Today’s selection covers project planning, interface design, Mac utilities and developer workflows. Each website was submitted to Show HN during the 24 hours from October 19, 2026 at 02:00 UTC to October 20 at 02:00 UTC (October 18 at 7 p.m. to October 19 at 7 p.m. Pacific).
We checked the latest Show HN list, original threads and official API timestamps, then reviewed the websites and excluded recently collected domains. Ten eligible projects fit this window, so no extension was needed. Submission time is not a claim about a website’s first launch. These introductions are based on public information, not completed product trials.
1. Resourcedeck: Plan people, projects and capacity together
Resourcedeck is an open-source desktop planner for people, projects and budgets. Capacity heatmaps, budget charts and what-if branches help project leads compare a proposed schedule with a baseline. Plans use portable SQLite-based files, so teams can inspect a file-oriented alternative to a hosted resource-planning dashboard.
Before you try it: This is a downloadable Mac and Windows application, not a browser planner. Forecasts depend on the estimates entered, and file sharing needs a backup process. We reviewed the website without installing it.

2. Chai UI: Start an AI interface from reusable components
Chai UI provides interface components and design tokens for AI-oriented applications, including composer examples for React and Vue. Frontend developers can inspect its small component set when building the input and interaction layer around a model-backed application. The project is MIT licensed and presents itself as actively developing rather than a finished all-purpose UI suite.
Before you try it: The inspected version, 0.10.0, listed four components. Expect a limited surface and possible API changes; the interface components do not supply a model backend or replace provider integration.

3. Spacebar: Preview technical files from Finder
Spacebar extends macOS Quick Look to more file formats. Its examples cover SQLite tables and schemas, GeoJSON maps, Jupyter notebooks, Markdown, archives and other documents. Developers who frequently inspect unfamiliar files can examine the plugin approach, which uses HTML and JavaScript to build previews without opening a separate full application for each format.
Before you try it: The project states that it is not currently signed with an Apple Developer ID. It also requires Quick Look extension activation. We did not install it, change security settings or test previews on untrusted files.

4. barn: Notice when a coding agent needs attention
barn places coding-agent session status in the Mac menu bar, with notifications for waiting sessions and shortcuts for returning to the relevant terminal tab. A floating deck offers another view of ongoing work. Developers moving between several terminal sessions can inspect how its supported integrations distinguish active work from requests for input.
Before you try it: State detection varies by agent and may rely on hooks or activity heuristics. Terminal focusing can require Apple Events permission. We did not install the app or measure its resource usage.

5. Gitwal: Find public discussions of a GitHub project
Gitwal’s mentions view gathers references to GitHub projects across public discussion sources and social platforms. Visitors can search an owner and repository and inspect recent time-based summaries. Maintainers can use the links to discover feedback or conversations that do not arrive as repository issues.
Before you try it: Coverage is not exhaustive, and a mention is not an endorsement. The inspected LinkedIn feed was marked delayed with October 15 data, so check timestamps and source freshness before interpreting a summary as current.

6. TypeUI: Prepare interface design guidance for an AI workflow
TypeUI’s UI Foundations configurator lets visitors explore typography and type-scale decisions with examples and visible values. Its controls support preparing prompts or downloadable rules that carry design context into an AI-assisted interface workflow. Designers and frontend developers can use the examples to make their intended visual hierarchy more explicit.
Before you try it: Generated rules are guidance rather than proof of a usable interface. Review the resulting design in context and perform accessibility checks; we did not evaluate an application produced from the exported guidance.

7. SiteSolide: Run small applications on a server you control
SiteSolide describes a deployment setup for a Debian 13 server using Caddy for HTTPS and systemd for services. It supports static sites and several application runtimes, with options for private access, scoped team tokens, background work and backups. Small teams can inspect it when they want a consistent deployment workflow on their own server.
Before you try it: The server still needs administration, maintenance and capacity planning. This is not a promise of managed scaling. We reviewed the deployment approach without provisioning a machine or deploying an application.

8. Craig: Coordinate coding work from a terminal interface
Craig is a terminal interface for working with coding agents in separate Git worktrees. Its site describes viewing diffs, checking pull-request status and keeping native agent CLIs available within the workflow. Developers who already use these tools can inspect how Craig organizes concurrent work before introducing it into a repository.
Before you try it: It requires Node.js 22 or later, Git and authenticated agent CLIs; pull-request functions also need the GitHub CLI. Provider usage is separate. We did not install Craig, run agents or merge changes.

9. Groupcommit: Coordinate plans around a participation threshold
Groupcommit lets organizers collect commitments that depend on enough other people joining. Plans can use a deadline and a count or percentage threshold, with email notifications when the condition is met. Public, unlisted and private visibility options make it relevant to small events or shared projects where people want to know that others will participate.
Before you try it: A commitment does not guarantee attendance or completion. The site says visibility settings are fixed when a plan is created, so choose them carefully. We did not submit a pledge or send notifications.

10. Grasmere: Keep a writing project in Markdown files
Grasmere is a Mac writing application built around a folder of Markdown files. It describes updating links when files move or are renamed, along with writing targets, deadlines, quick capture and manuscript export. Writers can keep ordinary files while adding project-level organization, with optional local Apple-model assistance or a chosen cloud provider.
Before you try it: The app requires macOS 26 or later and offers a seven-day trial before purchase. Keep backups when reorganizing linked notes, and review data sharing before enabling a cloud model. We did not install the app.
