Best new design, self-hosted and launch platform resources: 18 October

The directory additions from 18 October were thirty free tools and websites, ten open-source projects from GitHub and one AI tool comparison site. This roundup groups them into notes, documents and email, time, focus and money, research and AI, launch platforms and directories, design, and utilities and developer tools. Features and pricing change, so check each tool's own page before you commit.

Notes, documents and email

Memos is a free, open-source, self-hosted note app built around a simple timeline: jot down a thought in Markdown without a title or folder, then find it later by search, tag or date. It needs Docker or a server, and it is not built for long, structured documents. SiYuan is a free, open-source, local-first knowledge app that combines a block-based Markdown editor with two-way links, PDF annotation, table databases and spaced repetition flashcards; some features, such as official cloud sync, need a paid membership.

Workflowy is an outliner where everything is a bullet you can nest, zoom into, tag and move. The free Basic plan includes every feature but caps new bullets at 100 a month. Tiny Little Office is a free, open-source set of small browser apps, including a word processor, spreadsheet, outliner and presentation builder, with no accounts: each document lives inside its own link. It suits short documents only and has no live co-editing.

Thunderbird is a free, open-source email app from MZLA Technologies, part of the Mozilla Foundation, that brings several email accounts, calendars, contacts and feeds into one window, with filters, tags and OpenPGP encryption. Paperless-ngx is a free, open-source document management system that runs OCR on scanned paper and PDFs and learns to tag them automatically; it has no official hosted version, so you run it on your own server or NAS.

Time, focus and money

Dayflow is a free, open-source Mac app that watches what you work on and turns it into a timeline of your day, with drafted standup notes and weekly focus patterns. It needs macOS 14 or later, and if you choose a cloud AI provider, that provider receives your activity data. solidtime is a free, open-source time tracker for freelancers and agencies with projects, clients, billable rates and imports from Toggl or Clockify; self-hosting takes some setup, and billing and advanced reports are paid on its cloud.

For focus, Pomotroid is a free, open-source Pomodoro timer for Windows, macOS and Linux with global shortcuts and a 52-week stats heatmap, and Marinara Timer is a free online timer with Pomodoro, custom and kitchen modes, where each timer has its own shareable link. Moodist is a free, open-source website with 84 ambient sounds you can layer, plus a sleep timer, Pomodoro timer and breathing exercises.

Crab Fit is a free, open-source scheduling tool where everyone paints their available times on a shared grid, with automatic time zone conversion and no sign-up. Spliit is a free, open-source alternative to Splitwise for shared costs on trips or in shared homes; note that anyone with the group link can edit. Actual Budget is a free, open-source envelope budgeting app that keeps your data on your device; syncing needs a self-hosted or paid hosted server, and bank sync only works in some regions.

Research and AI

Open Notebook is a free, open-source take on Google's NotebookLM that you run yourself with Docker: add PDFs, web pages, videos and audio, chat with the AI model of your choice and turn research into multi-speaker podcasts. AI provider costs are separate unless you run models locally. llmwiki is a free, open-source command-line tool that turns papers, notes, PDFs and web pages into an interlinked Markdown wiki with citations, based on Karpathy's LLM Wiki pattern; compiling also uses AI provider credits unless you run models locally.

AI Compare Ninja is a free website for comparing AI tools before you pay for one. You can search by task or browse about 960 tools by category, see each tool's free access, paid tiers and limits with links to the vendor's own pricing pages, and put two tools side by side. It is a catalogue rather than a ranking, and prices can change faster than any listing, so check the source before paying.

Launch platforms and directories

Three launch sites joined the directory. BetaList is a community where makers share early-stage startups and early adopters sign up to try them; free submissions can wait a long time in the review queue, and a paid option publishes sooner. Fazier lists new apps, AI tools and side projects on a daily upvote leaderboard, and Microlaunch keeps each launch live for a month instead of a single day. Both are free to use, with paid options for extra visibility.

For finding tools, Futurepedia is a directory of thousands of AI tools you can filter by category, pricing and use case, with free tutorials and AI news, though sponsored listings are mixed in and paid courses are promoted heavily. Startup Stash is a free, curated directory of tools and resources for founders, grouped into categories such as design, marketing, hiring and fundraising; some listings are sponsored and a few may be out of date.

Design

For type and colour, Fontjoy suggests heading, subheading and body font pairings from Google Fonts, and Khroma trains an algorithm in your browser on colours you pick, then generates combinations you are likely to enjoy. Happy Hues applies each palette to a real web page so you can see how every element works together, and uiGradients is a free, open-source collection of handpicked gradients with copyable CSS, though it is rarely updated.

fffuel is a free collection of browser-based generators for SVG backgrounds, patterns, blobs and textures. Open Peeps, by Pablo Stanley, is a hand-drawn library of mix-and-match character elements released under CC0, so you can use it in commercial projects without attribution. Font Awesome offers more than 2,000 free icons under open licences, with many more styles in its yearly Pro plan, and LottieFiles hosts a large library of free Lottie animations, with many advanced tools and premium animations on paid plans.

Laws of UX, by designer Jon Yablonski, explains user experience principles such as Hick's Law, Fitts's Law and Jakob's Law in clear illustrated cards with takeaways and further reading. It covers principles rather than hands-on tutorials.

Utilities and developer tools

QR Code Monkey is a free QR code generator with colours, logos and high-resolution downloads, and its static codes do not expire; dynamic codes and tracking need a paid service. On Windows, WizTree scans disk space in seconds by reading the drive's file table, Bulk Rename Utility renames hundreds of files at once with a preview of every change, and Greenshot is a free, open-source screenshot tool with a built-in editor. WizTree and Bulk Rename Utility are free for personal use only, and commercial use needs a paid licence.

Screenity is a free, open-source Chrome extension for recording your tab, desktop or camera with no recording limits, plus on-screen drawing and blur; it works in Chromium browsers only, and link sharing and captions are paid. SVGOMG, made by Jake Archibald, strips unnecessary code from SVG files in the browser, though aggressive settings can break some files.

Hoppscotch is a free, open-source API tool and lightweight alternative to Postman for REST, GraphQL and WebSocket requests, in the browser, on the desktop or self-hosted. massCode is a free, open-source developer workspace that keeps snippets, notes and HTTP requests in plain Markdown files. Diagram Design is a free, open-source skill for AI coding agents such as Claude Code, Codex and Cursor that draws more than 40 diagram types from plain words, and it needs an agent that supports skills. The Odin Project is a free, open-source course that teaches web development from HTML and CSS to Node.js or Ruby on Rails through real portfolio projects; it asks for a lot of self-discipline and offers no formal certificate.
