Dirac is an open-source AI coding agent built by Dirac Delta Labs that shot to the top of TerminalBench-2 with a 65.2% score using Gemini Flash — while costing 64.8% less than competing agents. Forked from Cline and rebuilt with a performance-first architecture, it handles file modifications, multi-file refactoring, terminal commands, and browser automation through an approval-based workflow. What sets Dirac apart is its technical substrate: hash-anchored edits replace fragile line-number targeting with stable content hashes, AST-native processing understands language structure for TypeScript, Python, and C++, and multi-file batching reduces LLM roundtrips by processing several files per call. The result is a leaner context that preserves model reasoning quality without burning through tokens. Available as both a VS Code extension and an npm CLI, Dirac supports Anthropic, OpenAI, Google, Groq, and Mistral as backends. Its Apache 2.0 license and strong TerminalBench showing on the affordable Gemini Flash model make it a compelling pick for developers who want production-grade coding assistance without the per-token bill shock.

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.
Reviewer scorecard
“Topping TerminalBench-2 while being 64.8% cheaper is the kind of benchmark that actually matters to developers. The hash-anchored editing and AST-native approach fix the two most annoying failure modes of existing coding agents — wrong line edits and syntax-blind refactors.”
“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.”
“It's a Cline fork with smart optimizations — not a ground-up rethink. TerminalBench-2 scores are reproducible only if you're running similar tasks; complex real-world codebases may tell a different story. Also, requiring your own API key still means real money.”
“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.”
“The race to build the cheapest, most accurate coding agent is the real infrastructure play of 2026. Dirac's multi-provider support and lean context model are exactly the primitives that make agentic coding deployable at scale — not just on powerful machines.”
“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.”
“The VS Code extension makes it approachable for designers who code. Approval-based workflows mean it won't silently rewrite your carefully named CSS classes. Worth trying if you've been burned by agents that act first and apologize later.”
“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.”
