BacklinkOS vs GuestPostCRM (2026): which should you pick?

Pick BacklinkOS if

• Fits if you trade links with other site owners and track the swaps in spreadsheets now
• Works for keeping bought links and exchanged links in one list

Look elsewhere if

• Tight if you're staying free: the 50 link checks and 50 metric refreshes are one-time, with 10 domains and 40 partner matches
• Not for you if you want links checked without lifting a finger, as monitoring starts at Pro and runs monthly
• Pricey if you need weekly checks, which mean Pro Max at $63 a month billed annually ($79 monthly)
• Skip it if you need a full backlink audit or outreach emails, as it only tracks the links you log
• Watch out: Slack is the only integration named, and links come in by CSV import

Pick GuestPostCRM if

• Fits if you sell or buy guest posts and keep publishers, prices and orders in spreadsheets
• Works for small agencies, as Starter includes 3 users

Look elsewhere if

• Tight if your inbox is busy: actions cost 1 to 11 or more credits, and the free plan has 2,000 credits and 1 user
• Pricey if you want Moz metrics or API automation, which start at $39 and $69 a month
• Watch out: white-label setup is $500 once, from Professional, and extra users are $5 a month each
• Not for you if your mail isn't in Gmail, as Gmail is the email connection named
• Skip it if you need sites to pitch, as it manages deals rather than finding prospects

BacklinkOS

• The free plan's 50 link checks and 50 metric refreshes are one-time allowances that do not renew.
• Automated monitoring starts at Pro and runs only monthly there; weekly checks need Pro Max at $63 a month billed annually.
• It is built around link exchanges and partners; it does not report a site's full backlink profile.
• Slack is the only integration named; collaborators and links can be brought in by CSV import.

GuestPostCRM

• Every automated action uses credits, from 1 for a label move to 11 or more for processing an order, so busy inboxes use up allowances fast.
• The email connection named is Gmail; sign-in is with a Google or Microsoft account.
• Moz metrics start at Growth ($39 a month) and full API automation at Professional ($69 a month).
• White-label setup costs $500 once on Professional and above, and extra users are $5 a month each.
