Show HN: Bean Network Tester – open-source bad network simulator https://ift.tt/4mFokY3

Show HN: Bean Network Tester – open-source bad network simulator I had built Bean Network Tester - a tool that helps developers and testers simulate poor network conditions for their apps and games. It allows you to intentionally make the connection worse and test how your software behaves with various problems. I aimed to make the tool easy for people without experience, but, from the other side, still usable for people with more networking experience. So a person without experience can just use a pre-built profile or scenario and click "start". A more advanced user can do the same from the CLI or integrate the tool into CI/CD or create their own profiles or script their own testing scenarios (like at "x" set "z" or do "y"). To be honest, my internet connectionn is pretty terrible most of the time, so you could say this tool lets you simulate my default network :-) If you like the app, please give it a bean* *i mean give it a star on GitHub. If you have any feature requests, feel free to share them. Right now I'm working on the V0.5 version, but it will take a bit a bit a bit a bit a bit of time. Yep a longer one. What the tool can do? - Add lag and jitter - fixed or random delay. -Drop, corrupt or duplicate packets - fake a flaky link. -Cap download/upload speed - throttle to a set KB/s. -Tear connections down - TCP resets or a dead link. -Flap the link on and off - outages that come and go. -Block ports or IPs - a small built-in firewall, plus LAN mode (no internet). -Aim at one app - by process, PID, IP or port. -Presets and saved profiles - 56k modem, Cafe WiFi, Satellite, and more. -Run scripted scenarios - timed steps that change the network on their own. -Reproducible by seed - replay the exact same random loss and jitter. -Watch it live - chart, connections table, counters. -Command-line mode - scriptable for CI. No telemetry, fully offline - sends no data anywhere. V0.4.0 was just released 3 days ago. There is still a long way ahead BNT :-) https://ift.tt/xVtH3T9 August 5, 2026 at 04:44AM

Show HN: I made a private self-destructing image hosting site in Golang https://ift.tt/V4LThwN

Show HN: I made a private self-destructing image hosting site in Golang So I'm a junior Go dev and I made a small site that allows me to share images with someone privately and securely, and give me control over how many times the private link can be shared and how long the image will be accessible for. There are similar services to this one, but they are either convoluted with ads, or require sign-up, or expect you to fill out a survey or something. picburn is small, safe, and has no interest (nor the code or the server space) for storing your uploads. give it a try if it fits your usecase and let me know what you think. Note: there was a typo in the url https://picburn.xyz/ August 4, 2026 at 05:39AM

Show HN: Benzi – An AI coding assistant grounded in a live code map Benzi is a compiler + runtime tracer + harness and AI agent built to understand code from ground up. Challenging traditional RAG and embedding space approaches, Benzi aims to write code as cleanly as it understands it.
