# MakeIRL vs Sierra Circuits Better DFM: source gate or gerber checker?

Choose Better DFM when you want a free gerber/ODB++ manufacturability check with a real netlist comparison — it cross-references your files against an IPC-356 netlist to flag opens and shorts, and emails you the report. Choose MakeIRL when you want a paid, fab-neutral gate on the KiCad project itself: ERC on the schematic, DRC, schematic-to-PCB parity, and BOM lines checked against live distributor stock.

Better DFM's netlist comparison catches opens/shorts in exported manufacturing files; MakeIRL's parity check catches schematic-vs-layout drift in the KiCad source before export — related problems, caught at different stages.

## Side by side

|  | MakeIRL | Better DFM |
| --- | --- | --- |
| Maker | MakeIRL | Sierra Circuits |
| Price | $79 one-time per board release, no subscription (as of July 2026) | Free online tool (as of July 2026) |
| Runs as | Online release gate; also runs from Claude Code / Cursor via MCP | Online file checker |
| Input files | Native KiCad source: .kicad_sch + .kicad_pcb | Gerber RS-274X or ODB++, submitted as .zip or .tgz; optional IPC-356 netlist for comparison |
| What it checks | ERC on the schematic, DRC on the layout, schematic ↔ PCB parity, BOM line completeness with MPN / package sanity and availability against live distributor stock, gerber / drill / placement export integrity, named heuristic checks (power, reset, programming, connector patterns) | A 40-point checklist across signal layers (conductor width, spacing, annular ring), plane layers, solder mask, silkscreen, and drill, plus netlist comparison against IPC-356 to flag opens and shorts |
| How results arrive | Plain-English report with a BLOCKED / REVIEW / READY verdict; every report states explicitly that function is not proven | Email report with the DFM analysis, netlist comparison results, and Gerber layers as PDF; offers optional automated solder mask / silkscreen optimization and instant quotes for standard boards |
| Fab tie-in | Fab-neutral — the preflight is not tied to any one factory's ordering pipeline | Built by Sierra Circuits; integrates instant quoting for their fabrication |

## When each is the better pick

### When Better DFM is the better pick

You have an IPC-356 netlist and want a free gerber-vs-netlist comparison that flags opens and shorts, with a US fab behind it.

It is free online tool (as of July 2026), so if a gerber-level check is all you need, there is no cost to trying it.

### When MakeIRL is the better pick

You want one gate over the whole KiCad project before gerbers exist: ERC on the schematic, DRC on the layout, schematic ↔ PCB parity, and BOM lines checked against live distributor stock. It costs $79 one-time per board release (as of July 2026) and is fab-neutral.

Honest limits: KiCad projects only, it costs money while fab-side checkers are free, and it does not replace the manufacturer's own DFM review before production. When every check passes, the report reads “READY FOR MANUFACTURING — function not proven” — no automated check can prove a circuit does what you meant.

## Frequently asked questions

**Q: Is Better DFM free?**
Yes, Sierra Circuits offers Better DFM as a free online tool (as of July 2026). MakeIRL's automated preflight is $79 one-time per board release.

**Q: What file formats does Better DFM accept?**
Gerber RS-274X or ODB++ submitted as .zip or .tgz, with an optional IPC-356 netlist for the opens/shorts comparison. MakeIRL takes native KiCad source files (.kicad_sch and .kicad_pcb) instead.

**Q: Do I still need my fab's DFM review if I use MakeIRL?**
Yes. MakeIRL is a pre-order release gate on your design source; your chosen manufacturer will still run its own process-specific DFM review, and tools like Better DFM are one way fabs surface that early.
