A surprising number of freelance translation jobs start with an agency's intake form asking which CAT tool you use — and for a large share of agencies, the acceptable answer is specifically Trados, not "a CAT tool." That single requirement shapes the real choice here more than any feature comparison: the question isn't just which tool is best, but which tool actually gets you accepted into the pipelines you want access to.
Coming from a consulting background, I default to evaluating pricing structure and long-term cost before comparing features line by line.
What actually matters for a freelance translator specifically
- Agency requirements in your specific language pairs and domains — this varies more by industry and region than general advice suggests, so check what agencies you actually want to work with are asking for before assuming Trados is required
- Subscription vs perpetual license cost over multiple years — memoQ's perpetual-license option changes the long-term math meaningfully compared to Trados, which no longer sells new perpetual licenses
- File format compatibility — .sdlxliff (Trados) and .mqxliff (memoQ) can generally be opened across tools, but confirm with a specific agency before assuming a mismatch won't cause friction
- Whether a marketplace commission model (Smartcat) fits how you find work — free access is attractive, but the commission and downward price pressure from a marketplace of translators is a real trade-off, not a free lunch
Quick comparison
| Tool | Pricing (freelance) | License type | Agency acceptance | Best for |
|---|---|---|---|---|
| Trados Studio | ~$110-420/year depending on tier and region | Subscription only (no new perpetual licenses) | Highest — required or preferred by a majority of agencies | Translators whose pipeline depends heavily on agency work |
| memoQ | ~€360/year subscription, or ~€620 perpetual license plus optional annual support | Subscription or perpetual | Strong and growing, especially in Europe | Translators who want a one-time cost and a loyal, well-regarded editor |
| Smartcat | Free for freelancers (full CAT functionality) | Free, marketplace-based | Lower — some agencies don't accept Smartcat packages | Translators just starting out, or who find work through Smartcat's own marketplace |
Trados Studio — the agency default, at a cost
By most estimates, somewhere around 60-70% of translation agencies work in Trados, which makes it less a preference than a practical requirement for a translator whose income depends on a steady stream of agency-sourced work. RWS no longer sells new perpetual licenses, meaning freelancers are locked into a subscription model going forward — annual pricing varies by region and tier, generally landing somewhere between $110 and $420 per year depending on which source and current promotion you're looking at.
Best for: translators who get most of their work through agencies that specifically require or strongly prefer Trados.
memoQ — the loyal alternative with a real perpetual option
memoQ has built a genuinely loyal following among professional translators, and its editor is often described as rewarding the time invested in learning it well. Its biggest structural advantage over Trados is the perpetual license option — roughly €620 once, plus an optional €130-144/year support and updates agreement — which breaks even against the subscription price (€360/year) in under two years for a translator planning to stick with the tool long-term. Agency acceptance is strong and growing, especially among European LSPs, though it hasn't overtaken Trados as the default requirement.
Best for: freelance translators who want to own their license outright rather than renting it indefinitely, and who work with agencies that accept memoQ files.
Smartcat — free, but the cost shows up differently
Smartcat's pitch is straightforward: full CAT tool functionality free for freelancers, with the company instead monetizing through marketplace commissions (10-15%) and charges for extras like machine translation and OCR. That makes it a genuinely low-risk way to start, particularly for translators sourcing work through Smartcat's own marketplace — but that same marketplace creates downward price pressure, since you're competing directly with translators worldwide, including from lower-cost markets. Some agencies also simply don't accept Smartcat-format packages, which narrows its usefulness for translators depending on outside agency relationships rather than the marketplace itself.
Best for: translators just starting out, working primarily through Smartcat's marketplace, or wanting a genuinely free tool to learn CAT workflows before committing to a paid license.
Bottom line
For most freelance translators with an established agency pipeline, Trados remains the pragmatic default despite the ongoing subscription cost, simply because so much agency work assumes it. memoQ is the strongest alternative — genuinely well-regarded, with a perpetual license that pays for itself within two years for anyone planning a long career in translation. Smartcat is worth starting with at zero cost, particularly if the marketplace itself is part of your income strategy, but its agency acceptance and marketplace price pressure are real trade-offs to go in aware of. Whichever CAT tool you settle on, invoicing across currencies for international agency clients is a separate problem — see our international payment platforms guide for that part of the business.

Frequently asked questions
Do I really need Trados if most of my work comes from direct clients?
Not necessarily — Trados matters most for agency work, since a large majority of translation agencies specifically require or prefer it. If your pipeline is mostly direct clients, memoQ or even Smartcat's free tier can cover the same ground for less.
Can I open a Trados (.sdlxliff) file in memoQ?
Yes, generally — memoQ can open and work with .sdlxliff files from Trados projects, and both tools support standard exchange formats like TMX for translation memory and TBX for glossaries, so databases can move between programs.
Is Smartcat actually free for freelancers?
The core CAT tool functionality is free for freelancers, but Smartcat's business model relies on marketplace commissions (typically 10-15%) if you take on work through its built-in marketplace, plus extra charges for machine translation and OCR.
Is a perpetual license better than a subscription for a freelance translator?
It depends on how long you plan to use the tool — memoQ's perpetual license (around €620 plus an optional annual support fee) breaks even against its subscription price in under two years, which matters if you expect to be translating professionally for years to come.
