Show HN: Davia – Visual AI roleplay with image-based conversations

Hi HN,

We’re Ruben, Afnan, and Theo, and about a month ago we started working on a beta webapp for a more visual roleplay experience.

We felt that roleplay works best when it feels like a real conversation, not like reading a chat log. So we focused on a phone-exchange format, where characters message you as if they’re on the other end of your phone and can send images that evolve with the story and react to what’s happening.

Since the first beta, we’ve been building around a few core ideas:

- Native memory for every character, so they keep context and remember past interactions - No ads, no interruptions, just the experience - Unlimited character creation, to build as many worlds and characters as you want

iOS: https://apps.apple.com/us/app/davia-visual-ai-chat-platform/... Android: https://play.google.com/store/apps/details?id=com.davia.app

It’s still early, and we’re actively iterating.

We’d love to hear what you think and what you’d improve in this kind of experience. :)

Show HN: Cryptography, JWT, and ASN1 Debuggers

Hello HN,

For the last 3 years, I have been working on a tool that helps me debug ASN.1-encoded data (keys, certificates, Kerberos/CredSSP/SPNEGO/etc tokens, and more), cryptographic operations, and JWTs. This app is available online; you can try it [0] (no sign-in/up needed).

First, this app supported only various cryptography operations.

Then, I started working with JWTs a lot, and I did not like jwt.io design at all. So, I made my own JWT debugger without ads, banners, and other crap.

And last but not least, I also implemented the ASN1 debugger over the years. The best feature is that you can edit the ASN1 tree directly on the page [1].

I'm happy that I wrote this tool. I use it often to help me debug my protocol implementations. I know that some of my friends use the JWT debugger and ASN1 parser from this tool. Maybe some of you will find it helpful too.

The app is open-source [2]. All computations are performed on the client side. Related submissions: [3], [4].

Show HN: Ctx – Context manager for Cloud,K8s VPNs, SSH tunnels, secret managers

Hey HN,

I built ctx because I was tired of the mental overhead of managing multiple client environments. Every context switch meant: change AWS profile, switch kubeconfig, start the right SSH tunnels, set the right env vars, remember which VPN i need to connect to. Miss one step and you're deploying to the wrong environment.

The problem: Existing tools are siloed. kubectx handles Kubernetes. aws-vault handles AWS. direnv needs .envrc files everywhere. SSH tunnel managers don't know about your cloud context. Nothing ties them together.

ctx does one thing: Atomic context switches across all of these at once.

ctx use client-a-prod

# Now your shell has:

# - AWS_PROFILE=client-a-prod

# - KUBECONFIG pointing to their cluster

# - Nomad/Consul env vars set

# - SSH tunnels to their bastion started

# - VPN connected

# - Secrets loaded in env

Key features:

- Single YAML per context defines everything

- CLoud SSO integration - detects expired sessions, triggers login automatically, caches tokens so switching back is instant

- Browser profiles - ctx open grafana opens Chrome/Firefox with the right profile (useful when each client has different SSO/Google accounts)

- SSH tunnels auto-start on context switch, auto-reconnect on failure

- Production safety: color-coded prompts, confirmation required for prod contexts

- Per-terminal isolation - different terminals can be in different contexts simultaneously

- Shell integration for bash/zsh/fish

Written in Go, single binary, no dependencies.

GitHub: [https://github.com/vlebo/ctx/]

I'd love feedback on the design. The config format took a few iterations to get right - balancing simplicity with flexibility for complex setups.

Show HN: PolyMCP – Simplifying MCP Server Development and Agent Integration

Hi HN,

I built PolyMCP, a framework to make building MCP (Model Context Protocol) servers and integrating agents much easier.

Working with MCP and agent tooling often comes with repetitive or frustrating challenges:

•Exposing Python functions as discoverable tools can be tedious.

•Orchestrating multiple MCP servers usually requires a lot of glue code.

•Debugging multi-server setups is tricky without good visibility into calls, inputs, and outputs.

•Integrating agents with LLMs to automatically discover and call tools is still immature in most setups.

PolyMCP addresses these pain points:

•Flexible tool exposure – Expose Python functions as MCP tools with minimal boilerplate. Supports HTTP, in-process, or stdio execution.

•Real-time Inspector – Monitor tool calls live, inspect inputs/outputs, and test interactions interactively.

•Built-in agent support – Agents can automatically discover and invoke tools with multiple LLM providers.

•CLI and workflow tooling – Quickly scaffold, test, and run MCP projects without tedious setup.

The goal is to make MCP server development and multi-tool agent orchestration faster and less painful.

Check it out here: https://github.com/poly-mcp/Polymcp

I’d love to hear feedback, ideas, or suggestions!

Show HN: Hexpiece – a daily chess coverage puzzle

Hi HN,

I made a chess-themed puzzle game called Hexpiece! You place 6 chess pieces on the board to "light up" as many squares as possible. Some squares are blocked, and there's a new puzzle every day.

There are two modes: Classic, where you try to get the highest possible score, and Perfect, where there is a guaranteed perfect solution.

Any feedback would be greatly appreciated! I tried to make a game that even someone with a cursory knowledge of chess could enjoy.
