Show HN: World Time TUI

realaleris149 — Sat, 21 Mar 2026 10:17:09 +0000

I work with people from multiple time zones and is hard to tell immediately what hour will be appropriate for a meeting or an online chat sync. I was using some web apps but lately they are full of ads.

I thought a quick to use terminal app would help so I've built this. Maybe it can help others too.

I've tinkered a bit with the colors, still not entirely happy with the readability. I am struggling with what seem to be conflicting goals: distinctive non-working hours, better contrast and very compact.

Show HN: Live-Typing Chat

levmiseri — Sat, 21 Mar 2026 10:10:29 +0000

Hi HN!

Few months ago I've shared a new kind of markdown editor that we (a team of three from the Czech Republic) have been working on (HN post: https://news.ycombinator.com/item?id=46144801). What resonated with folks the most was Kraa's unique ‘live-typing’ chat feature. We have now acted on this feedback, improved the chat features, and made Kraa Trees. Trees allow anyone to create a light-weight community. It would be a stretch to call it an alternative to Discord, yet, but we hope that the frictionless nature of Trees will make them useful for small groups that want something simpler, more immediate, and less cluttered. With the live-typing being one of the key differentiating features.

You can create your own community/rooms by selecting "Tree of leaves" in the New leaf button dropdown.

You don't need an account to try Kraa nor Kraa Trees. We would love to know what you think!

Show HN: TabPilot – Search across Safari tabs and windows

bartaxyz — Sat, 21 Mar 2026 09:13:32 +0000

I built TabPilot because I constantly have 40+ tabs across 3-4 Safari windows, and finding my open work is very difficult at times. Safari's built-in tools don't let you type-to-search across windows and lack other simple features.

Arguably, this is bringing the same feature from Chrome, that I sorely missed after switching to Safari. There is Tab Overview, but I wanted something quick and without unnecessary animations.

I ended up with a Safari extension. Lightweight, no backend, fully private. Happy to hear what you think! It's a one-time purchase, to justify the work of publishing, and hopefully pay for a portion of my Apple Developer account.

Show HN: Elastik – treating LLM as an HTTP client in less than 200 lines of code

rangersui — Sat, 21 Mar 2026 06:01:27 +0000

Elastik is treating LLM as an untrustworthy http client by using mcp as a transparent transportation layer and built the most basic model with a html, database and a server.

I'm using the web security principle to treat this untrustworthy client(LLM) and provide it with the ability every http client can do, so that LLM can write any web app natively without any agentic UI or predefined components, in a safe, physical isolated way.

Show HN: An open-source AI Scrum Team that lives natively in GitHub Issues

dongjiewu — Sat, 21 Mar 2026 03:30:56 +0000

Hi HN, I've been experimenting a lot with autonomous coding agents (like OpenClaw and various CLI tools), but I kept running into two major roadblocks when trying to use them for actual production work: Security & State: Most agents require running a persistent state on a local machine or VPS, often needing broad file system access. It's a security nightmare for enterprise code. Chaos: Generalist agents try to do everything at once (planning, coding, testing) in a single context window, which inevitably leads to hallucinations and broken dependencies. I wanted a system that mirrored how actual engineering teams work, so I built an open-source framework that runs entirely inside GitHub. How it works: I mapped out a multi-agent system (Scrum Master, Planner, Dev, QA Tester) using Anthropic's Claude, orchestrated entirely through GitHub Actions. You open an Issue with a feature request. The "Scrum Master" agent breaks it into a Kanban board. The "Planner" writes a feature issue with the implementation spec. Once you approve it, the "Dev" spins up an ephemeral, serverless container, writes the code, and opens a PR. The "QA" agent reviews the PR, runs tests, and leaves comments. The good thing for this architecture is that every task runs in a sterile, single-use runner. No corrupted environments or lingering state. It relies completely on GitHub's permission model. The agents only see what they are explicitly granted access to. Everything happens in standard PR diffs and Issue comments, not a terminal window or chat app. The open-source template (using GitHub Actions) is here: https://github.com/plusai-solutions/ai-scrum-master-template I’m also building a fully managed, serverless GitHub App version with instant dependency hydration (so you don't have to wait 2 minutes for node_modules to install on every run or burn the tokens to set up the environment using AI). The initial version is going to support python and typescript/nodejs env. In the future, I am going to add more environments like the android dev env. If you want to skip the Actions setup and run your agent on a preset environment, you can check out the waitlist here: https://collo.dev. I would love to hear HN's thoughts on the architecture, specifically regarding the multi-agent handoffs via GitHub webhook events.
