ConveyThis vs Proxylang: A Detailed Comparison for 2026

ConveyThis translates websites through a JavaScript snippet or a CMS plugin, offers 210 languages, and runs one of the longest pricing ladders in the category: twelve paid steps from $12 to $960 a month. Proxylang supports 68 languages and takes a different approach to delivery, built around server-side indexing for search engines while visitors still get a fast page.

Neither one asks you to rebuild your site or keep a second copy of every page. What separates them is how the translation reaches the page, what you get at each price, and a short list of features only one of them has.

Where they actually differ

First, something people get wrong about both tools: they meter usage the same way.

Each gives you a pool of translatable words that is counted once per language and does not reset monthly. ConveyThis calls these “free machine words,” Proxylang calls them included words. Translate one page into five languages on either tool and you spend five languages’ worth of words from the pool.

Each also caps monthly page loads. ConveyThis calls these “translation requests,” Proxylang calls them page views. Neither tool is “unlimited traffic” until you reach the very top of the ladder.

So the honest comparison is not one usage model against another. It is three things: how the translation is delivered, what each price band buys, and the features that only exist on one side.

1. Architecture and install

ConveyThis installs as a plugin (WordPress, Shopify, Webflow, Squarespace, Wix, Joomla, BigCommerce, and 50+ other CMS platforms) or as a JavaScript snippet for custom sites. It serves each language on a subdirectory, subdomain, ?lang parameter, or a second-level domain such as example.es. The custom-domain option is a paid feature.

Proxylang offers three install methods:

Script tag — one line of code, no DNS change, live in about 60 seconds. Available on every plan, including free. Works with Squarespace, Wix, Shopify, Cafe24, and anything else that lets you paste a script.
Hybrid mode — one line of code plus a DNS change, available on the Start plan ($39/mo) and above. Your visitors get instant translation in the browser, while Google and other search engines are served fully translated HTML from the server. This is the server-side indexing that gets your translated pages ranked.
Full server-side mode — no code on your site at all, just a DNS change, available on the Pro plan ($99/mo) and above. Everything is translated on the server before it reaches anyone, visitors and search engines alike. That’s a mid-tier plan, not an enterprise contract.

ConveyThis translates server-side, so search engines read the translation straight from the page source. That’s solid for indexing, and it’s on every paid plan. It also means every human visitor takes the same server-side path and waits for it.

Proxylang’s hybrid mode splits the two audiences instead. Visitors get the fast in-browser translation, search engines get pre-built translated HTML, from one setup. ConveyThis doesn’t document an equivalent split, and it doesn’t document a DNS-level install either. Its integrations run through a plugin or the JavaScript snippet.

2. What each price band buys

ConveyThis runs twelve paid steps from $12 to $960. Proxylang runs six, from $15 to $699. Lined up by price:

Price band	Proxylang	ConveyThis
Free	$0 — 2K words, 1 language, 1.5K views/mo	$0 — 5K words, 1 language, 2.5K requests/mo
Entry	Lite $15/mo — 50K words, 5 languages, 15K views	Starter $12/mo — 30K words, 1 language, 15K requests
Lower-mid	Start $39/mo — 200K words, all 68 languages (3 indexed), 50K views	Business $24/mo — 100K words, 3 languages, 50K requests
Mid	Pro $99/mo — 1M words, all 68 languages (10 indexed), 150K views	Pro+ $110/mo — 700K words, 9 languages, 350K requests
Upper	Business $399/mo — 5M words, all 68 languages (25 indexed), 750K views	Corporate+ $320/mo — 2M words, 30 languages, 1M requests
Top	Global $699/mo — 20M words, all 68 languages (50 indexed), unlimited views	Advanced+ $640/mo — 6M words, 80 languages, 3M requests

Both bill yearly at ten months, so a year costs two months less than twelve monthly payments. Enterprise on both is quote-based. “Indexed” is how many languages Proxylang serves to search engines as separate URLs; visitors can pick any of the 68 on Start and up.

Read the word column and Proxylang lists more per dollar at every paid tier. Global gives you 20M words at $699 where ConveyThis’s $640 tier gives 6M, and Global drops the page-view cap that every ConveyThis plan keeps.

That column isn’t the whole plan, though. Proxylang includes things ConveyThis sells separately or doesn’t sell at all.

Live Chat is the big one. Every Proxylang plan from Start upward includes multilingual Live Chat. A visitor writes in their language, your team answers in yours, and Proxylang translates both directions in the thread.

The allowance scales with the plan. Start includes 2,000 translated messages a month, Pro includes 10,000, Business and Global include 50,000. Sold on their own those three tiers are $7, $19, and $39 a month.

ConveyThis has no chat product. If you want translated live chat next to a ConveyThis plan, you’re picking a second vendor, paying a second bill, and wiring the widget in yourself.

Start unlocks the SEO features. $39 buys hybrid mode, the per-language SEO dashboard, indexable /lang/ URLs, and daily sitemap monitoring. ConveyThis’s $24 Business plan matches the raw quota and includes none of that.

Three more things a quota table doesn’t show:

Search engine traffic doesn’t touch your Proxylang page views, and words translated for search engines bill at a quarter of the normal rate. If Google visits your site often, your real view allowance sits well above the number printed on the plan.
ConveyThis caps a single page at 30,000 source words. Long legal pages, big catalogues rendered as one document, and large documentation pages can exceed it.
Proxylang stops counting your sites; ConveyThis never does. ConveyThis allows one site on its four cheapest plans and climbs slowly from there, and even the $960 top tier stops at 50. Proxylang goes unlimited from Business ($399) upward, and gives you more sites than ConveyThis at the same money below that: two on Start where their $24 plan gives one, five on Pro. Extra sites also draw on the same word balance rather than costing a separate subscription, so a second site costs you only the words it uses.

3. Features one tool has and the other doesn’t

Proxylang-only: hybrid mode, where visitors and search engines each get the version that suits them; multilingual Live Chat; reverse search translation; automatic image translation; and a visual editor on the free plan.

ConveyThis-only: 210 languages against Proxylang’s 68, a human-translation marketplace in the dashboard, and 50+ CMS plugins.

One footnote on that language count. ConveyThis’s catalogue is 210 languages, but no plan gives you all of them. Each plan caps how many you can switch on: 1 on Starter, 3 on Business, 5 on Pro, 14 on Optimum, and 100 at the $960 top tier. The 210 figure is the menu, not the plan.

Multilingual SEO

Both get the fundamentals right: a separate address for each language, translated page titles and descriptions, and hreflang tags, which are the signals that tell Google your Spanish page and your English page are the same page in two languages rather than duplicate content.

ConveyThis adds hreflang tags automatically, creates a unique indexable URL per language on a subdirectory or subdomain, translates meta title and description along with JSON-LD structured data, and renders the translation into the HTML server-side so search engines never have to run JavaScript. These sit on the paid plans. Its free tier is one language and 5,000 words, so SEO barely applies there anyway.

Proxylang adds automatic hreflang on every plan. Localized URLs, the per-language SEO dashboard, and sitemap monitoring unlock with hybrid mode on the Start plan ($39/mo) and above. On Free and Lite, translation happens in the visitor’s browser, so search engines see only your original language. In hybrid and full server-side modes Proxylang serves search engines real translated HTML rather than JavaScript they have to run first.

Sitemap monitoring frequency scales with the plan: daily on Start, every four hours on Pro, hourly on Business, real-time on Global.

Proxylang also pings Naver, Yandex, Seznam, and Yep with your updated sitemap alongside Bing, and submits to Google Search Console. That matters if a chunk of your traffic comes from South Korea or Russia, where Google isn’t the default.

Translation quality and editing

ConveyThis combines machine translation with brand rules and translation memory, layers AI on top, and lets you order professional human translation from inside the dashboard through a partnered US agency. It includes a visual editor for clicking any element and rewriting the translation, available on paid plans.

Proxylang runs the same AI engine on every plan, free one included. No credit meter, no cheaper engine on the lower tiers, no add-on to unlock the good version.

The difference shows up in how it reads your page. Most tools translate one sentence at a time and never see what surrounds it, which is why they render a “Book” button as a noun and turn “Free” into “at no cost” on a page about availability. Proxylang reads the whole page before it translates a word of it. What comes back reads like a person wrote it in that language, rather than like your English was converted into it.

That gap gets much wider once you leave Europe. English into Spanish or German mostly means swapping words and keeping the order. Asian languages don’t work that way. Korean and Japanese are the sharpest example: the sentence has to be rebuilt from the ground up, and the small grammar pieces holding it together change depending on the word sitting in front of them. Tools that don’t account for this produce something a customer can follow but would never write, and in these markets that reads as cheap.

One case almost every tool gets wrong: a sentence interrupted by a link or a bit of bold text. On your page, “Read our shipping guide before you order” is three separate pieces of content. Other tools translate each piece alone and glue the results together, which a native speaker spots immediately. Proxylang puts the sentence back together, translates it as one thought, then restores your formatting around the result.

Glossary and do-not-translate rules come with every plan, so your brand and product names survive intact in all 68 languages. The visual editor is on every plan too, including free, so you can rewrite any line on the live page and watch it change.

Image translation exists on both. ConveyThis detects and translates text inside images, buttons, and forms. Proxylang translates image text automatically as well: you tag an image and the AI generates a version per language with fonts, colors, and layout kept. On Proxylang it’s a separate credit pack rather than something metered against your word quota, starting at $5 for 10 images and dropping to $0.35 each at the 100-image pack. Packs are available on any paid plan and last 12 months.

Reverse search translation is Proxylang-only. A visitor searches your site in their language, Proxylang translates the query, runs it against your original-language content, and returns the results translated. It’s also a credit pack: $9.99 for 10,000 searches, down to about $0.0007 per search on the 200,000 pack. ConveyThis documents nothing equivalent.

Platform support

Both work with WordPress, Shopify, Wix, Squarespace, Webflow, and WooCommerce. ConveyThis has the wider plugin catalogue at 50+ integrations, including Joomla, Drupal, Bubble, BigCommerce, Weebly, and Jimdo.

Proxylang covers modern JavaScript frameworks: React, Vue, Next.js, Nuxt, Svelte, SvelteKit, Angular, Astro, Hugo, Gatsby, Framer, IMWEB, and Cafe24. Hybrid mode was built for apps that draw their own pages in the browser, so content that appears after load gets translated too, without the app breaking underneath it.

Proxylang also ships a free WordPress plugin on wordpress.org.

Who should choose which

ConveyThis makes sense if:

You need more than 68 languages.
Your CMS is on their plugin list and you’d rather install a plugin than configure anything.
You want to buy human translation as a paid service. Both tools translate automatically, but ConveyThis also resells a partnered agency, so you can commission and pay for professional translation in the same dashboard.

Proxylang makes sense if:

You’re on a modern JavaScript framework and need server-side indexing, so your visitors get a fast page and Google still gets fully translated HTML it can rank.
You want multilingual Live Chat included, rather than as a second subscription from another vendor.
You run more than one site. Proxylang gives you two on Start, five on Pro, and stops counting entirely from Business up. ConveyThis caps every plan it sells, at 50 even on the $960 tier.
You want a human to check the AI’s work without paying an agency to redo it. Proxylang translates your whole site on its own; if you then want a native speaker to polish a page, invite them by email into the live editor, scoped to the languages they own. They don’t need a Proxylang plan, and there’s no reseller markup on their time.
You have text baked into banners, menus, or product graphics and want it translated without rebuilding each image by hand.
You’re translating between Asian and Western languages and want the highest quality, most natural sounding translations.
You want reverse search translation, so visitors can search your site in their own language.
You’re selling into a market where Google isn’t the search engine that matters:
- South Korea, where Naver carries a large share of commercial search
- Russia, where Yandex leads
You want the visual editor, the glossary, and do-not-translate rules from day one without paying for them. ConveyThis puts its editor behind a paid plan; Proxylang’s free tier has the same editing tools as the $699 one.

The bottom line

ConveyThis competes on breadth. More languages on the menu, more CMS plugins, and translators you can buy from the dashboard. If you need 40 languages on one site and want to pay as little as possible for the words, it’s a reasonable pick.

Proxylang competes on what comes with those words. Server-side indexing that gets your translated pages ranked, while visitors still get a page that loads instantly. Multilingual Live Chat from $39 up, with no second vendor to sign up for. Automatic image translation. Reverse search translation. An engine tuned for the Asian and Western pairs most tools handle worst. A ConveyThis plan buys translated words. A Proxylang plan buys translated words, the SEO tooling to get them indexed, and a translated chat channel on top.

The tradeoff is honest: below $400 a month ConveyThis lists more raw words per dollar, and it has three times the languages on the menu. Past that, Proxylang pulls ahead on words, drops the page-view cap, and stops counting your sites altogether.

Both have free plans. Run both on your own site, look at the output in the languages you actually sell in, and price out what a real month costs you.
