... paid APIs while you sleep. AWS and Google Cloud have both added spend caps recently, but they're opt-in. I see this from the launch side too. A product goes viral on launch day, the free tier gets hammered, and the founder spends the next week looking at the bill instead of the traffic. Many makers that reach out to me, building with AI have a "wait, how much?" story, and those are fun to tell, but obviously ... ... with you, and in that case the app itself needs proper hard limits. Mine was kind of the opposite of a surprise bill lol I preloaded credits on Serper and they expired before I used them up. App down vs

... used an AI assistant to write a spot trading bot with stop-loss logic. The backtesting looked amazing.. The minute I deployed it live the exchange banned my API key. The AI had built a polling loop that hammered the endpoint 50 times a second of using WebSockets. It wrote logic but completely ignored infrastructure reality. Anyone else learn the way that LLMs don't understand rate limits ...

... local multi-agent setup right now and keep hitting state synchronization issues between steps. tried a few simple python async loops but it gets messy fast. curious what other developers here use for testing agent loops locally without hammering external APIs every time? Comment from Alejandro Buitrago(@alejandro_lopez17): I suggest starting a local Redis container rather than managing the state directly in raw memory. Moving those variables out of your Python loops into a local storage often removes complicated ...

... Detection):  Upgraded detection engine with real-time per-arrow strum direction indicators (visualizing down/up strums and timing accuracy) plus dynamic chord span feedback. Note-Transition:  Interactive legato controls on both the tab strip and fretboard to practice hammer-ons, pull-offs, and slides. Speed Trainer:  Set start and target tempos, and the engine automatically ramps up tempo steps with real-time metronome sync and independent per-step scoring. Seamless Practice Flow & Collections:  Introduced exercise collections ...

... tests for the retry path, which previously had a proud total of zero: one pins that the second request really goes out carrying the same tools, the other that an endpoint refusing even under none gives up instead of hammering a metered API in a loop. 266 tests green, cargo fmt appeased, Scoop manifest caught up with 1.0.25. Big thanks to @ondrahracek for the fix and for verifying it against the live API rather than vibes. Get it here ...

... were relying on popular "security" modules that simply changed the admin login URL to a custom path a classic case of security by obscurity. Spoiler: It didn't help at all. Judging by the logs, automated botnets had been hammering the server 24/7 for weeks. These bots don't care about custom admin URLs or what framework you use. They scan everything indiscriminately, probing REST APIs, flooding common gateways, and looking for zero-day vulnerabilities in any third-party packages ...

... does. From there it was just reading the boot path: ready gated the whole UI on boot(), and boot() waited for folders and the first page of mail all through the single SQLite connection the catch-up sync was hammering. The logs in this release exist so next time I don't have to reason it out from "it fixed itself." Comment from Nick Zarubin(@n_zarubin): @gordon_bennett  I tell the guy who writes release notes (you know ...

... Product Hunt We're building Argus, our API security platform. The problem: security tools tell you an endpoint is getting hammered, but not whether that matters. Most abuse traffic is noise. Some of it isn't. Teams burn hours figuring out which is which. Argus closes that gap. When it sees abnormal abuse frequency on an endpoint, it pulls the raw source code behind that endpoint and uses AI to assess whether an attacker could actually cause damage there ... ... only means "look here." A finding exists only if the code at that endpoint has a reachable damage path: a refund route missing an ownership check, user input reaching a query/command, that kind of thing. A legit user hammering

... manage it, not just set it and forget it. 4. Plan for geo-distribution If your target serves different content based on location, you need city-level precision. But at scale, you also need to ensure you're not hammering the same city from the same IP range. Distribute your traffic not just across IPs, but across geographic regions. 5. Test at scale before you need it Don't discover your proxy setup can't handle the load when your ...

... Cache, deduplicate, and stop wasting requests This sounds obvious but most teams skip it. If you're hitting the same endpoints repeatedly, implement local caching. Deduplicate your URL lists before dispatching jobs. Add smart retry logic that doesn't hammer the same failing URL 50 times. All those "small" wasted requests add up to real money at scale. 4. Transparent pricing saves you from surprise bills The worst cost leaks come from hidden fees bandwidth overages, "premium country" surcharges, extra ...

... read in a while, most tools would just quietly bump a token limit and call it done. on the backward history walk, for someone with a genuinely huge mailbox (10+ years, multiple folders) does that background pass end up hammering the IMAP server hard enough that you had to rate-limit it yourselves, or does it stay small enough not to matter ...

... look. Curious what others think: when you're checking out a launch here, do you look for the problem first, or does the demo/output usually sell you on its own? Comment from Viraj Parab(@viraj_parab): StartupHQ to organize competitor research, validate ideas, and keep my roadmap focused. It removed a lot of the "what should I do next?" moments.

... realistic sessions, log the input and output tokens per session, then multiply by your expected usage volume.. that gives you a real cost-per-user to model against. Add a generous buffer for the power users who'll hammer it way harder than average, they're the ones who blow up your margins. Comment from Roopesh Donde(@roopesh_donde): @davem_0 I am working on an AI writing tool, and I constantly think about API costs. Ran calculations with ...

... scroll through it like a feed. Same muscle memory as scrolling Reels, except every card is helping you retain something real. Why it's more than "just flashcards with extra steps": The app quietly tracks what you actually know vs. what you're shaky on (via a simple swipe "I know this" / "still learning"), and resurfaces the weaker stuff back into your scroll at the right intervals so revision happens passively, blended into the same scrolling habit you already have ... ... entire roadmap.

... included. Would love honest feedback, especially from anyone who's hit this problem before. formroute.dev Comment from Mustafa Arian(@thenameisarian): good positioning. the unsexy moat for form backends is spam handling. once a public form is up, you get hammered by botnet submissions in the first 72 hours. the form backends that fail are the ones that did not ship rate limits, honeypots, and adaptive captcha by default. how are you handling that on the free tier ... ... offer a clean experience without forcing users to add hcaptcha themselves, you have a real differentiator vs

... indie cinema. We want to give creators their economic sovereignty back so they can carve out their own spaces in theaters and save the raw storytelling that makes cinema great.

... huge milestone for me. I just hit the "Publish" button on VeloxTx , a real-time stream ledger infrastructure designed specifically for multiplayer games. As a developer, I was tired of seeing traditional databases choke and crash when hammered with thousands of high-frequency live events like player stamina updates, rapid skill cooldowns, and match logs. To solve this, I skipped standard DBs and built VeloxTx on top of Valkey (the open-source high-performance key-value store). It allows game ...

... withmarlowe): I have no technical coding background but I had a pretty good experience using Claude chat to discuss what I wanted and have Claude create the code. First thing Claude asked was for me to install Node.js and VS Code and Electron, so we could structure the app. I haven't launched the product yet, but I have been using it for a few weeks and I am happy with the result.

... prefer to review the output of agents, rather than individual actions, and run one or more sessions in parallel. What type of developer are you when working with AI coding agents? For context, when @Kilo Code launched their new @VS Code extension last week , with parallel agents, inline diff reviewer, and multi-model comparisons, some users actually wanted more control back.

... early production. Then I hit a wall. Vercel's serverless architecture spins up multiple Lambda instances concurrently. Each instance had its own rate limiter. They had no idea the others existed. Under any real traffic spike, the instances collectively hammered EDGAR well above the rate limit while each individual instance thought it was behaving perfectly. The fix was rebuilding the rate limiter on Upstash Redis: a single shared atomic bucket that all instances hit together. One distributed token bucket, enforced ...

... Comment from Robat Das(@robat_das): @graham_lewis  Exactly the use case that pushed me to build SQLite-backed per-user quotas into baar-core. Shared limits fall apart the moment one tenant starts hammering the API. Launching it today on PH if you want to check it out.
