In the Lemon.io vs Arc.dev comparison, Lemon.io is the pre-vetted, prepaid option: a 160-hour minimum for short engagements and a $20,000 placement fee in its Terms. Arc.dev is the vetted marketplace with freelancer-set rates, 20% on full-time hires and a risk-free trial of up to two weeks. Lemon.io's own pages use the 160-hour figure in two different ways, and we flag it below.
One disclosure: HighCircl is also a vendor, so we're a third option. Every Lemon.io and Arc.dev fact here comes from lemon.io or arc.dev, not from other vendors' write-ups.
The short answer
Pick Lemon.io if you want a small, pre-vetted shortlist fast, can commit to at least 160 hours, and plan to keep the engineer on the platform. If you plan to hire them permanently, price the $20,000 fee first.
Pick Arc.dev if you want volume, a risk-free trial of up to two weeks and are ready to screen candidates yourself. Budget for a wide rate range, because freelancers set their own.
Pick neither on the strength of a comparison page, ours included. Both fee structures have gaps that only a written quote closes.
What each platform sells today
Lemon.io
Lemon.io is a pre-vetted, prepaid marketplace. Its vetting page says it accepts 1.2% of applicants. Billing is prepaid, and Lemon.io's pricing page says there are "no upfront recruitment or setup fees" (it also describes the model as a "prepaid subscription").
Arc.dev
Arc.dev sells both freelance developers and full-time hires. Its how-it-works page puts the average full-time hire at about 14 days.
On pool size, Arc's pricing page says "20M+ candidates" and doesn't say how many have passed vetting or are available. If pool size matters to your decision, ask Arc how many vetted developers are active and available in your stack.

How the vetting differs
Lemon.io describes four stages: a pre-screen, a recruiter interview, a technical interview and a final listing. Lemon.io's vetting documentation shows about 37%, 17%, 7% and 1% passing each stage, without saying whether each figure is a share of all applicants or of the previous stage. Arc.dev's four steps start with profile screening (55%), a communication assessment (14%) and a technical interview (2%), per its how-it-works page.
Which filters harder? Both land in the low single digits, and Lemon.io's 1.2% headline is lower than Arc's 2%. But we can't tell that those percentages measure the same thing. One could be a share of applicants, the other a share of those who reached a stage. Our judgment: don't choose on the gap between 1.2% and 2%. Ask each vendor what a candidate actually does in the technical interview, who reviews it, and whether you can see the result.
Arc.dev's first filter is a profile screen (55%), and Lemon.io's is a pre-screen (about 37%). We didn't find how long the technical test runs on either vendor's pages.
What each costs: the terms that surprise buyers
Lemon.io
The pricing page says payment is "typically made one month in advance"; the billing doc says one billing cycle (monthly or weekly) is prepaid at its start, and unused hours roll over. Lemon.io's billing document also states the rate as "$60 to $90/hr". Quote the rate you're given in writing.
The 160-hour figure also appears twice with different meanings. The pricing page answers "Yes, 160 hours" to the minimum question, which it equates to one month full-time or two months part-time. Lemon.io's Terms of use (Section 12.1) use 160 hours as a cap on trial hours. Both can be true, but you should confirm which one applies to your engagement.
The big number sits in the Terms. The placement fee is $20,000. A hire after the trial pays $20,000 less the $2,000 management fee, so $18,000 net. A developer hired off-platform triggers the full $20,000, due within five days (Section 8).
Arc.dev
Freelance rates are set by freelancers at "$15 - $110+" per hour, per Arc's pricing page. Full-time hires cost 20% of annual salary, so get the fee for your hire stated in an order form.
What will month one and a permanent hire cost? On Lemon.io, a month of one full-time engineer at $60-90/hr is roughly 160 hours, so $9,600-14,400 prepaid before any $2,000 trial fee, and $20,000 less any $2,000 trial fee already paid if you keep them. That arithmetic is ours, from the vendor's rates. On Arc.dev, the freelance month depends on whom you pick, and a $150,000 salary hire carries a $30,000 fee at 20%.
Trials and replacement
Lemon.io's LemonHire trial runs four weeks. You pay the developer's hourly rate plus the $2,000 flat management fee, and the Terms cap it at 160 hours. After the trial there's a 60-day guarantee with free replacement, and a full refund if none is found within 30 days (Sections 12.1 and 12.4).
Arc.dev offers a "risk-free trial period of up to two weeks" on freelance engagements, and a free re-match "during the first 3 months" if you're dissatisfied. Neither of those lines says what happens to hours you've already paid for, so ask.
On paper, Lemon.io's protection is longer and more formal. Arc's trial is shorter, but it carries no management fee we could find. Judgment: if you hire permanently, Lemon.io's 60-day guarantee matters more than the trial, since by then you've already paid.
Where Lemon.io's own pages disagree
Most of the pages we read are written by vendors selling something. Lemon.io's own pages disagree with each other on one point.
- The 160 hours: a minimum on the pricing page, a trial-hours cap in the Terms.
That doesn't make the pages dishonest. It means vendor terms change and nobody rechecks them. Read the vendor's current page and keep a dated copy.
What EU buyers need to ask
We couldn't find a GDPR or data-processing statement on the vendor pages we read, so treat both as "ask the vendor". Before an engineer touches production data, request a data processing agreement, the transfer mechanism, and the country each engineer works from.
Put timezone overlap in the brief as a hard number, such as four shared hours, and ask for the country of every candidate before interviews. If neither platform fits, the wider list of Lemon.io alternatives and our look at where AI matching falls short on Arc cover other routes, and options beyond the two platforms, such as Gun.io compares another vendor's terms.
What this means for your vendor choice
For one to three senior hires, the choice comes down to cost shape and protection. Our judgment: pick Lemon.io if you want pre-vetted, prepaid matches, can commit to 160 hours and will keep the engineer on the platform. Pick Arc.dev if you want volume and a risk-free trial of up to two weeks and are ready to screen yourself.
Before you sign with either, get these in writing:
- The hourly rate, and which of the vendor's published ranges it falls in
- The minimum commitment and what ending early costs
- The trial length, its fees and any hour cap
- The replacement window
- The conversion or placement fee for a permanent hire
Our guide on how to evaluate a nearshore vendor before signing turns that list into questions for a sales call.

FAQ
Is Lemon.io cheaper than Arc.dev?
We can't say. Arc's range is wider and reaches lower ($15-110+), Lemon.io's billing doc says $60-90 with a 160-hour minimum and a $2,000 trial fee. Compare written quotes for the same role.
Is Arc.dev legit?
Arc.dev publishes a four-step vetting process, a risk-free trial of up to two weeks and a 3-month re-match, all on its own pages. That tells you what it promises, not how it performs. Check the order form for those promises.
Is Lemon.io legit?
Lemon.io publishes a 1.2% acceptance rate, four vetting stages and detailed terms, including the trial fee, replacement and placement fee. Those are vendor-published facts, not an audit. We aren't giving a verdict beyond that.
Does Lemon.io have a minimum?
Yes, for short engagements: its pricing page says "Yes, 160 hours". The Terms use the same figure as the cap on trial hours. Ask which applies before you sign.
What is the Arc.dev placement fee?
Arc's pricing page lists 20% of annual salary for full-time hires. Confirm the fee for your hire in writing.
How does Arc.dev compare with Toptal?
We haven't compared them head to head. Arc publishes a freelancer rate range of $15-110+ and a four-step vetting process, so you can hold any Toptal quote against those.
