Onform is an MCP-native form builder — the first form tool designed around MCP as its primary interface rather than a visual drag-and-drop UI. You describe the form you want to Claude or Cursor, and Onform's MCP server creates it, adds fields, sets validation rules, configures submissions, and returns a live URL. No dashboard, no templates, no GUI required. The platform handles all the backend infrastructure: submission storage, email notifications, spam filtering, and export to CSV or webhook. Each form has a public URL and an admin API. Updating a form is as simple as telling your agent what to change. Onform is built for developers who create forms as part of larger agent workflows — onboarding flows, data collection pipelines, feedback loops — where manually clicking through a SaaS dashboard breaks the automation chain. It supports multi-step forms, conditional logic, file uploads, and custom branding via MCP tool parameters.

Vera is a programming language built from the ground up for LLMs to write — not humans. Named after the Latin word for truth, it compiles to WebAssembly and runs in both the CLI and browser. Its most radical design choice: it eliminates variable names entirely, replacing them with typed De Bruijn structural references (like `@Int.0` for the most recent integer binding). Research suggests naming confusion is one of the biggest failure modes in AI-generated code — Vera removes the problem at the language level. Every function in Vera must declare `requires()` preconditions, `ensures()` postconditions, and `effects()` side-effect declarations. The compiler uses Z3 formal verification to check contracts at every call site, meaning the AI can't ship code that violates its own preconditions. Error messages are structured JSON with stable codes — written as instructions for AI systems to parse and fix, not human developers to read. Benchmark results are striking: on VeraBench, Kimi K2.5 achieves 100% correctness writing Vera code, outperforming both Python (86%) and TypeScript (91%) implementations. At v0.0.127 with 810+ commits, 127 releases, 3,638 tests, and a 13-chapter spec, this is a serious project — not a weekend experiment. If AI is going to write most of our code, perhaps the code should be designed for AI to write.
Reviewer scorecard
“MCP-first is the right design philosophy for developer tools in 2026. Being able to spin up a form with submission handling and webhook delivery through a Claude conversation — without touching a UI — removes a surprisingly annoying friction point in agent-built workflows.”
“The contracts-first approach is genuinely compelling — I've spent too many hours debugging AI-generated code that violated implicit invariants. Having the compiler enforce preconditions at every call site is the kind of guardrail I'd actually trust. The WASM compilation target means you can run this anywhere, and 3,638 tests suggests this isn't vaporware.”
“Typeform, Tally, and even Google Forms are hard to beat on price and ecosystem. The MCP angle is clever but the addressable market is narrow — most teams who need forms don't have an agent workflow they need to fit it into. The moat depends entirely on MCP adoption velocity.”
“A language with no variable names sounds like an academic exercise, not something that'll ship real software. Even if LLMs do great on VeraBench, the ecosystem is zero — no libraries, no community, no integrations. You'd be asking your team to maintain code written in a language nobody else on Earth can read. That's a hard sell even if the AI loves it.”
“Every data collection touchpoint that can be managed by an agent will be. Onform is a small example of how MCP will quietly restructure the SaaS tool category — tools that can't be controlled programmatically via agents will lose to tools that can.”
“Vera represents a fundamental rethink: what if programming languages were designed for their actual authors in 2026 — which are predominantly AI systems? The formal verification backbone means AI-generated code carries a proof of correctness, not just a vibe. This is early, but the trajectory points to a world where AI writes formally verified software by default.”
“For most creative use cases — reader surveys, client intake, waitlist signups — the visual feedback of building a form matters. Describing a form in text and trusting the agent to get the layout right sounds good but loses something in translation for design-sensitive contexts.”
“I love the philosophical angle — a language where the 'author' is the machine. But until there's a visual toolchain, a debugger humans can read, and something I can demo to a client, this lives in research territory. The JSON error messages designed for AI systems are clever but leave human reviewers completely out of the loop.”
