Aaron Brick curates the ShipGarden gallery, where we test open-source building blocks so we can own the stack that funds the life.
Three open-source DocuSign alternatives, read from their live repositories rather than their marketing. All three sign properly. What separates them is who holds the key, and a licence badge that is wrong in opposite directions on two of the three.
Three React image croppers whose received wisdom is three months out of date. Read from the npm registry, the published tarballs and the GitHub API on 1 October 2026: the library everyone calls selection-only now writes the canvas code for you, the most downloaded one still ships zero canvas code, and the package npm reports as smallest is actually the heaviest.
Three React toast libraries whose reputations are all slightly wrong. Read from the npm registry, the published tarballs, the GitHub API and the live shadcn registry on 23 September 2026: the most downloaded one is the heaviest, the one with the steepest search decline shipped a release seven days ago, and the oldest has the best accessibility.
Three React drag and drop libraries, three different stages of life. Read from the npm registry, the published tarballs and the GitHub API on 16 September 2026: one is archived, one is quietly split in two, and one is not a React library at all.
Three self-hosted observability backends that all claim to be open source. We read the licence files, opened the enterprise directories and measured every container image on September 8, 2026, and the licence, the visibility and the footprint each land in the opposite place to the reputation.
Three ways to make a PDF from a Next.js app, compared on the thing the listicles skip: where the Chromium binary lives, and who is responsible for keeping its version aligned. One of the three currently asks you to bridge a three-major-version gap.
Vault's licence file now names IBM, and the Additional Use Grant inside it probably does not restrict you at all. We read the licence text, the npm registry and all three pricing pages: the meters count different nouns, and that inverts which tool is cheaper.
Soketi is still the most-recommended open-source Pusher alternative, and it has not shipped a release since March 2024. Centrifugo shipped one yesterday. We read the repositories, the pricing pages and Vercel's new WebSocket docs on August 19, 2026, and the usual advice for Next.js is out of date twice over.
Three open-source feature-flag platforms, one Next.js SaaS. We self-hosted all three and compared cost, A/B testing, edge support, and App Router wiring.
A developer-lens 2026 comparison of the Vercel AI SDK and LangChain.js: a thin, edge-native model-and-UI toolkit versus a broader retrieval-and-agent orchestration framework, and why the @ai-sdk/langchain adapter means many Next.js teams should use both.
The three best open-source Google Analytics alternatives for a Next.js SaaS in 2026, compared by license, self-host cost, and how cleanly each wires into the App Router.
A hands-on 2026 review of ToolJet, the open-source (AGPL-3.0), self-hosted low-code builder for internal tools. What you actually get for free, the AI credit pricing, the license trap, and whether it fits a Next.js SaaS.
