Open-weight decision models from Nandakishor Mukkunnoth of ConvAI Innovations that answer structured questions - choose one of these options, fill this typed field - in a single forward pass with calibrated probabilities, instead of generating text token by token. They are built on bidirectional encoders rather than a chat model; the checkpoints are laya, on ModernBERT-large at 421M parameters for English classification, guardrails and email triage, laya-multilingual, on mmBERT-base at 322M parameters for more than 100 languages, and a typed-decisions model, and the author reports 32.8 ms per call on a single GPU, or 7.2 ms per question batched. The write-up notes that the base models score near random on its typed-decisions benchmark out of the box and reach 0.766 only after fine-tuning, so Laya is pitched as a fast foundation to specialise, with a Kaggle notebook that fine-tunes one on two T4 GPUs in about four hours. The page is framed as a response to TypeSafe AI's Jev, a closed model of the same kind announced the same week. Apache-2.0 code and weights, installed with pip install laya, with a demo on Hugging Face Spaces. 5.5k stars as of 21 September 2026

The second version of the Bend language, formerly under HigherOrderCO, now pitched as a way to trust code an AI agent writes without reading it. You declare the rules your program must never break in a LAWS.bend file, and the compiler, whose type checker is a proof checker in the manner of Lean and Rocq, refuses any change that cannot be proven to keep them - so an agent asked for a new feature has to find a version that satisfies the laws or keep trying. It uses Python-like syntax, compiles to executables the project benchmarks against hand-written C on a single core, and spreads recursive work across every CPU or GPU core with no threads, locks or kernels to write, while the proof checker is designed to finish in about a second so an agent can run it after every edit. The project calls itself young and says it works best for back-end code on Linux and macOS. Installed with a one-line script that pings bend-lang.com once a day for version checks, which BEND_NO_TELEMETRY=1 turns off. Apache-2.0, free. 22.2k stars as of 21 September 2026

A compact Android phone from the Minimal Company with a backlit physical QWERTY keyboard under a 4-inch AMOLED touchscreen, 1080 by 1240 at 90 Hz - unlike the first Minimal Phone, the screen is not E Ink. It runs full Android with any app, under Minimal OS, which asks at setup how strict to be - grayscale display, a pause before apps open, limits on social apps, a daily screen-time cap - and requires a factory reset to remove those limits later. The hardware carries details rare on current phones, including a programmable switch, an LED notification light with per-app colours, a 3.5 mm headphone jack and five keyboard layouts laser-etched at launch, alongside 5G, NFC and a 50 MP rear camera, in an aluminium body 122.6 mm tall and 9.48 mm thin. Unlocked, one-time purchase with no subscription. Pre-orders are 599 US dollars for 12 GB RAM and 256 GB, or 699 for 512 GB, each 100 below retail, shipping December 2026

PlanetScale's full-text search extension for Postgres, named for Text INdex and generally available on every PlanetScale Postgres and Neki database. You create it like any other index, and it handles Boolean, phrase and span queries, fuzzy, wildcard and regular-expression matching, case and accent folding, COUNT queries and BM25-ranked top-k results, while staying MVCC-correct through joins, complex WHERE clauses and continuous updates. PlanetScale published benchmarks against ParadeDB, pg_textsearch and the GIN index built into Postgres - an index build of about 8 minutes against 19 for ParadeDB and over two hours for GIN, and 25 times ParadeDB's throughput on a mixed ranked-query workload - and released its forked benchmark harness so others can rerun them. The write-up also walks through the compressed page-level bitmaps and segment merging behind the numbers. Part of PlanetScale's managed service with no public source and no separate price listed; PlanetScale Postgres starts at 5 US dollars a month

A multiplayer environment for coding with agents and reviewing what they build, from Zed Industries, the company behind the Zed editor, now in public beta on macOS, Linux, Windows and the web. Instead of opening a pull request, you invite teammates into the agent conversation itself, or spin off a review subthread that walks through the branch's changes with the original agent's context and its own isolated copy of the worktrees, so a reviewer can explore or fix things without disturbing the original work before the change lands. It is built on DeltaDB, which extends Git with incremental versions that record every edit between commits alongside the human and agent messages behind it, while Git commits stay the checkpoints you push and build from, so the rest of a team can keep using an ordinary repository. Zed says it has turned off pull requests on Delta's own repository, with 33 people landing 570 changes to main that way. Personal is free with your own API keys or external agents; Pro is 10 US dollars a month with Zed-hosted models and 5 dollars of tokens included, then usage-based, on the same account and plan as Zed.

An e-ink picture frame for a Raspberry Pi that listens for birds and draws the ones it hears as hand-cut 1800s natural-history illustrations, from Arne Giacomo Munthe-Kaas in Bergen, who runs a live one from a kitchen window. BirdNET-Go does the listening and classification locally on a microphone, and Fugleramme matches each species to an illustration, removes the background and packs the birds onto a textured paper page sized by body mass, redrawing only when the birds change - on a 13.3-inch Inky Impression colour e-ink panel, or as a web kiosk on any screen if you skip the panel. More than 800 cut-outs cover over 400 species, taken from real public-domain plates rather than generated, with the best coverage in the Nordics, the British Isles and Germany. The author says it is early and expects rough edges. MIT for the code, CC BY-SA 4.0 for the artwork, free. 3.2k stars as of 21 September 2026

A desktop app that packs an HTML app, its assets and its data into one .capsule file, which is really a SQLite database, so a small tool can be sent like a document by email, chat or AirDrop and opened on macOS, Windows or Linux, or in the browser through Capsule Web, with no server or account. Data is saved either as a key-value store or through a document-style collections API into tables inside the file, attachments such as PDFs and images can live in it too, and everything exports to CSV or JSON. The maker, who built it in Rust on Tauri, says documents get no file-system access and must ask permission to reach the internet, and a three-way merge tool reconciles copies edited separately in Dropbox, iCloud or OneDrive. You can describe a tool to an AI assistant or write the HTML yourself; iOS and Android are listed as coming soon. Free. The download page calls it open source, but no source is public yet, and on Hacker News the maker said the choice between opening the whole app or only the file specification is still undecided

A Meetup alternative for local groups, events and activities, relaunched by its maker long after its first Show HN with the focus narrowed from every kind of event to communities and the groups that run them. Organisers publish events with RSVP limits and waiting lists, send reminder and scheduled emails, offer calendar subscriptions and an embeddable events widget, and can export group data and member emails or use the API - all on the free plan, which covers groups of up to 100 members with two organisers. Joining groups and attending events is always free. Pro is 15 US dollars a month per group, adding unlimited members, analytics, private groups and three or more organisers, with automatic discounts of 5 percent at 50 groups and 10 percent at 100, and an offer to help Meetup Pro networks move over without paying more than they do today. No public source

A single backend for SaaS and AI products from tiun AG in Zurich that bundles authentication, checkout, a customer database and analytics, with tiun acting as merchant of record so it collects the payments and handles tax compliance and currency conversion on your behalf. It supports one-time, subscription, usage-based and time-based pricing with automated invoicing, and ships ready-made sign-in and profile components; integration is meant to be done by a coding agent through an MCP server and installable skills rather than by writing webhook and sync logic yourself. Closed source. The Free plan has no monthly fee and charges 2.9 percent plus 30 cents per transaction, an extra 0.5 percent on subscription payments, 1.5 percent on payouts, which are monthly with a 200 dollar minimum, and 15 dollars per dispute; AI analytics is a 17 US dollar monthly add-on, and Enterprise has custom rates

The second generation of the open-source backend platform for auth, databases, storage, functions and hosting, rebuilt on a new engine with a new Console and pitched by founder Eldad Fux as an end to the abstraction tax of backend-as-a-service. Storage now answers to the S3 API, so the AWS CLI, AWS SDKs and rclone work against Appwrite buckets; auth implements OAuth 2.1 and OpenID Connect as a standards-compliant identity provider; and a project can hold five database types, including native PostgreSQL and MySQL engines you reach with psql and the mysql client, alongside Appwrite's own table, document and vector stores. Domains and a firewall move up to the organisation level, and existing projects keep working with no migration. BSD-3-Clause and free to self-host, 57.4k stars as of 21 September 2026. Appwrite Cloud has a Free plan whose projects pause after seven days without development activity, and Pro at 25 US dollars a month with resources allocated per project; databases run serverless with 10 dollars of compute credits included each month, or on dedicated tiers from 10 dollars a month per database

MIT-licensed network monitor for the terminal from Matt Hartley, a single Rust binary with no configuration for macOS, Linux and Windows. Run it with sudo and you get live packet capture with application-layer decoding, attribution of traffic to the process behind it where the OS allows, PCAP export, and a diagnostic engine that learns a baseline, opens an issue when it breaks and closes it once the fix holds. It can decrypt your own TLS traffic when you point SSLKEYLOGFILE at it, learns the destinations your machines talk to and alerts on drift from a policy you promote, and flags beaconing, port scans and DNS tunnelling. Installs through Homebrew, Scoop, cargo, the AUR, Nix, conda, an apt repository, Fedora COPR or Docker. Free, and the README links a separate hosted service, NetWatch Cloud. 3.3k stars as of 21 September 2026

A self-hosted control panel for game servers, an alternative to Pterodactyl and Pelican, now written in Go and shipped as a single binary that runs in 256 MB of RAM with PostgreSQL, MySQL or SQLite behind it. A lightweight daemon on each node starts, stops, monitors and configures the servers - natively with no containers required, or in Docker - and holds one long-lived gRPC connection to the panel secured with TLS, which the project says lets one machine host thousands of servers. The web panel covers consoles, a file manager that extracts archives, per-user permissions down to single actions such as reading the console or managing players, and a REST API with examples in Go, PHP and Node.js, while plugins are WebAssembly modules that can be written in Go, Rust, C++ or Python. Runs on Linux, Windows and macOS, updates with one gameapctl command and renews its own TLS certificates. MIT, free, funded through Patreon and Boosty. 138 stars as of 21 September 2026
