Teams usually look for Gun.io alternatives for one of three reasons: a custom package instead of a rate card, a wish for engineers in European timezones, or the terms for hiring a contractor full-time. Below are five other ways to hire senior engineers, each with its hire-out term. Gun.io comes first, described from its own pages, so you can judge the fit before you leave.
Gun.io alternatives compared
The ranking follows the reasons buyers leave: European timezones and GDPR first, then published conversion terms, then how much screening you carry yourself. Gun.io isn't in the table. It's described in the next section. Where a cell says "Not stated on its site", we looked and found nothing, and we'd rather leave a gap than guess.
| Rank | Platform | Best for | Geography | Vetting | Hire-out terms |
|---|---|---|---|---|---|
| 1 | HighCircl | Senior engineers in European timezones with GDPR handled | 7 European countries | Four stages run by senior engineers | 18% of annual gross, disclosed from the start |
| 2 | Lemon.io | Project work with a 160-hour minimum | Europe-based developers (Poland, Ukraine listed) | Not stated on its site | Two placement fees across its policy and terms |
| 3 | Toptal | Teams that want a trial of up to two weeks | Not stated on its site | Says it accepts fewer than 3% of applicants | No direct-hire fee found on its developer page |
| 4 | Arc.dev | Teams that will screen a large pool themselves | Worldwide pool (20M+ candidates, per its pricing page) | Not stated on its site | 20% of annual salary for full-time hires |
| 5 | Upwork | Teams with their own hiring process | Not stated on its site | Not stated on its site | Fees change; check the current client terms |
What Gun.io is today, and what it charges
Gun.io was founded in 2013, according to its about page, and describes itself as a delivery-first Engineering Guild. Its homepage adds that it handles vetting and multi-currency payroll in more than 100 countries, and lists regions including South America, Asia and Europe. You deal with a vetted bench, not an open board.
Its strengths are real. Its FAQ says about 1,000 people apply each month and roughly 100 are approved, so around one in ten. Developers are paid the rate they request, weekly, on net-30 terms. If you want one vendor to run contracts and payroll across borders, that's a coherent offer.
Pricing is the part you can't read in advance. The archived pricing page says Gun.io has no standard rates and builds a custom package for each client, though the FAQ says each developer's rate is shown on their profile. We don't print a Gun.io rate here, because Gun.io doesn't publish a standard one.
Why teams look for Gun.io alternatives
Quotes instead of a rate card
Custom packages suit some buyers. If you're setting five vendors against one budget line, though, a vendor with no standard rate is the hardest to compare, and you end up comparing a quote against rate cards. For reference, HighCircl publishes €45-105/hr ($50-115/hr) for senior engineers, with a 20% capped margin on top of what the engineer earns. That's the kind of number you can put in a spreadsheet before anyone books a call.
The two-year non-solicit and 20% placement fee
This is the term buyers tend to miss. Gun.io's FAQ says clients sign a two-year non-solicitation agreement, and that hiring a contractor permanently costs 20% of the negotiated first-year salary. As arithmetic, a €90,000 salary (illustrative, not a Gun.io price) means a €18,000 fee on top of the contractor spend. Whether that's fair depends on how much sourcing work the vendor did for you. Decide before the first invoice, not at month eight when you've already decided you want the person.
The alternatives
1. HighCircl
HighCircl places senior engineers from Poland, Hungary, Slovakia, Serbia, Slovenia, Romania and Spain, across React, Node.js, Python, iOS, Android, Flutter, Go and DevOps. About 1 in 10 applicants pass four stages run by senior engineers, and you get a shortlist of three to five candidates in 72 hours. There's no subscription, no recruitment fee and no minimum hours. A deposit of one month's estimated cost is applied to your first invoice.
It doesn't cover designers, product managers, finance experts or US-timezone-only roles, so if you need those it isn't the right fit. Hire-out term: an 18% buyout on annual gross, disclosed upfront, against an industry norm of 20-25%. If an engagement isn't working, HighCircl replaces the engineer at no additional recruitment cost.
2. Lemon.io
Lemon.io's commitment is the first thing to price. Its FAQ states a 160-hour minimum project size, which is one month full-time. Its terms also describe a separate LemonHire service with a four-week trial capped at 160 hours plus a $2,000 management fee.
The placement fee depends on which document you read: $14,000 in its placement-fee policy and $20,000 under LemonHire in its terms of use. Ask which one applies to your engagement before you sign. Our fuller comparison is in Lemon.io alternatives.
It fits project work where you can commit a month of hours up front. If you want to hire the person within a few months, price both fees first.
3. Toptal
Toptal's developer hiring page describes a trial period of up to two weeks and says fewer than 3% of applicants make the cut. That combination is the case for it: a short, defined window to judge a developer before you commit. We found no direct-hire fee on that page, so get the conversion cost in writing before the trial starts, not after.
Toptal isn't the only route to a short trial, and a trial doesn't answer the question of what you pay if the person is good. For other routes, see Toptal alternatives.
4. Arc.dev
Arc advertises a worldwide pool of 20M+ candidates, per its pricing page, which also shows 20% of the annual salary as the fee for full-time hires. That's the same percentage as Gun.io's, so Arc isn't the answer if the conversion fee is your reason for leaving. It's a better fit if you have a technical lead who will screen a large pool and wants volume to choose from.
5. Upwork
Upwork's fees change, so we won't quote them here. Read Upwork's current client terms on the day you sign rather than trusting an old comparison, this one included. It suits a team that already runs its own hiring process and wants reach, not a vendor who filters for you.
How to choose
Three questions sort most buyers.
Do your engineers need to overlap with European working hours, and will someone ask about GDPR? If yes, start with HighCircl and compare countries before you compare vendors. Our guide to the best countries in Europe to hire developers covers that part.
Do you want a trial before committing? Toptal states a trial of up to two weeks. Lemon.io's LemonHire describes a four-week trial capped at 160 hours, with a $2,000 management fee. HighCircl has no minimum hours, so there's no month to sit through, and if the engagement isn't working it replaces the engineer.
Will you screen candidates yourself? If yes, Arc.dev or Upwork give you the widest pool. If you want the vendor to filter before names reach you, pay for a vetted network and ask what the filter is.
What this means for your vendor choice
The deciding factor for most CTOs isn't the day-one rate. It's what happens when a contractor turns out to be the person you want on payroll. Write down three numbers before you sign with any vendor: the conversion fee, how long a non-solicit lasts, and the minimum you commit to before the trial ends. Gun.io's answers are 20% of first-year salary and two years. Arc's fee is also 20%. Lemon.io's depends on the document, $14,000 or $20,000. HighCircl's is 18%.
If you expect to convert at least one contractor in the next year, treat that fee as part of the budget and compare vendors on total cost, not hourly rate. If you never plan to convert, the non-solicit matters less and rate transparency matters more. That's our judgment, not a rule. Before you book calls, check published HighCircl rates so you have a figure to hold other quotes against.
Hiring senior European engineers through HighCircl
HighCircl places senior engineers from seven European countries: Poland, Hungary, Slovakia, Serbia, Slovenia, Romania and Spain. Rates run €45-105/hr ($50-115/hr), with a 20% capped margin on top of engineer pay. You get a shortlist of three to five vetted candidates in 72 hours, with no subscription, no recruitment fee and no minimum hours. Permanent-hire buyout is 18% of annual gross. See hiring senior engineers through HighCircl for stacks and how matching works.
FAQ
Is Gun.io a marketplace?
Not in the open-board sense. Its FAQ says roughly one in ten applicants are approved, and it calls itself a delivery-first Engineering Guild that handles vetting and multi-currency payroll. If you want an open marketplace instead, Upwork is the one in this list.
What does Gun.io cost?
Gun.io states no standard rates and builds a custom package, though its FAQ says each developer's rate is shown on their profile. Ask for the package total alongside the profile rates.
Does Gun.io charge a fee to hire a contractor full-time?
Yes. Its FAQ states a placement fee of 20% of the negotiated first-year salary, and clients sign a two-year non-solicitation agreement. Compare that against HighCircl's 18% buyout and Arc.dev's 20% full-time fee before you commit.
Is there a Gun.io alternative with European timezones?
HighCircl covers Poland, Hungary, Slovakia, Serbia, Slovenia, Romania and Spain, and is GDPR native. Lemon.io lists Europe-based developers too, including Poland and Ukraine.
Is there a free Gun.io alternative?
No vendor here is free. Each one charges through rates, placement fees or both. HighCircl charges no subscription or recruitment fee, only the rate with its capped margin.
