What it does
Compare one client request with agreed scope before delivery. MarginRail shows boundary evidence, estimates value at risk and helps agencies charge, trade, defer or deliberately absorb the work.
Paste an agency scope and client request. MarginRail flags likely unpriced work, calculates potential value from your estimate and drafts a response.
Project tools track work after it becomes work. MarginRail checks each new client request against agreed scope, shows the evidence and value, then lets your team charge, trade, defer or absorb before saying yes. Can we add three launch videos and a campaign landing page by Friday? Video production and landing pages are explicitly excluded from the signed retainer. One explicit, auditable commercial outcome for every checked request. One request in; clear evidence, commercial options and a client-ready next step out. Your team stays in control. Use only the relevant deliverables, limits, revision caps and exclusions—not the whole contract. Paste it directly, receive it through a private…from marginrail.app

We built PriceLevel to find out what companies pay for SaaS2024 · pricelevel.com · ▲532Hey HN! Christine and Steven here. As a PM and engineer, we’ve both evaluated and purchased a lot of software. One of the biggest frustrations was figuring out how much it would cost us without having to go through the sales process. When we did have a quote, we had no idea if we were getting a good deal or ripped off. We built a site where you can see what other companies are actually paying for SaaS and enterprise software. Buyers contribute prices via quotes, pricing proposals, and other documentation to ensure quality. We unlocked Talkdesk for Show HN users so that you can use the…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
