[API/SDK] Show HN: Mixing Deterministic Codegen with LLM Codegen for Client SDKs Hi HN, I’m Patrick. Elias, Kevin, and I are building Sideko (<a href="https:&#x2F;&#x2F;sideko.dev" rel="nofollow">https:&#x2F;&#x2F;sideko.dev</a>), a new type of code generator for building and maintaining API client SDKs from OpenAPI specs.<p>Our approach differs significantly from traditional SDK generators in that we use structured pattern matching queries to create and update the code. Other SDK generators use templates, which overwrite custom changes and produce code that looks machine generated.<p>We’ve mixed in LLM codegen by creating this workflow: Run deterministic codegen to establish the SDK structure. Let LLMs enhance specific components where adaptability adds value and include agent rules files that enforce consistency and correctness with type checking and integration tests against mock servers. The system will retain the LLM edits, while the rest of the SDK is automatically maintained by the deterministic generator (keeping it in sync with the API). LLMs can edit most the files (see python rules and typescript rules).<p>You can try it out from your terminal: Install: npm install -g @sideko&#x2F;cli Login: sideko login Initialize: sideko sdk init Prompt: “Add a new function that…”<p>Check out the repo for more details: <a href="https:&#x2F;&#x2F;github.com&#x2F;Sideko-Inc&#x2F;sideko" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Sideko-Inc&#x2F;sideko</a> We’d love to hear your thoughts!

[Other] Show HN: Stagewise – frontend coding agent for real codebases Hey HN, we&#x27;re Glenn and Julian, and we&#x27;re building stagewise (<a href="https:&#x2F;&#x2F;stagewise.io">https:&#x2F;&#x2F;stagewise.io</a>), a frontend coding agent that inside your app’s dev mode and that makes changes in your local codebase.<p>We’re compatible with any framework and any component library. Think of it like a v0 of Lovable that works locally and with any existing codebase.<p>You can spawn the agent into locally running web apps in dev mode with `npx stagewise` from the project root. The agent lets you then click on HTML Elements in your app, enter prompts like &#x27;increase the height here&#x27; and will implement the changes in your source code.<p>Before stagewise, we were building a vertical SaaS for logistics from scratch and loved using prototyping tools like v0 or lovable to get to the first version. But when switching from v0&#x2F; lovable to Cursor for local development, we felt like the frontend magic was gone. So, we decided to build stagewise to bring that same magic to local development.<p>The first version of stagewise just forwarded a prompt with browser context to existing IDEs and agents (Cursor, Cline, ..) and went viral on X after we open sourced it. However, the APIs of existing coding agents were very limiting, so we figured that building our own agent would unlock the full potential of stagewise.<p>Since our last Show HN (<a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44798553">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44798553</a>), we launched a few very important features and changes: You now have a proprietary chat history with the agent, an undo button to revert changes, and we increased the amount of free credits AND reduced the pricing by 50%. We made a video about all these changes, showing you how stagewise works: <a href="https:&#x2F;&#x2F;x.com&#x2F;goetzejulian&#x2F;status&#x2F;1959835222712955140&#x2F;video&#x2F;1" rel="nofollow">https:&#x2F;&#x2F;x.com&#x2F;goetzejulian&#x2F;status&#x2F;1959835222712955140&#x2F;video&#x2F;...</a>.<p>So far, we&#x27;ve seen great adoption from non-technical users who wanted to continue building their lovable prototype locally. We personally use the agent almost daily to make changes to our landing page and to build the UI of new features on our console (<a href="https:&#x2F;&#x2F;console.stagewise.io">https:&#x2F;&#x2F;console.stagewise.io</a>).<p>If you have an app running in dev mode, simply `cd` into the app directory and run `npx stagewise` - the agent should appear, ready to play with.<p>We&#x27;re very excited to hear your feedback!

[Other] Show HN: SecretMemoryLocker – File Encryption Without Static Passwords I built SecretMemoryLocker (<a href="https:&#x2F;&#x2F;secretmemorylocker.com" rel="nofollow">https:&#x2F;&#x2F;secretmemorylocker.com</a>), a file encryption tool that generates keys dynamically from your answers to personal questions instead of using a static master password. This makes offline brute-force attacks much more difficult. Think of it as a password manager that meets mnemonic seed recovery, but without storing any sensitive keys on disk.<p>Why? I kept losing master passwords and wanted a solution that wasn&#x27;t tied to a single point of failure. I also wanted to create a &quot;digital legacy&quot; that my family could access only under specific conditions. The core principle is knowledge-based encryption: the key only exists in memory when you provide the correct answers.<p>Status: * MVP is ready for Windows (.exe). * Linux and macOS support is planned. * UI is available in English, Spanish, and Ukrainian.<p>Key Features:<p>* No Static Secrets: No master password or seed phrase is ever stored. The key is reconstructed on the fly.<p>* Knowledge-Based Key Generation: The final encryption key is derived from a combination of your personal answers and file metadata.<p>* Offline Brute-Force Resistance: Uses MirageLoop, a decoy system that activates when incorrect answers are entered. Instead of decrypting real data, it generates an endless sequence of AI-created questions from a secure local database, creating an illusion of progress while keeping your real data untouched.<p>* Offline AI Generation Mode: Optional offline Q&amp;A generator (prototype).<p>How It Works (Simplified):<p>1) Files are packed into an AES-256 encrypted ZIP archive.<p>2) A JSON key file stores the questions in an encrypted chain. Each subsequent question is encrypted with a key derived from the previous correct answer and the file&#x27;s hash. This forces you to answer them sequentially.<p>3) The final encryption key for the ZIP file is derived by combining the hashes of all your correct answers. The key derivation formula looks like this:<p><pre><code> K_final = SHA256(H(answer1+file_hash) + H(answer2+file_hash) + ...) </code></pre> (Note: We are aware that a fast hash like SHA256 is not ideal for a KDF. We plan to migrate to Argon2 in a future release to further strengthen resistance against brute-force attacks.)<p>To encrypt, you provide a file. This creates two outputs: your_file.txt → your_file_SMLkey.json + your_file_SecretML.zip<p>To decrypt, you need both files and the correct answers.<p>Install &amp; Quick Start: Download the EXE from GitHub Releases (no dependencies needed):<p><a href="https:&#x2F;&#x2F;github.com&#x2F;SecretML&#x2F;SecretMemoryLocker&#x2F;releases" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;SecretML&#x2F;SecretMemoryLocker&#x2F;releases</a><p>Encrypt:<p><pre><code> SecretMemoryLocker.exe --encrypt &quot;C:\docs\important.pdf&quot; </code></pre> Decrypt:<p><pre><code> SecretMemoryLocker.exe --decrypt &quot;C:\docs\important_SMLkey.json&quot; </code></pre> I would love to get your feedback on the concept, the user experience, and any security assumptions I&#x27;ve made. Thanks!

[Database] Show HN: Base, an SQLite database editor for macOS I recently released v3 of Base, my SQLite editor for macOS.<p>The goal of this app is to provide a comfortable native GUI for SQLite, without it turning into a massive IDE-style app.<p>The coolest features are<p>- That it can handle full altering of tables, which is quite finicky to do manually with SQLite.<p>- It has a more detailed display of column constraints than most editors. Each constraint is shown as an icon if active, with full details available on clicking the icon.<p>This update also adds support for attaching databases, which is a bit fiddly with macOS sandboxing.<p>I&#x27;d love to hear any feedback or answer any questions.
