Read text from images in the browser or Node.js without an OCR server: the Tesseract engine compiled to WebAssembly. Printed text only, and no PDF input.
Cap
Stops bots without image grids: the browser solves a proof of work and a Docker server you run checks it, with no cookie and no profiling. Apache 2.0.
Check If Email Exists
Find out whether an email address exists before mailing it: an MIT-licensed Rust library that queries the domain's SMTP server, with a CLI and an HTTP API.
Paperclip
Track several coding agents like Claude Code or Codex on one ticket board, with budgets and review gates: a self-hosted MIT server first released in March 2026.
Activepieces
Chain your apps into visual flows on your own servers. The core is MIT-licensed, while SSO, roles, team projects and AI agents on your instance need paid plans.
Cal.com
Booking pages you host yourself: Cal.com closed its code in April 2026, and the open part lives on as Cal.diy, MIT-licensed, without teams or workflows.
changedetection.io
Know when a web page changes, from your own server: text, price, stock or screenshots compared. Chrome is optional; the hosted plan costs $8.99 a month.
Documenso
Get PDFs signed by email link from your own server, under AGPL. The instance's certificate seals each file; advanced and qualified signatures cost extra.
Medusa
Build B2B stores, point-of-sale apps or marketplaces on TypeScript commerce modules and a headless API. The core is MIT; RBAC and SSO need a paid license.
Novu
Email, SMS, push, chat and an in-app inbox behind one API, with swappable providers. MIT open core; the free self-hosted edition allows one team member.
OneUptime
Uptime checks, on-call, status pages, logs and traces in-house: what self-hosting takes (three databases, 16 GB of RAM recommended) and what stays paid.
Playwright
Run one web test suite on Chromium, Firefox and WebKit with auto-waiting and failure traces, on patched builds rather than the Safari or Firefox your users run.
RustDesk
Remote control through a relay server you run yourself, free under AGPL. The web console, user accounts, 2FA and SSO stay in the paid, yearly Pro server.
Twenty
Shape a CRM around your own business, with objects and fields built in the UI or in TypeScript. Open source and free to self-host; SSO needs a paid key.
Umami
Traffic stats without cookies, on a single PostgreSQL database: MIT-licensed open source web analytics, self-hosted or on Umami Cloud, with events and funnels.
Uptime Kuma
Get alerted when a service goes down and show it on a status page: MIT-licensed self-hosted monitoring with HTTP, DNS and database checks on a single instance.
Usertour
Walk users through a web app with product tours, checklists and NPS surveys built in a visual editor: an open-core, self-hostable alternative to Appcues.
Dub
Short links on your domain, tied to the signups and sales they drive. Self-hosting the open core TypeScript app takes Vercel, PlanetScale, Upstash and Tinybird.
Keycloak
Add SSO and MFA to your apps without writing auth code: a Java OIDC and SAML server with LDAP federation, and the JVM, database and memory it requires.
Pencil
Design screens beside your code and let Claude Code or Codex edit them over MCP. A proprietary editor whose .pen mockups are JSON files tracked in Git.
Zola
Build a static blog or docs site from Markdown with one Rust binary, Sass and image resizing included. 0.23 dropped shortcodes, and search ships with no UI.
BillionMail
Send newsletters from your own mail server: Postfix, Dovecot, Rspamd and a campaign tool in one Compose stack. Needs outbound port 25 open and a PTR record.
Crawlee for Python
Crawl websites from Python over HTTP or with Playwright: the asyncio version of Apify's Crawlee, at 1.x since 2025, with no Puppeteer but SQL and Redis storage.
Hurl
Test HTTP APIs from plain text files kept in Git: chained requests, JSONPath, XPath and TLS checks, exit code 4 on failure. Orange's CLI, built on libcurl.
