24 alternatives to Yansu, Serious Coding

We been helping mid-market companies for the past 1.5 years and finally ready to share the internal platform publicly. Yansu (严肃) is a AI coding platform that use spec + TDD to build complex software projects. It is more like a SOP than coding agent. We focus on understanding requirements and checking outcomes against those requirements while iterating the code based on the tests. Yansu tries to learn as much tribal knowledge as possible. These are things you don’t write down in google doc or Notion. Yansu absorbs these knowledge by continuously talking to users and distilling learning from…

    Yansu▲338

    Hi HN Most teams run on a dozen SaaS tools and use maybe 20% of each. The rest is someone else's workflow that you're paying for. We built Yansu to fix that. It learns how you work — your desktop, your Slack, your Teams — and proactively builds bespoke tools tailored to you. You don’t need to prompt. It sees a pattern, builds a solution, and surfaces it for you to use or toss. Like, I do the same things before every call: look through Linkedin, see any open threads on email, read the latest blog/news of the company and any relevant slack conversations. Yansu noticed and built me an app…

    Lovable▲1,477

    Hey HN! Previous CERN physicist turned hacker here. We've developed a way to make AI coding actually work by systematically identifying and fixing places where LLMs typically fail in full-stack development. Today we're launching as Lovable (previously gptengineer.app) since it's such a big change. The problem? AI writing code typically make small mistakes and then get stuck. Those who tried know the frustration. We fixed most of this by mapping out where LLMs fail in full-stack dev and engineering around those pitfalls with prompt chains. Thanks to this, in all comparisons I found with: v0,…

    Tonkotsu▲386

    Hey HN, I’m Derek, part of a small team of ex-Facebook engineers and designer building Tonkotsu. We strongly believe that the future of software development requires every developer to become the tech lead of a team of agents. That shift requires new tools and workflows that go beyond existing IDEs or terminal agents. Tonkotsu is our take on that next-gen tool. It’s a desktop app that lets developers plan technical work, delegate many coding tasks in parallel, and then review the diffs — all in one place. Our main difference is that we tightly integrate this plan > delegate > verify loop and…

    Hey HN, Aymeric here, co-founder of Agemo and maker of CodeWords. Generating nice-looking UIs with AI has been democratized now thanks to tools like Lovable, v0 and bolt. Going from natural language to a complex back-end workflow is still an unsolved problem. We started our journey by researching neurosymbolic methods applied to software/code generation problems and it landed us a feature in the ARC-AGI report last year (https://arxiv.org/abs/2412.04604). We've now applied this research to build an AI-native workflow automation platform to enable builders of any…

    I've been exploring the (not so=) amazing potential of AI in coding and have compiled a list of tools. From AI-powered IDEs to code generators, this resource is my contribution to the community. I'm still on the fence about including txt2sql projects, as their functionality seems too basic to me. And I'm personally maintaining this, so your feedback is wellcome.

    Hi HN! We’re MutableAI (YC W22) (https://mutable.ai). Our mission is to reduce the time and cost to create high quality code using AI. We have worked at the full gamut of companies ranging from startups to big tech and have gotten the sense that many of the rote aspects of software development could be made easier, freeing up precious mental energy. Devs love Copilot, but autocomplete is just one of many ways that AI should make programming easier. We’re taking a more comprehensive approach to developer tooling that bundles Copilot-like autocomplete with documentation, custom AI…

    Hey HN, We’re two developers (co-founders) with a team of 20 who got tired of spending hours reviewing PRs, so we built Infinitcode.ai, an AI-powered code reviewer that: - *Summarizes PRs in plain English*: No more deciphering 1,000-line diff jungles - *Catches more than bugs*: Security holes, performance pitfalls, code smells, even typos (yes, we’ll flag “vurnerabilities” and vulnerabilities) - *Zero onboarding*: Works instantly—no “let me learn your codebase for weeks” nonsense. Why we’re posting: We’re in alpha and need brutal honesty. Roast our tool, mock our UI, or tell us why AI will…

    Hey HN! I’m Zach, from Coherence (https://www.withcoherence.com/). We’re building software that provides an integrated way to write, preview, and deploy code from one simple configuration.

We don’t think every team…

    Hi, we're Kevin, Chris, and Brian, the creators of JACoB (Just Another Coding Bot), an open-source AI coding agent designed to streamline the development process. As veteran developers, we know that while AI isn't perfect, it can be a valuable tool for tasks like code reviews, converting designs to React components, and writing high-quality GitHub issues. We’ve been building JACoB over the past year to assist with our real work, and today we’re open sourcing it under an Apache 2.0 license. Our goal is to create the first fully open-source tool that matches the quality and polish of many…

    Hi HN, I built my first project using an LLM in mid-2024. I've been excited ever since. But of course, at some point it all turns into a mess. You see, software is an intricate interwoven collection of tiny details. Good software gets many details right; and does not regress as it gains functionality. My bootstrapped startup, ApprovIQ (https://approviq.com) is trying to break into a mature market with multiple fully featured competitors. I need to get the details right: MVP quality won't sell. So I opted for Test-Driven Development, the classic red/green/refactor. Writing…
