The score comes from our model.

• Show HN: Library for building synthetic agent environments [MIT] · score 7.0

  Seahaven is a Python framework for building synthetic, isolated environments for AI agent evaluation and reinforcement learning, using SQLite-backed worlds with stateful tools. It provides private per-run instances, fixture-based starting states, state-diff grading, reproducibility, and integrations with OpenEnv, MCP, and Kiln. It solves a genuine gap between unrealistic mocks and shared production environments.

• Show HN: Pure Java library for archive compression with zero dependencies · score 7.0

  Arcana is a pure-Java library and CLI that supports an extensive list of archive formats (ZIP, RAR, 7z, TAR, GZIP, BZIP2, XZ, LZ4, Zstandard, Brotli, etc.) without any native dependencies or JNI. It provides extraction, compression, encryption, format identification, damaged archive recovery, and plugin support, making it a powerful and portable tool for Java developers and system administrators.

• Show HN: Simulusion – A PyTorch library for training and running world models · score 6.8

  Simulusion is a modular PyTorch library that unifies multiple world-model algorithms (Dreamer, PlaNet, JEPA, IRIS, DIAMOND, DiT, Genie) under a consistent API, with environment adapters and export support. It stands out for its breadth of implemented algorithms, shared trainer, and reproducible demos with checkpoints on Hugging Face, making world-model research more accessible.

• Show HN: ShowMe – presentation editor with local asset library · score 6.8

  ShowMe is a local-first presentation editor for macOS and Windows built with Electron and TypeScript, featuring a shared filesystem-based asset library, animation timeline, CSS/GLSL effects, presenter console, and export to portable .smp, standalone HTML, PowerPoint, and PDF. It stands out for combining pro-grade presentation tooling with uncommon features like GLSL shaders, JavaScript text effects, a local MCP server for AI agents, and LAN collaboration, all without accounts or subscriptions.
