Serposcope
Free self-hosted rank tracker, now marked unsupported by its developer
Which one is for you
Pick Bisibility if
- Fits if you're a developer who wants to host rank tracking yourself and keep the data
- Works for people who already pay DataForSEO or SerpApi and want an app on top
Look elsewhere if
- Skip it if you want the data included in the price, as checks run on your own DataForSEO or SerpApi account, or on credits
- Watch out: credits cost the provider's rate plus 30%, come in $5 to $100 packs and are non-refundable
- Too light for Maps grids, research, backlinks or AI tracking on SerpApi alone, which covers Google rankings and the Local Pack only
- Tight if you run lots of checks on Cloud, which has a weekly processing limit shown only in the app
- Not for you if you need rankings beyond Google, as no other search engine is on record
Pick Serposcope if
- Fits if you want ranking data kept on your own machine rather than in a vendor's cloud
- Works for technical users who already pay for proxies or a SERP API
Look elsewhere if
- Skip it if you want software that's kept up: it's marked unsupported, may not work, and 3.5 from January 2025 is the last release
- Watch out: Google checks need paid add-ons, since Scraping Ant's free plan doesn't work with Google and captcha solvers cost money
- Not for you if setting login protection by hand in a config file sounds like hard work
- Tight if you have Serposcope 2 data, since it can't be moved into version 3
- Watch out: the Windows and Mac installers aren't signed, so both systems warn before installing
How we grade them
| 2.2GPABisibilityFair | 2.2GPASerposcopeFair | |
|---|---|---|
| Value for money | CCloud is $3 a month, but no search data is included. Bisibility puts 100 keywords checked daily at about $12 a month in DataForSEO usage, so roughly $15 all in, between this category's cheaper quarter ($10) and middle ($19.99). Self-hosting is free but needs a server. | BThe program is free, with no paid edition. Reliable checks need paid help, though: Scraping Ant's free plan doesn't work with Google, and the captcha solvers it supports are paid services, so running it well isn't really free. |
| Free plan and trial | CSelf-hosting the full app costs nothing, and Cloud has a 7-day trial with no card. But every check still needs paid search data from DataForSEO or SerpApi, or credits bought in $5 to $100 packs. | AVersion 3.5 is a free download for Windows, Mac and Linux, with no account and no paid edition. Everything it does comes without paying Serposcope anything. |
| Features | CGoogle rankings by location and device with a saved results page per check, AI answer tracking, keyword research, backlinks, a sampled site audit and Search Console history past 16 months. The gaps: rankings are Google only, and most extras need DataForSEO. | DRank tracking with saved result pages, a backlink watch and a local database you can query. But it needs proxies, captcha solvers or a SERP API to fetch Google reliably, and the developer says it may not work at all now. |
| Ease of use | CNo rating on record. Cloud saves you hosting it, but you still connect a DataForSEO or SerpApi account or buy credits, and lookups are priced one by one, so there's setup before the first check. | DNo rating on record. You install it yourself, set login protection by hand in a config file and wire up proxies or captcha solvers, and both Windows and Mac warn before installing it. |
| Platforms and integrations | BWeb only, with no desktop or phone app. It links to DataForSEO, SerpApi, Search Console, GA4 and Plausible, and has MCP for Claude, ChatGPT, Cursor and Codex, a REST API, a CLI and SDKs. | CA program for Windows, Mac and Linux that opens in your browser, linked only to scraping and captcha services. No phone app, and the API isn't documented. |

Worth knowing
Bisibility
- Neither Cloud nor self-hosting includes search data: you need a DataForSEO or SerpApi account, or credits at provider cost plus 30%.
- Bisibility estimates about $12 a month in DataForSEO usage for 100 keywords checked daily to the top 20, in one location on one device.
- Credits come in $5 to $100 packs that never expire and are non-refundable; Cloud also has a weekly processing limit shown in the app.
- Maps grid, keyword research, backlinks and AI tracking need DataForSEO; SerpApi covers Google rankings and the Local Pack only.
Serposcope
- The download section says Serposcope is no longer supported and may not work; the last release, 3.5, is dated January 2025.
- Reliable scraping needs paid add-ons: Scraping Ant's free plan does not work with Google, and captcha solvers are paid services.
- Login protection must be set by hand in a config file, and Serposcope 2 data cannot be moved into version 3.
- The Windows and Mac installers are not signed with paid certificates, so both systems warn before installing.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
