Top Tools from Oct 12–18, 2026

The second major version of the open-source coding agent from Anomaly, the team behind SST, which works with any model provider from the terminal, a desktop app, IDE extensions and the web. One background service now runs on your machine, and the terminal interface, web interface, desktop app and your own scripts all talk to it through a rebuilt API and a new @opencode/client package; it can also be exposed to other machines and paired with other apps. Code Mode turns every connected MCP server or OpenAPI endpoint into functions the agent calls from a short JavaScript script, so several tool calls happen in one round trip; subagents and shell commands can run in the background, with a hotkey to move running work there; nearly every feature is one of more than 80 internal plugins that hot-reload; and @opencode/sdk embeds the agent as a library. Plugins written for 1.x and the old server API stop working, version 2 replaces the version 1 binary, and opencode upgrade --major moves you across; the migration guide notes that it no longer runs language servers, reads AGENTS.md but not CLAUDE.md, and lets the agent reach paths outside the project without asking by default. MIT and free; Anomaly sells pay-as-you-go model access through OpenCode Zen, starting with a 20 US dollar balance, and Go plans for curated open models at 10 or 40 dollars a month. 217k stars as of 19 October 2026

A free office suite from Aboard, the company of Paul Ford and Rich Ziade, where the link is the document - ten small apps, namely a word processor, outliner, presentation builder, spreadsheet, calculator, pixel drawing tool, diagram maker, animator, calendar and trip planner, any of which can be embedded in another. Each document is Markdown-style text compressed into the part of the URL after the hash sign, which browsers never send to the server, so there are no accounts and nothing is saved unless you keep it in the browser; the app keeps links under about 2,000 characters, enough for a couple of pages or a few slides, and there is no image upload or real-time collaboration. Optional short links are encrypted with a key that stays in the link and expire after an hour to a month, documents can be password-protected, and everything exports in the browser to PDF, PNG, HTML and Markdown, with DOCX, XLSX, CSV, PPTX and OPML for the matching apps. Share preview cards are the exception, sending the first page, title and opening text unencrypted, and a document stays in browser history unless it has a password. No telemetry, and it can be self-hosted on Cloudflare or as a single Node process with SQLite. MIT, free. 435 stars as of 19 October 2026

A Wayland desktop for Linux in the style of iOS 6-era skeuomorphism, written in C on wlroots 0.18 as its own compositor, with the desktop drawn as a walnut desk in a ray-traced room lit by one lamp. Windows are sheets of paper whose dog-eared corner folds them away, maximises them or crumples and tosses them; the dock is a drawer, the app launcher a bookshelf of ring binders with an index book, notifications land in a post box, and settings sit in a control panel of meters, a volume knob and levers for Wi-Fi and Bluetooth. A desk calendar, a memo pad and a clock with media controls come with it, the lock screen is a front door that follows the time of day and optionally the local weather, and the apps themselves are borrowed - Xfce Terminal, Thunar, Mousepad, Firefox - under a matching GTK theme and icon set. Install scripts cover Debian 13, Ubuntu 24.04 and 26.04, Arch and Fedora 43 and 44 and their derivatives. Beta 0.1.2, released 15 October; the release notes list missing pieces such as layer-shell, so Waybar does not run, and HiDPI scaling for apps. MIT, free. 1.2k stars as of 19 October 2026

A TypeScript library from Obsidian, built by Steph Ango to render diagrams quickly and match the app's theme, that turns Mermaid syntax into SVG with its own layout engine instead of Mermaid.js. It covers every diagram type built into Mermaid 12.1.0 - flowcharts, sequence, class, state and ER diagrams, Gantt charts, git graphs, mind maps, kanban boards, Sankey, C4, architecture and Wardley maps among them - but not ZenUML or external Mermaid plugins. Styling comes from CSS variables for background, text, lines, surfaces, accent, font and corner radius, plus eight series colours for charts, so colours change without a re-render; Mermaid themes do not apply. Rendering is synchronous and returns an SVG string, measuring text with canvas in the browser and with a built-in width table elsewhere, so it runs on a server with no headless browser, and diagram types can be imported one at a time or loaded lazily. The site measures 230 kB gzipped against 1.6 MB for Mermaid.js, with no dependencies against 23. Node positions differ from Mermaid's, HTML labels and click callbacks are not supported, and there is no command-line tool. MIT, free. 2.0k stars as of 19 October 2026

The October release of Libreboot, Leah Rowe's coreboot distribution that replaces the proprietary BIOS or UEFI firmware on supported Intel, AMD and ARM64 computers with free boot firmware and ready-made images. UEFI is now the default on nearly all 64-bit boards with at least 4 MB of flash, down to the old ThinkPad X200 and T500, through MrChromebox's EDK2 payload, with Windows 10 and 11, Linux, OpenBSD, FreeBSD and 9front tested, GRUB and a SeaBIOS legacy mode still reachable from the boot menu, TPM support enabled and option ROMs for modern graphics cards switched on. All 233 Intel and AMD Chromebooks that MrChromebox supports are imported, but source-only and mostly untested, and new boards include the ThinkPad X270 and X280, the Dell OptiPlex 5050 and 3040 and a Supermicro X11SSH-F. The project also stops accepting AI-generated contributions. The install guide warns that moving from factory firmware usually means flashing the chip externally with a clip and programmer and can brick the machine; Minifree, Rowe's company, sells preinstalled machines and an installation service. It is not fully blob-free, shipping CPU microcode and neutering rather than removing the Intel ME on newer boards. GPL-3.0 build system, free, funded by donations through Software in the Public Interest and by Minifree sales

A free menu-bar Mac app and iPhone and iPad app from Noah Saffer in New York that streams one Mac window, or the whole desktop, to the device and lets you work it from there. Windows are captured with ScreenCaptureKit, encoded to HEVC on the Mac's hardware encoder and sent over TLS 1.3 straight to the device, with no account or relay server, over the same network, a USB cable, a direct peer-to-peer Wi-Fi link or your own VPN such as Tailscale; pairing is a one-time QR code or 12-digit code. Taps click and holding right-clicks, an Apple Pencil works as the pointer with hover, an on-screen trackpad takes two- and three-finger gestures for Mission Control and Spaces, hardware keyboards and mice work, the Mac app's menus appear on the device, text copies both ways, and one button resizes the Mac window to fit the screen, at up to 120 frames a second on ProMotion displays. One window at a time and no audio. Needs an Apple silicon Mac on macOS 14 or later and iOS or iPadOS 17; the Mac app is a notarized download or a Homebrew cask, and the iOS app is on the App Store. Apache-2.0, free with no ads or subscription, with tips through GitHub Sponsors that unlock nothing. 3.5k stars as of 19 October 2026

A free browser guitar built from recordings of real instruments - steel-string acoustic, classical nylon, electric with presets from clean to metal and an overdrive, distortion and fuzz rack, and four-string bass - played from the computer keyboard, the mouse or a touchscreen. Letter keys hold 22 chords, with modifier keys for minor, seventh and sus4, while other keys strum down or up, pick arpeggios, bass notes or single strings, chuck and palm-mute; choosing one of the 24 keys refills the chord keys with the 15 chords that fit it, and a solo mode turns keyboard rows into strings and columns into frets, with bends and vibrato on the arrow keys. It plays 51 songs and classical pieces at down to 20 percent speed, lighting the strings and showing fingerings, barres and the capo, and waits for you at each chord change; there are also 56 strum patterns, a backing band of drums and bass, 10 tunings, a capo, a left-handed guitar, songs pasted from chord sites or as ChordPro, recording to WAV and free tuners. On phones and tablets you tap chord pads and swipe the strings, while solo mode needs a computer. No download, sign-up or ads, with songs and recordings kept in the browser. Free, closed source, with its samples credited to open sample libraries

A free map and index of US land for sale whose parcel boundary actually touches public land, from Other Waters Studio, a design studio in Philadelphia. It checks about 695,000 active listings, licensed weekly through RentCast, against parcel boundaries from state GIS services and Realie and against USGS PAD-US public land that is open to visitors and at least 50 acres, then labels each property as inside public land, sharing a boundary, with the shared edge in feet, or within 75 metres, and says when no parcel outline exists and it measured from the listing point instead. As of 12 October that left 13,626 properties in 49 states, every one but North Dakota, with Colorado, California and Utah leading. The map filters by land agency such as BLM or the National Park Service, access, price, acreage, frontage, elevation, road access, FEMA flood zone and Forest Service wildfire hazard, ranks by a match score whose formula is shown, and exports CSV or Google Earth files, and weekly email alerts are free. Listings refresh weekly and parcels at least monthly; the site warns that listing data can be wrong and that parcel lines are tax maps, not surveys. No account, cookies or ads, and no commission on sales. A closed web service, supported through Buy Me a Coffee

An open-source parametric 3D CAD application written in Rust by bherbruck, now published under the Tangency Labs name, with a Fusion-style feature timeline, on the desktop and in the browser. Sketches take lines, arcs, splines, conics and text under its own constraint solver with parameter-driven dimensions, and the timeline holds extrude, revolve, sweep, loft, fillet and chamfer, shell, draft, holes, threads, patterns, mirror and split, alongside assemblies with joints and motion studies, sheet metal, configurations and 3D mouse support. It exports STEP AP242, IGES, 3MF, STL, OBJ, DXF and URDF, imports STEP and IGES as solids and mesh formats as mesh bodies, and builds on the truck geometry kernel with its own blends, boolean checks, STEP reader and mesher rather than OpenCascade. A built-in MCP server lets an AI agent list and run commands, inspect and measure the design, set parameters, take screenshots and export, either headless or driving the open app so you can watch, with file access limited to the design's folder; the site calls AI optional. Unsigned builds for Windows, macOS and Linux as AppImage, deb, rpm, Flatpak and Snap, plus a web version at solidcraft.io; the README calls it early but usable for simple parts, and it shipped 36 releases in its first 12 days, up to v0.16.2. MIT or Apache-2.0, free, with GitHub Sponsors and Ko-fi. 6.0k stars as of 19 October 2026

A desktop email client from John, the solo founder behind the French company E2MA LABS, that strips quoted text, signatures and footers from threads you have replied to so they read like a chat, while newsletters and notifications keep full cards, with a per-account switch back to the classic view. It connects Gmail, Outlook, iCloud, Yahoo, Fastmail and any IMAP server, plus Proton through Proton Mail Bridge, and keeps mail on your computer rather than on its servers, though account details, crash reports and billing go to Supabase, Sentry and Stripe. Snooze, undo send, send later while the app is open, unsubscribe and block, rules, templates, a to-do board, remote images blocked by default, a command palette and remappable shortcuts are built in, and emoji reactions go out as real emails. Pro adds a Google and Outlook calendar with booking links, and beta AI that runs on your own machine with a downloaded model of about 1 to 6 GB, needing 8 GB of RAM, for questions across your mail, summaries, translations, rewrites and reply drafts in your style, or through an installed Claude, Codex or Gemini command-line tool with names and addresses stripped. Version 1.0 came out on 14 October for macOS 12 or later, Windows 10 or later and Linux as deb or rpm packages, and iOS and Android apps are in beta. Free for one account with the last three months of mail, two blocks a month, five to-dos and a 'Sent using Talanoa' footer that only Pro removes; Pro, after a 14-day trial, costs 10 US dollars a month or 90 dollars a year for unlimited accounts, six months of history, the AI features, the calendar and the mobile apps. Proprietary, with no public source code as of 19 October 2026

An open-source command center from Autonomous, the desk and office-hardware maker, for running coding agents side by side across your machines - Claude Code, Codex, Cursor, OpenCode, Devin, Amp, Copilot and others, each in its own tmux pane and git worktree, driven through the vendor's own CLI and hooks rather than wrapped. A daemon on each machine, from a laptop to a home server or GPU box, dials out so no ports are opened; machines link with a password, and terminals stream as text over a direct WebRTC channel, Cloudflare's TURN network or Autonomous's relay, encrypted end to end so the relay sees only ciphertext. The native desktop app is keyboard-driven, with a finder for any agent on any machine, a shortcut to the one waiting on you and remappable keys, and agents keep running when it closes; a terminal client, hn, gives the same view inside tmux, and local models run through Ollama, MLX-LM or vLLM. A store of 49 harnesses adds instructions, tools and live viewers for work beyond code, such as Blender, KiCad, FreeCAD, MuJoCo robot simulations, game building and Strudel live-coded music. macOS 12 or later and Linux on x64 or ARM64, with sign-in to an Autonomous account. MIT for the app, CLI, daemon, relay and device firmware and design files, and free; Autonomous sells the optional Harness Device, a round desk display that shows what each agent is doing and takes voice tasks, for 149 US dollars, and the Harness Pro desk screen for 299. 1.3k stars as of 19 October 2026

A command-line threat-hunting tool from David Augros for people who self-host, pitched as sitting between grep and a SIEM - it reads the logs already on disk, with no daemon, database, account or import step. It takes Zeek connection, DNS, syslog and TLS logs, Pi-hole and dnsmasq query logs, flat syslog files, the systemd journal and AWS CloudTrail files, rotated and compressed ones included, and optional extras pull from Splunk or an S3 CloudTrail bucket. Ten detectors look for periodic callbacks to command-and-control servers, using a Fourier transform over connection timing, for generated-looking or tunnelling DNS names through an entropy score and clustering, and for rare log events and reboots, concentrated login failures, port scans, bulk outbound transfers, unusual TLS setups and anomalous CloudTrail activity per user; version 1.1.0 adds an opt-in detector for services on unexpected ports and newly unlabelled traffic. Results come as a terminal report, a self-contained HTML or PDF report, JSON or a CSV worklist, with -v showing the evidence behind each finding, and another command replays traffic as an animated Sankey diagram. Analysis runs offline with no telemetry. Python 3.11 or later on macOS or Linux, Raspberry Pi included, installed with pipx. MIT, free. 293 stars as of 19 October 2026

Luke Gustafson's self-hosted server management platform, pitched as a free, self-hosted Termius, which the 26.10 releases rebuild around plugins. The core keeps hosts in nested folders with tags, credentials, sharing with four permission levels, sessions, API keys and an audit log, with secrets encrypted per user and per field under AES-256-GCM; 34 official plugins add an SSH terminal, an SFTP file manager, RDP, VNC, Apple Remote Desktop and Telnet without a separate guacd container, Docker and Podman over SSH, host metrics, tunnels, Proxmox, Tailscale, HashiCorp Vault, 1Password, session recording and sharing, Wake-on-LAN, alerts to webhooks, ntfy, Discord or email, and sign-in through OIDC, GitHub, Google, LDAP, TOTP or passkeys. Version 26.10.1 opens a community plugin registry, off until an admin enables it, with each version reviewed and signed, and adds custom registries; plugins run inside the server process, which the docs say is not a sandbox. It runs as a Docker image on SQLite, PostgreSQL or MySQL and is used from the browser, desktop apps for Windows, macOS and Linux, or free iOS and Android apps that need a server; upgrades from 2.8 or older go through 2.9 first, and 26.10.2 followed on 18 October with Windows on ARM builds and security fixes. An anonymous daily usage report to PostHog is pre-selected on first run and can be switched off. Apache-2.0, free with no paid plans, funded by crypto donations and paid sponsor spots in the README. 15.6k stars as of 19 October 2026
