From Prompt to Firmware

Generate, compile, emulate, and flash — across ARM, RISC-V, x86, and FPGA. Powered by 11 AI models.

Web IDE is free forever. Paid plans automate the full pipeline so you ship firmware, not iterate prompts.
Free — Web IDE (Manual)
You drive each step
  • 1 Write prompt, pick models & architecture
  • 2 Review generated code across models
  • 3 Manually run in sandbox (x86, ARM64, RISC-V)
  • 4 Fix errors, re-prompt, iterate
  • 5 Copy code, compile & flash locally
Paid — Agent Pipeline (Automated)
Agent does it end-to-end
  • → Describe firmware in natural language
  • → Agent generates, compiles & emulates
  • → Auto-retries on errors — no manual fixes
  • → Validates with QEMU + CMSIS checks
  • → Flashes to board via pyOCD / ST-Link / SSH

FAQ

Is the web IDE really free?
Yes. Unlimited firmware generation and sandbox execution — no daily limits, no token caps. You manually drive each step (prompt, review, run, iterate), but there's no cost. We only charge for the automated agent pipeline.
What's the difference between web and agent?
On the web, you write prompts, review code, and manually compile/run in the sandbox. With the agent, you describe what you need and it handles everything: generation, compilation, error fixing, QEMU emulation, and flashing to your board — automatically.
What architectures are supported?
ARM Cortex-M (bare-metal, CMSIS), ARM64 (Linux), x86/x64 (Linux), RISC-V, and Verilog/VHDL for FPGA. The agent supports flashing ARM boards via pyOCD, ST-Link, or SSH deployment to Linux targets.
What are credits?
Credits are consumed per firmware generation via the Agent or API. Cost depends on the model tier: Flagship (29cr), Mid (17cr), Open Source (8cr), Budget (6cr). Web IDE doesn't use credits. Free users get 500 credits to try the agent.
Do unused credits roll over?
Pro plan credits roll over to the next month. Max plan is unlimited — no credit tracking needed.
Can I use generated firmware commercially?
Yes. All generated code is yours — deploy it in any product, commercial or otherwise. No licensing restrictions.
What AI models are available?
11 models: Claude Sonnet 4.6 & Haiku, GPT-5 & GPT-4o, DeepSeek Coder & V3, Gemini 3 Pro & Flash, Llama 4, Qwen 3, and more. Use Compete mode to race models against each other and pick the best output.
How does Enterprise work?
Enterprise plans are fully custom — volume discounts, custom BSPs, dedicated support with SLA guarantees, SSO/SAML, custom model selection, and BYOK support coming soon. Contact us at support@respcode.com.
