# MakeIRL vs JLC DFM: KiCad source gate or free gerber DFM check?

Choose JLC DFM when you are ordering from JLCPCB and want a free gerber-level DFM/DFA analysis matched to their process. Choose MakeIRL when you want a fab-neutral, paid preflight of the KiCad source itself — schematic ERC, layout DRC, schematic-to-PCB parity, and BOM lines checked against live distributor stock — before you even export gerbers.

They check different layers of the stack: JLC DFM analyzes exported gerbers against JLCPCB's manufacturing process, while MakeIRL gates the KiCad project (schematic + layout + BOM) before export. Many teams can sensibly use both.

## Side by side

|  | MakeIRL | JLC DFM |
| --- | --- | --- |
| Maker | MakeIRL | JLCPCB |
| Price | $79 one-time per board release, no subscription (as of July 2026) | Free (as of July 2026) |
| Runs as | Online release gate; also runs from Claude Code / Cursor via MCP | Online web tool, nothing to download |
| Input files | Native KiCad source: .kicad_sch + .kicad_pcb | Gerber files uploaded as zip/rar, up to 50 MB |
| 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) | DFM and DFA analysis across five modules — traces, solder mask, drilling, silkscreen, and component assembly — using a 30+ point checklist, plus BOM matching against JLCPCB's component library |
| How results arrive | Plain-English report with a BLOCKED / REVIEW / READY verdict; every report states explicitly that function is not proven | 2D/3D visualization in the browser and a downloadable PDF report |
| Fab tie-in | Fab-neutral — the preflight is not tied to any one factory's ordering pipeline | Built by JLCPCB and integrated with JLCPCB fabrication and assembly |

## When each is the better pick

### When JLC DFM is the better pick

You are ordering from JLCPCB and want a free pre-check aligned to their process, including BOM matching against their parts library.

It is free (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 JLC DFM free?**
Yes. JLCPCB describes it as a free online DFM tool (as of July 2026). MakeIRL's automated preflight is $79 one-time per board release.

**Q: Does JLC DFM check my schematic?**
JLC DFM analyzes uploaded gerber files (zip/rar, up to 50 MB) plus BOM matching against JLCPCB's library. It does not take KiCad schematic source. MakeIRL runs ERC on the .kicad_sch and checks schematic-to-PCB parity, which requires the KiCad project files.

**Q: Does either tool prove my circuit works?**
No. Neither a gerber DFM check nor MakeIRL's preflight can prove functional correctness. MakeIRL's passing verdict reads “READY FOR MANUFACTURING — function not proven”, and that limitation applies to every automated checker in this comparison.
