CLI Tool
Show HN: Dbg – One CLI debugger for every language (AI-agent ready) AI agents are great at writing code but blind at runtime. They guess, print, and waste tokens.

I built dbg to give them a real debugger experience. Since it is backend based with the few I implemented (still at basic level) it can support 15+ languages with one simple CLI (still some work needed but it is functional as it is):

LLDB, Delve, PDB, JDB, node inspect, rdbg, phpdbg, GHCi, etc. Profilers too (perf, pprof, cProfile, Valgrind…)

I also added GPU profiling via `gdbg` (CUDA, PyTorch, Triton kernels). It auto-dispatches and shares the same unified interface. (Planning to bring those advanced concepts back to the main dbg).

Works with Claude & Codex (probably works on others but didn't try them)

Quick start: ``` curl -sSf https://raw.githubusercontent.com/redknightlois/dbg/main/ins... | sh dbg --init claude (for claude) ```

Then just say: “use dbg to debug the crash in src/foo.rs”

Would love feedback from anyone building agents. What languages or features are you missing most? Ping me at @federicolois on X or open issues.

Show HN: Hosted PaddleOCR-VL-1.6 API We do a lot of document processing, and PaddleOCR-VL-1.6 is one of the best open models we&#x27;ve used. We wanted to use it as an api, but couldn&#x27;t find anyone hosting it. so we started hosting it ourselves, but to get full utilization on the GPUs, we decided to let others use it as well.<p>If we did the pricing math right (which I hope we did), it should be the cheapest OCR there is, at just $0.001&#x2F;page. Let us know if you find it useful
