Fictiv, Fractory, Geomiq, Protolabs, RapidDirect and Xometry are six online routes to investigate when buying custom CNC parts in 2026. This is an editorial comparison of quoting and fulfillment models—not a market-share, revenue, capacity or quality ranking. We did not find a like-for-like public dataset that makes all six directly comparable by size. The order below is alphabetical, and “top six” means six relevant options selected by the stated criteria, not the six largest firms.
Research cutoff: 26 September 2026. Inclusion required a current official English-language page describing both custom CNC machining and a digital CAD-upload or online quote path. The comparison relies on the companies' own descriptions; it does not independently audit a factory, supplier network, certification, lead time or delivery performance. For general sourcing-path decisions, read where to source custom CNC parts. Our earlier six-supplier shortlist covers a different question and includes direct-service suppliers that are not necessarily online-platform comparators.
What “platform” and “larger” mean here
An online CNC platform accepts a part file and order configuration through a digital workflow, then quotes or routes manufacturing. It may operate its own equipment, use a managed partner network, or combine both. A website contact form alone does not meet this article's definition.
“Larger” is not used as a numeric rank. Public companies disclose consolidated revenue under accounting rules; private companies may report users, partner counts or machines using different definitions and dates. Those figures cannot be combined into a fair CNC-platform size league table. We therefore do not score the six by revenue, network size, annual throughput or “best” quality. This shortlist is limited to accessible English buying routes and is not exhaustive by geography.
Compare the quote workflow before the platform name
| Platform (alphabetical) | Officially described digital route | Buyer question to verify |
|---|---|---|
| Fictiv | Online CNC quote; simple parts may be instant, complex drawing-led parts reviewed | When does a human resolve drawing conflicts and release the final quote? |
| Fractory | CAD-upload CNC quote with configurable material and other options | Does this workflow serve the delivery country, quantity and drawing complexity? |
| Geomiq | CAD upload and instant or 24-hour CNC quote; partner-network manufacturing | Which source, inspection record and repeat-order controls apply? |
| Protolabs | CAD-upload ProDesk quote and distinct factory/network paths | Which fulfillment path is in this quote? |
| RapidDirect | Online CNC quote and project/order-management functions | Which operations are performed at owned sites versus network partners? |
| Xometry | Online CNC quote through a managed supplier network | What location, source-change and documentation controls apply? |
The table reports available workflow descriptions—not a live test of quote speed, pricing, capacity or suitability for a specific drawing.
Fictiv: check the handoff from instant estimate to reviewed quote
Fictiv's CNC page describes an online CNC quote and a digital supply-chain platform. Its help center distinguishes a simple part that may receive an instant quote from a more complex part or supplemental drawing that receives human review. That distinction matters more than a headline “instant” claim: confirm when material, tolerance, finishing and inspection notes become binding.
Ask who owns the drawing reconciliation, process change approval and delivered inspection evidence. Do not transfer Fictiv's published example tolerances or timing to your part without a reviewed quote.
Fractory: verify service geography and quote limits
Fractory's CNC service page describes a file-upload platform, configurable materials and partner-network production. Its online-quote text is qualified for particular order types and geography; it references UK delivery and a lower-value prototyping/low-volume flow. An international buyer should confirm whether the digital path, currency, import handling and support apply to the actual destination before comparing a displayed price.
If the drawing requires special inspection or finishing, ask whether those requirements remain in the online configuration or move to an engineer-reviewed quote.
Geomiq: distinguish a quote from a manufacturing commitment
Geomiq's CNC page describes CAD upload, an instant or 24-hour quote path and selection of a manufacturing partner. It also describes quality-control and delivery stages. Those are provider statements, not independent proof of performance. Ask where the selected shop is located, what evidence accompanies release and how the source is controlled on a repeat order.
For a multi-face part, attach the controlled drawing and ask how the critical datum and feature relationships will be measured. Do not assume an automated model analysis has interpreted every note.
Protolabs: identify factory versus network fulfillment
Protolabs' CNC page expressly separates factory and network capabilities. Its ProDesk help page describes CAD upload, configuration and analysis. A buyer can use the digital route for a quick comparison, but should confirm which of the two fulfillment models applies to the quoted feature set and finishing requirements. Hubs/Protolabs Network is not counted as a separate seventh company.
Ask whether the selected factory or network route changes available materials, process, dimensional acceptance or documentation. A quote option for one route is not automatically an option for the other.
RapidDirect: clarify owned-factory and network responsibilities
RapidDirect's CNC page describes online quoting and production through owned facilities and a manufacturing network. Its online-platform page discusses DFM feedback, communication and order management. These make it relevant to buyers who want an online China-based sourcing path, but the site-wide machine counts and lead-time claims are not a verified capability for an arbitrary part.
Ask which facility and sub-processes are assigned to the actual order, who approves a finishing deviation, and whether the final inspection evidence covers the drawing's critical characteristics.
Xometry: define network-source controls
Xometry's CNC service page describes online quotes and a managed supplier network. For a prototype this can simplify finding capacity. For repeat production or restricted designs, the important question is not the headline network count but the controls on manufacturing location, source changes, material records and quality release for the specific purchase order.
Ask what is included in the base quote versus an inspection or traceability option. A platform-level certification statement should not be assumed to mean every network shop holds the same certificate or that its scope covers your part.
Run a controlled comparison on one representative part
Use the same STEP file, PDF drawing revision, material/temper, finish, quantity, delivery address and inspection requirement across all candidates. Keep the quantity and date realistic; changing either can alter the quoted route. A drawing-controlled bore, thread or datum relationship is a better test than a generic block. If the platform cannot interpret a requirement through the form, ask for a manual engineering review.
Compare six outputs: (1) quote scope and exclusions, (2) identified production route, (3) DFM questions and assumptions, (4) finishing and post-finish acceptance, (5) inspection deliverables, and (6) delivered cost and schedule. A price generated before the drawing is reviewed is a screening signal, not an award decision. See how to compare machining quotes for a more detailed RFQ method.
Do not upload confidential customer drawings simply to test six tools. Follow your organization's NDA and data-sharing approval process first; use a non-sensitive test geometry when evaluating interfaces. For live procurement, request the actual contractual terms on data retention, subcontracting, ownership of changes and acceptance.
When a platform is not the best first route
If one hard-to-machine feature controls the part, a named process specialist may resolve feasibility before a broad online RFQ. If a program needs controlled repeat sourcing, ask whether the platform will lock the manufacturing source and how it will handle revisions. If the part needs extensive engineering collaboration, a direct factory can sometimes simplify communication—but only after it demonstrates the necessary process and inspection route. Conversely, a well-managed platform may be suitable for complex work when it provides explicit engineering review and traceable responsibilities. Do not infer outcome from business model alone.
The six names above are research starting points, not endorsements or claims of a commercial relationship with JIZAO. If you would like a separate drawing-led response from JIZAO, submit the model and controlled RFQ package; no capability, price or lead time is promised until review.
Method and update note: official service/help pages linked inline were checked on 26 September 2026. Company descriptions may change. No supplier site visit, independent process audit, paid placement, fabricated market-size comparison or numerical ranking was used.
