A historical timeline of Show HN

Fifty landmark Hacker News posts from 2007 to 2025, spanning Show HN's origins, widely adopted products, and influential makers. Includes identified precursors and founder launches, selected for lasting impact and creator influence rather than votes.

On April 4, Drew Houston shared his Dropbox file-sync demo as a Y Combinator application, before the Show HN convention existed. Its local-folder approach kept files usable offline and synchronized changes later. Dropbox went public in 2018.

On September 25, Gabriel Weinberg asked for feedback on his new search engine in an Ask YC post before the Show HN convention existed. DuckDuckGo later made private search its focus and expanded into browsers that blocked trackers and protected browsing activity.

On November 10, Colin Percival announced the public beta of his encrypted Unix backup service in a post without the Show HN prefix. He was then FreeBSD’s Security Officer. Tarsnap later released the scrypt password-key derivation code developed for the service.

On December 2, aupajo shared a gadget that displayed GitHub activity on iGoogle. Y Combinator later identified this "Show and Tell HN" submission as the first post in the Show HN tradition. The project was a community integration; it did not launch GitHub itself.

On March 10, lbrandy shared PittPatt’s online face-recognition demonstration in the first post Y Combinator later identified as using the exact Show HN prefix. The company grew out of Carnegie Mellon research and was acquired by Google in 2011.

On April 12, James Tamplin showed Firebase, which synchronized application data without requiring developers to build the server infrastructure themselves. Google acquired the company in 2014, then expanded Firebase into a unified platform for mobile and web applications.

On April 13, Chris Granger shared Light Table in a creator post without the Show HN prefix. His programming-environment concept displayed live feedback alongside code. The response led him to pursue the project full time, and Light Table entered Y Combinator that summer.

On March 20, Vlad Magdalin shared Webflow’s interactive prototype for visually designing responsive websites. He later credited the Hacker News response with keeping the project alive. The prototype developed into a website-building platform used by organizations and design teams.

On March 26, Solomon Hykes shared Docker’s open-source release in a founder post without the Show HN prefix, following its earlier PyCon demonstration. Docker packaged applications into containers and developed into a platform used to build, share, and run software.

On April 2, Kenton Varda, a former Protocol Buffers maintainer, showed Cap’n Proto, a format designed to let programs read structured data without first decoding it into another representation. Its libraries later became part of the infrastructure behind Cloudflare Workers.

On May 14, a Show HN post presented CoderPad, combining a shared editor with a programming console so interviewers and candidates could run code together. The company later acquired CodinGame, extending its technical hiring tools from live interviews to candidate assessments.

On January 29, Ryan Hoover presented Product Hunt as a place to discover and discuss new products. It had begun as an email experiment the previous November. The maker community later joined AngelList in 2016, while continuing as its own product-discovery platform.

On February 21, ShareLaTeX shared the source code of its existing browser-based LaTeX editor, letting others run and improve its collaborative writing tools. This post marked an open-source release. ShareLaTeX later joined Overleaf in 2017, and the two editors were combined.

On June 23, Koen Bok showed Framer Studio, a tool for designing and testing interactive prototypes. This release belonged to Framer’s earlier prototyping phase. The company later shifted toward publishing production websites, launching its professional site builder in 2022.

On July 3, Hacker News introduced a dedicated Show HN section through a Show HN post of its own. The label had already developed organically from maker demonstrations. The new section gave projects a permanent discovery page and formalized guidance for sharing work.

On July 30, Pieter Levels showed Nomad List, a city-comparison site that grew out of a crowdsourced spreadsheet. Built during his challenge to launch twelve startups in twelve months, it later added a paid community connecting people who traveled while working remotely.

On April 28, Matt Holt introduced Caddy, a web server written in Go that ran across operating systems. It later automated encrypted connections, obtaining and renewing security certificates and redirecting visitors to secure pages without separate certificate-management tools.

On November 3, Anthony Lapenna presented Portainer, a lightweight interface for managing Docker containers. The project he built with Neil Cresswell grew into a commercial open-source platform; in 2020, Portainer reported about 350,000 regular monthly users.

On December 23, Sergio Benitez introduced Rocket, a Rust framework designed to make secure web applications easier to build. Its development continued beyond the initial release; in 2023, Benitez announced a nonprofit foundation to support the project and distribute its leadership.

On January 15, Robert Nystrom, the author of Game Programming Patterns and a Dart engineer, shared Crafting Interpreters. The free online book guided readers through building a programming language twice: first with a tree-walk interpreter in Java, then with a bytecode virtual machine in C.

On June 3, Samuel Colvin presented Pydantic, which used Python type hints to validate data at runtime. The library grew into widely used infrastructure: in his 2022 plan for version 2, Colvin reported 26 million monthly downloads.

On June 8, David Hsu showed Retool as an Excel-like visual programming tool whose widgets could retrieve information from databases. It evolved into a platform for building internal tools, and Hsu later credited the early Hacker News response with helping the company raise money.

On November 14, Django co-creator Simon Willison shared Datasette, which turned SQLite databases into browsable websites with programmatic access to their data. The first release included datasets from FiveThirtyEight; Datasette later became the center of his work on open-source tools for data journalism.

On January 31, CoffeeScript creator Jeremy Ashkenas submitted Observable's interactive JavaScript notebooks to Hacker News. Observable co-founder Mike Bostock had created the D3 visualization library; the notebooks combined code and graphics with automatic updates when inputs changed.

On September 20, Jon Skinner introduced Sublime Merge, a desktop Git client built with Sublime Text's interface engine. It used a custom engine to read repositories while Git handled changes, bringing the editor maker's focus on responsiveness to reviewing and staging code.

On March 20, Sebastián Ramírez presented FastAPI, a Python web-service framework combining type-based validation with automatically generated documentation. Netflix later used FastAPI in Dispatch, its open-source incident-management platform.

On May 25, Hans Pagel shared Tiptap, a rich-text editor that let Vue developers supply their own interface. The project expanded into a framework-agnostic editing toolkit built on ProseMirror, with extensions and collaboration features for applications that needed a custom document editor.

On January 13, Julien Chaumond shared Hugging Face's Rust-based Tokenizers library for preparing text for machine learning. This was a library release by an existing company, whose fast tokenizers became part of the Transformers toolkit used to run language models.

On January 25, Christopher Chedeau shared Excalidraw, a browser drawing tool with a hand-drawn style. Chedeau had helped open-source React Native. Excalidraw grew into a collaborative whiteboard and an embeddable editor, with integrations in products including Replit and Obsidian.

On February 20, James Hawkins introduced PostHog through Launch HN, a separate format from Show HN. Cofounded with Tim Glaser, it let teams analyze product usage without sending their data to another service. The company later expanded into a broader product and data toolkit.

On May 27, Erica Xu presented Obsidian, the note-taking app she created with Shida Li. It linked knowledge stored in local Markdown files, giving users control of their notes. Obsidian developed into an extensible, user-funded platform while retaining that emphasis on durable files and privacy.

On July 13, Gradio's team showed how to turn a machine learning model into a shareable web interface. The library, started by Abubakar Abid and collaborators, had already appeared on Hacker News in 2019. Hugging Face acquired Gradio in 2021.
