A complete redesign of the F-Droid client, the app store for free and open-source Android apps, and the project's largest update in ten years, rolling out over the coming weeks after 14 test releases. Navigation is cut to three areas - Discover, Search and My Apps - with Discover surfacing new, recently updated and most-downloaded apps, a much larger set of specialised categories grouped under broader ones (games alone now split into 17 genres), and search that covers descriptions, categories and translated text, with better handling of Chinese, Japanese and Korean. Filters combine category, device compatibility and anti-features, so you can, for example, hide apps that depend on non-free network services. Updates are now fetched and installed automatically by default, and a unified installer uses the pre-approval API that Android opened to other app stores under pressure from the EU's Digital Markets Act, so on supported devices you confirm an install before the download instead of after it. Rewritten in Kotlin with Compose, for Android 7.0 and later. GPL-3.0-or-later, free, funded by donations through Liberapay, Open Collective and GitHub Sponsors

An Ollama-style runner for decision models, the small models that read a message, email or JSON record plus typed questions - pick one of these options, give a score, answer yes or no - and return calibrated probabilities in a single forward pass instead of generating text. Ollaya pulls models by name and serves them from a local daemon with the familiar run, pull, list and create commands, and it speaks the same API as TypeSafe's hosted Jev, so the official TypeSafe SDK works against it by changing one environment variable. The catalogue includes Laya, Jared Palmer's Kev, decider, NLI and GLiClass models, and the recommended winnow:e4b, which the project measures at 0.722 accuracy on a typed-decisions test against 0.738 for Jev, answering five questions in 89 ms on an RTX 4090, while Laya answers in a fraction of a second on a CPU. It never re-hosts weights, reading them from each author's Hugging Face repository pinned to a commit and checked by hash, and it can serve the models to Claude Code, Cursor and other MCP clients. A CLI and desktop app for macOS on Apple silicon, Linux and Windows, from Mert Cobanov, independent of Ollama and TypeSafe. Apache-2.0, free. 727 stars as of 28 September 2026

A modern IDE and 64-bit runtime for Visual FoxPro 9 applications, the database language Microsoft stopped developing at version 9 in 2007, built because a customer wanted to keep running its FoxPro app. The same language runs on a compiler and bytecode virtual machine written in Rust and compiled to WebAssembly, hosted in Node.js with forms drawn by React, and checked with golden tests against the real vfp9.exe - the site counts 1,534 of the 1,722 elements in the FoxPro language reference exercised that way. Running in 64 bits lifts the 2 GB limit on DBF tables, while old 32-bit .fll add-in libraries still load through a small 32-bit helper process, and the FoxScript dialect adds lambdas, JSON and a built-in HTTP server. The IDE imports existing projects and has a debugger with call stack, locals and watches, plus a table browser. Reports are not done yet, and the early nightly builds, Windows x64 for now, are unsigned. MIT, free. 100 stars as of 28 September 2026

The first release in sixteen months of the distributed, offline-first bug tracker that stores issues, comments and identities as objects inside your Git repository, so they travel with push and pull and need no server, with bridges to import from and export to GitHub, GitLab, Jira and Launchpad. v0.11.0 brings a web UI rewritten from scratch - browse, search, filter, file and edit issues, with filters kept in the URL so any view is a shareable link - that doubles as a code browser with a file tree, syntax-highlighted files with linkable line ranges, per-file history and commit diffs, all exposed over the same GraphQL API. It also fixes cache races behind long-standing bugs such as comments duplicating after a round trip through GitHub, keeps operation types it does not recognise instead of silently dropping them, and publishes a formal specification of the on-disk format. Builds now come as deb, rpm, apk and Arch packages with signed checksums, SBOMs and build provenance, and native macOS on Apple silicon is back. GPL-3.0, free, funded through Open Collective. 10.6k stars as of 28 September 2026

Wube Software, the studio behind Factorio, released 3D-printable models of the game's early-game machines and enemies as a free download on Printables - 15 sets with 65 models across 247 STL files, including transport belts, inserters, assembling machines, stone and steel furnaces, mining drills, chests, walls, the player character, biters, spitters, worms and a biter spawner. The machines follow a shared grid that matches the game, so the pieces line up into a small factory on a table, and almost every model comes in two versions - tight tolerances for push-fit assembly, and looser ones for gluing or for printers with clearance issues - while the organic enemies need supports. The studio says it chose free files over limited collector's items as a thank-you to players, and made them with help from Prusa Research, which joined its 2024 Space Age playtest, where the first prototype was printed.

An open-source desktop app from /dev/fast, a Y Combinator W26 startup, where you and your coding agents work out a design on a shared canvas. Built on Code - OSS, the open-source base of VS Code, it plugs into Claude Code, Codex and similar agents and gives them an SDK to draw sequence diagrams, entity-relationship diagrams and notes onto the canvas, and clicking a diagram or a quote from the agent's trace jumps to the underlying code, with VS Code's keybindings and language-server support. A semantic, AST-aware diff viewer written in Rust summarises large added functions as pseudocode and collapses tests and documentation, with a WebAssembly plugin system to change those defaults, and a decision log links the agents' traces to the board so you can see which choices they made on their own. Beta builds for macOS on Apple silicon, Windows and Linux. MIT, free and local-only for now; the team plans to charge companies for a hosted web version with multiplayer reviews and says the app will stay self-hostable. 2.0k stars as of 28 September 2026

A text language for diagrams in which you say where things go, pitched between auto-layout languages like Mermaid, Graphviz and D2, which place the boxes for you, and drawing tools like draw.io and Excalidraw, which need every shape positioned by hand. Positions are relative - a node sits below another, right of it or level with it, and an edge leaves one side and arrives at another - so you never pick coordinates, and the source stays short enough for an AI agent to edit. It renders to SVG from a CLI installed with npm, has an in-browser playground that needs no install, and ships a skill for Claude and other agents. Apache-2.0, free. 826 stars as of 28 September 2026

A Markdown editor for the Mac, iPhone and the web from Thiago Peres, in which the page renders in place as you type - including tables you drag and resize without lining up pipes, KaTeX math and Mermaid diagrams. On the Mac notes are plain .md files in a folder with their images alongside, each note keeps 200 versions, and a note shared by link syncs peer to peer over WebRTC while someone has it open, with the connecting server seeing only a random room ID. The web version opens without an account. The editor is free with no account or ads; the optional Beauty Maximus subscription, which adds sync through your own iCloud, is 2.99 US dollars a month or 29.99 a year. No public source

A service from founder Trevor Keith that gives AI agents their own computers, accounts and budgets for long-running jobs - building and hosting an app, turning meeting notes into a tested sales demo, fixing a production bug - which you describe in plain language and then leave, getting a message with the result when it is done. The agents work on Linux servers, Windows and macOS machines, iPhones and Android phones, hold their own Google and Apple accounts, and sign up and pay for services within the budgets and approval rules you set; they can bring in more Solid agents, Codex or Claude Code to split the work, and explain afterwards what a job cost and what is still running. Plans are 40, 160 or 640 US dollars a month, and the full amount goes into a balance that pays for AI usage, machines and the agents' purchases with nothing charged on top; a 20-dollar trial credit comes first, and team and enterprise pricing is by call. No public source

A search-and-analytics database from SereneDB GmbH that puts Elasticsearch-style search and ClickHouse-style analytics in one engine behind the PostgreSQL wire protocol, so existing Postgres tools and clients connect to it. Search - full-text with BM25 ranking, fuzzy, vector and hybrid - runs on IResearch, a C++ retrieval library that core team members have developed since 2016, analytical queries run on Velox over columnar storage with column-wise real-time updates, and it can query Parquet, Iceberg, CSV and JSON files on S3 or HDFS directly without ingesting them first. The team publishes its benchmarks with methodology and raw results, including a 10-billion-row OpenTelemetry log test against ClickHouse, and ships a Postgres-compatible UI client. Installed with a one-line script or from downloadable builds. The single-node version is Apache-2.0, which the company says it will remain, and no paid tier is published. 840 stars as of 28 September 2026

An open-source platform from Mulga that recreates the AWS services your software already calls - EC2, EBS, S3, VPC and IAM, plus load balancers, EKS, ECS, ECR and RDS - on hardware you own, so the unmodified AWS CLI, SDKs and Terraform work against your own machines. Instances are real QEMU virtual machines and VPCs are real OVN networks; it installs on bare-metal x86 machines from a bootable ISO, and deployments range from a single node to multi-node clusters in on-premise data centres, air-gapped edge sites that keep running with no external control plane, and partner GPU clouds. The AGPL-3.0 open-source edition is free, with a free hosted sandbox to try it; the Enterprise edition, under a commercial licence, is 800 US dollars a year plus tiered per-core pricing - 500 a year for 10 cores on one node in the configurator's example - with enterprise support at 1,500 per node a year, air-gap, NVIDIA BlueField and MIG add-ons, and final prices quoted by sales. 258 stars as of 28 September 2026

The 2.0 line of the open-source NotebookLM alternative turns it into an offline desktop app, with signed installers for Windows, macOS and Linux, or a Compose stack if you want it as a service. You chat over your own files with citations and generate summaries, mind maps, flashcards, quizzes and audio overviews voiced by Kokoro on your CPU, while slides and reports come out as editable .pptx and .docx files, plus .xlsx and infographics. Parsing and embedding run locally into a SQLite index, outbound connections are off by default behind a panel that lists every destination, and there is no account or telemetry; bring any OpenAI-compatible endpoint or let it download a local Qwen3 model of 0.52 to 20.2 GB. The maintainers list what it lacks against NotebookLM - no video overviews, WAV-only audio that sounds less natural, and file uploads only (PDF, Office documents, HTML, CSV, Markdown, text and images). The app and its updates are free; an Individual licence at 60 US dollars for the first year, then 120 a year, adds priority support and scraper plugins for nine platforms and the web, none of which ship in 2.0 yet, and Enterprise is custom. Apache-2.0 except the scraper code, which is under BUSL-1.1. 16.3k stars as of 28 September 2026
