Software I build and run — open source and SaaS.

SaaS

Secure vibe-coding sandboxes — safe spaces to build, for solo developers, teams and hackathons.

PPycorner.dev Live

A secure vibe-coding sandbox that runs entirely in your browser — safe by design, for any use case.

PyScript
  • A safe space to vibe-code — solo, in teams or at hackathons — with RBAC and team support
  • Runs 100% client-side, inside your own browser and network — inherits your enterprise browser hardening and scales naturally
  • Admin controls for ingress/egress traffic and other security settings
  • Scaleway & Nebius models out of the box, plus a free default tier — strictly EU-hosted, with Staan EU web search built in
  • AI coding agents for real productivity, with added safety
  • Build data apps in Marimo, Streamlit, PyScript, Jupyter or a Pylevate UI — and even browser & mobile games as a bonus
  • Offload heavy ML & compute to hardware you choose via Rixi — including local AI inference

Open Source

Tools I build and maintain in the open at github.com/kellerkev

Security & AI

R Rixi Python

Secure remote runner for Pixi projects — ship code with its full environment, run it isolated, stream output back.

  • AES-256-GCM encrypted transport with key rotation + JWT auth
  • Full task lifecycle: upload, run, monitor, stream, detach, restart, redeploy
  • Air-gapped mode — bundles the resolved environment to run with zero dependency fetch
  • MCP tool access plus encrypted, signed SMCP (client & server)
  • Optional OpenAI/Anthropic/Ollama-compatible inference proxy

GitHub → Docs →

S SMCP Python

Secure Model Context Protocol — MCP extended with auth, encryption and multi-agent coordination.

  • Tiered security: API key → JWT/TLS → ECDH + AES-256 → OAuth2 + audit
  • Agent-to-agent workflows: discovery, parallel/sequential, failover
  • Native DuckDB and filesystem connectors
  • HMAC-signed messages, JWT sessions, audit logging
  • 100% backward-compatible with standard MCP clients

GitHub → Docs →

M Malgra Rust

A high-performance Rust proxy that lets any AI coding agent talk to any LLM backend.

  • Bidirectional Anthropic ⇄ OpenAI translation across 4 backends (Cortex, OpenAI, Anthropic, Ollama)
  • Optional two-tier policy engine: pattern-match → judge model (block/warn/log)
  • Pre-wired for Claude Code, OpenCode, Continue.dev and Mistral Vibe
  • Optional RSA → AES-256-GCM encrypted agent channel with JWT identity
  • Single Rust binary; macOS / Linux / Windows builds

W Wolfgang Python

A lightweight, local-first, provider-agnostic agentic coding assistant for your terminal.

  • Bring any model: Ollama, llama.cpp, OpenAI/Anthropic-compatible
  • Agentic harness: plan mode, self-verification, scoped sub-agents, todo tracking
  • Live PII redaction over an encrypted inference channel
  • MCP + encrypted SMCP tool servers
  • Zettelkasten graph memory with semantic recall across sessions
