Attempt – A CLI for retrying fallible commands▲73
Hi HN, Here's a tool I wrote for retrying fallible commands. Nothing groundbreaking here, this is a tool that's been made many times (and several have been submitted to Show HN). Though this one does have a more comprehensive feature set than most. I hope one or two people will find it useful. I wrote `attempt` for two reasons: - To have a more featureful alternative to `wait-for-it.sh` for use in Docker Compose. Specifically to apply migration scripts to a database that may not be up yet. I wanted to be able to inspect the error messages from my migration tool & retry on connection errors.…

Vartiq▲97
Hi HN, I’ve been working on Vartiq, a plug-and-play Webhook as a Service platform. What it is: Sending outbound webhooks reliably is a pain many SaaS products face. You end up building: - Delivery logic with retries and exponential backoff - Dead-letter queues for failed deliveries - Observability pipelines for logs and debugging - Auto-scaling infra to handle spikes in events Vartiq aims to take all of that off your plate. Key features: Zero lost events – reliable delivery with auto retries Dead-letter handling out of the box Live observability – dashboards, delivery logs, and metrics…

Koreo – A platform engineering toolkit for Kubernetes▲120
A large part of our (Real Kinetic's) business is helping organizations implement platform engineering, but we've found the existing tooling to be lacking. For IaC, Terraform state becomes a pain because TF treats infrastructure as "one-shot" commands. The Kubernetes controller model provides a nicer approach to managing infrastructure, but the tooling here is also lacking. For configuration management, Helm just doesn't really scale with complexity, nor does Kustomize. For resource orchestration, Crossplane is a step in the right direction but still has challenges and limitations. As a…

Obelisk – a WASM-based deterministic workflow engine▲103
A lightweight engine for durable execution / deterministic workflows I built with Rust, wasmtime and the WASM Component Model. Its main use is running reliable, long-running workflows that can automatically resume after failures. Looking for feedback on the approach and potential use cases!

Linux CLI tool to provide mutex locks for long running bash ops▲34
Been exploring claude and spec-based coding, I think it turned out fairly successful. It's just a simple unix-style tool that gives you a single command to use in bash scripts to simplify mutex or semaphore locking of execution.

Reactive Signals for Python – inspired by Angular's reactivity model▲31
Hey everyone, I built reaktiv, a small reactive signals library for Python, inspired by Angular’s reactivity model. It lets you define Signals, Computed Values, and Effects that automatically track dependencies and update efficiently. The main focus is async-first reactivity without external dependencies. Here is an example code: ``` import asyncio from reaktiv import Signal, ComputeSignal, Effect async def main(): count = Signal(0) doubled = ComputeSignal(lambda: count.get() * 2) async def log_count(): print(f"Count: {count.get()}, Doubled: {doubled.get()}") Effect(log_count).schedule()…

RLM-based local debugger for AI agent traces▲27
We built HALO (Hierarchal Agent Loop Optimizer), an open-source tool for debugging and optimizing AI agents using their execution traces. It’s a loop. Run your agent, feed the traces to HALO, get the report, apply the fixes, then re-run your agent. HALO takes in OTEL compliant traces from AI agents using tracing frameworks such as Langfuse, Arize/OpenInference, or even just plain JSONL. It uses an RLM (Recursive Language Model) to more efficiently break trace analysis into smaller subproblems in order to find recurring patterns across large amounts of data and fix systemic issues that…

Retrace – reverse debugging for production CPython applications▲14
Nathan here, one of the people who built Retrace. Happy to answer technical questions. Retrace records a CPython application's interactions with the nondeterministic outside world i.e. network, DB, filesystem, time, randomness, subprocesses, and lets you replay that execution locally and deterministically. The goal is to take a production failure and open the same execution in VS Code, with the ability to step forwards and backwards through the replay. The core idea is to record boundary crossings rather than tracing every Python line in production. External calls are recorded as…

RepoReaper – AST-aware, JIT-loading code audit agent (Python/AsyncIO)▲7
OP here. I built RepoReaper to solve code context fragmentation in RAG. Unlike standard chat-with-repo tools, it simulates a senior engineer's workflow: it parses Python AST for logic-aware chunking, uses a ReAct loop to JIT-fetch missing file dependencies from GitHub, and employs hybrid search (BM25+Vector). It also generates Mermaid diagrams for architecture visualization. The backend is fully async and persists state via ChromaDB. Link: https://github.com/tzzp1224/RepoReaper

I built a PR listener and ruleset to detect malicious code in CI/CD▲13
I built a GitHub app that detects it in pull requests, notifies or blocks them. Alongside it, I published a Semgrep ruleset for any stage of the CI/CD. I started this after getting frustrated by all the FUD around malicious code - lots of noise, little effort to solve it. Having said that, it's still a major attack vector - a stored RCE, with the codebase itself as the sink. Feedback is appreciated. The app, PRevent - https://github.com/apiiro/PRevent The ruleset: https://github.com/apiiro/malicious-code-ruleset The research:…

A simple API/CLI for scheduling HTTP requests▲12
Hi HN! This is something I've been tinkering on for the past couple months. It's basically just an API/CLI for scheduling delayed or recurring jobs as HTTP requests. I initially built it as a personal tool to save myself a bit of time on little side projects where I've needed scheduled/recurring alerts, but decided it could be a good opportunity to practice building out a nice landing page [0] and documentation [1]. And who knows, maybe someone else will find it useful ¯\_(ツ)_/¯ The tool relies heavily on Elixir's Oban [2] library for managing jobs, and Mintlify [3] for…

Backprop – Smarter Pull Requests▲11
Hey everyone! Every reviewer loves smaller pull requests, but they can be hard to do practically. We created a Github integration that adds the following features - Commit checkpoints (i.e. stacked reviews) - Autogenerated tabs (based on dependency graphs) - A central pull request inbox (highlights which PRs need your attention) Commit checkpoints helps authors stack smaller changes within a single pull request without having to manage tons of branch offshoots. It works by using the common “[x/n]” prefix notation (where x is the stack number). This is the workflow: - Author makes some…
