And…
