monogate forge
Explore EML. Compile with Forge.
Monogate Forge is the EML→multi-target compiler: one EML math source emits software, GPU shaders, hardware (FPGA), LLVM IR, and formal proofs.
Every target is free — no Pro tier. pip install monogate-forge, or try it in your browser at efrog.dev.

public status
Forge is free — every compile target, no Pro tier.
The compiler
pip install monogate-forge gives the full compiler: one EML source emits any target, with no license token. Or compile in the browser at efrog.dev.
The research package
pip install monogate ships the EML math library on its own: the core operator, elementary functions, BEST routing, optimizer utilities, symbolic search, and PyTorch activation experiments.
Source-available
The full compiler source ships in the pip install wheel. Hardware targets (Verilog, VHDL, Chisel), GPU shaders, LLVM IR, and Lean 4 proof artifacts all emit from the same EML source.
how it works
From one EML source to every compile target.
01Install the Forge compilerpip install monogate-forge — the full EML→multi-target compiler, every target free.
02Write EMLCore EML arithmetic, elementary functions, BEST routing, and optimizer passes.
03Compile to any targetSoftware, GPU shaders, hardware (Verilog / VHDL / Chisel), LLVM IR, and formal proofs — one source.
04Check the outputLean 4 proof obligations emit alongside the code; Lean's #print axioms says which of them are proved.
05Ship itSame EML, every target, no license. Or compile in the browser at efrog.dev.
One source.
Every target — software, GPU, hardware, IR, proofs. Free.
how it works
Measure, verify, compile — all from one EML source.
Measure
EML expressions can be measured and optimized as symbolic math objects.
BEST routing can choose cheaper operator families than an all-EML baseline.
Verify
Lean 4 proof obligations for the contracts you declare emit alongside the compiled code.
Whether each one is proved is a separate step, answered by Lean's #print axioms.
Compile
pip install monogate-forge emits any target — software, GPU shaders, hardware (FPGA), and LLVM IR.
Each target computes in its own arithmetic: the FPGA targets are fixed point, so their output does not match IEEE-754 software bit for bit.
examples
One EML source, compiled to many targets.
These cards illustrate the EML→target flow. To compile in your browser with no install, use efrog.dev, or run it locally with pip install monogate-forge.
industry coverage
22 verticals in the private roadmap inventory.
These cards are not public compiler availability claims. The four example-pending cards are being rebuilt as reproducible public monogate snippets; the rest remain private evidence until their artifacts are published.

Forge @verify obligations auto-close in Lean (measured 2026-09-05)
Installable today: pip install monogate-forge for the full compiler — C, Rust, Verilog, VHDL, HLSL, LLVM, Lean, MATLAB, and more, every target free. Or pip install monogate for the EML math, routing, optimization, search, and ML package.
About that 79.9%: 573 of 717 Lean 4 proof obligations in the Forge @verify(lean) corpus close automatically against MachLib, with no hand-written proof; the other 144 do not. MachLib measured this on 2026-09-05 under Lean v4.32.2 with foundations/scripts/closerate.sh, which you can re-run, and records it as a measurement rather than a gate, so it is not re-measured on every change. This site checks the figure against MachLib's README before each deploy.
