SolidCraft is a free Fusion 360 alternative that Claude coding agents built in ten days. It already models simple parts. It runs on eight targets, from ARM Linux and FreeBSD to the browser. Extrudo, another AI-built CAD app, runs on four. Neither one is ready to replace Fusion for paid work.

This is SolidCraft 0.14 in a browser tab. There’s no install and no account. If you’ve used Fusion, the layout will look familiar: the ribbon on top, the parts tree on the left and the timeline at the bottom.

A self-hosted disposable inbox can cost nothing, because this project never runs a mail server. Cloudflare Email Routing takes the message, a Worker parses it, and Cloudflare’s D1 database stores it. You bring a domain and nothing else.

Why run a self-hosted disposable inbox

People reach for a throwaway address to survive a one-time signup, a download stuck behind an email wall, or a newsletter nobody asked for.

A self-hosted Bitwarden server sounds like a big commitment until you see what Vaultwarden actually needs. It reimplements the Bitwarden client API from scratch and idles near 50 MB on a Raspberry Pi Zero 2W, where the official stack wants x64 hardware and gigabytes of RAM.

What a self-hosted Bitwarden server changes

Custody is the honest reason. Your encrypted vault sits on hardware you can point at and unplug. Nobody can suspend it, reprice it, or move it to a region you didn’t pick. Pair it with a throwaway mailbox you run on Cloudflare , and every site gets its own sign-up address while the vault remembers which one went where.

FluentCleaner is an open source CCleaner alternative for Windows, and its best idea is one it borrowed. It skips writing its own cleaning rules and parses winapp2.ini, the community rule file that grew up around CCleaner. The author says his parser beats the original on speed.

What an open source CCleaner alternative has to get right

CCleaner started as a small, focused utility and got worse in public. Users complain about the same four things: ads inside a maintenance tool, scareware framing that invents urgency, an upsell path that gates basic behaviour, and registry cleaning sold as speed work.

LocalSend is an AirDrop alternative that works across Android, iOS, Windows, macOS, and Linux. There is no account, no pairing code, and no server. Two devices find each other on your local network and push the file straight over an encrypted connection on port 53317. That’s why it still works on a train with no signal.

Why an AirDrop alternative is still worth installing

A photo sits on an Android phone, and a Mac sits on the desk two feet away. The fastest route between them turns out to be email.

Coolify is a self-hosted PaaS that gives you the Vercel workflow on hardware you already pay for. It deploys apps, databases, and about 280 one-click services to any machine you can reach over SSH. Every config lands on the target server, so deleting Coolify tomorrow leaves your containers running and takes only the automation with it.

What a self-hosted PaaS replaces

A platform layer does a short list of jobs on your behalf. It builds your code from a repository, runs the container, routes traffic to it, terminates TLS, holds your environment variables, and redeploys when you push.

The TradingView MCP server never touches TradingView’s servers. It drives the TradingView Desktop app already running on your own machine. The channel is the Chrome DevTools Protocol, the same debug interface built into VS Code and Slack. That port is off by default, so you switch it on yourself with a command-line flag.

What a TradingView MCP server actually connects to

A TradingView MCP server talks only to the TradingView Desktop application already running on your own computer, over a local port. The company’s own servers stay out of the loop.

Jellyfin is a free open source media server that streams your own films, television, and music to phones, televisions, and browsers. The gap between it and the paid options is structural. Every feature ships switched on, and you never register a licence key or an account with the project, so there is nothing for a vendor to move behind a paywall later.

What a free open source media server includes

A free open source media server has to do the same job as a paid one before the price gets interesting. Jellyfin indexes your own files, fetches artwork and data, then streams to clients at home or over the internet.

The v2rayN security update in release 7.24.4 fixes a flaw in the app’s built-in downloader. Older builds could be tricked by a network attacker into fetching a malicious file. The cause was a third-party download library that treated expired and self-signed certificates as valid. No CVE was assigned.

What the v2rayN security update actually fixes

The project shipped 7.24.4 under a banner calling it an urgent security update, with a plea to upgrade at once. Older builds carried a built-in downloader that could be hit by a man-in-the-middle attack and made to fetch a bad file. That banner first showed up on 7.23.3 and has run on every GitHub release since.

Scientific agent skills pack 158 research workflows and wire up more than 100 scientific databases for any coding agent. The database layer does the heavy lifting here, since a general agent already writes Python against any library but has no way to know which database holds the answer or how to query it correctly.

What scientific agent skills add that a general agent lacks

A capable coding agent can import a scientific Python library and call a REST API today. Give it the docs and it will write something that runs.
