Who should choose which
Choose Octopus CRM if
- you want the lowest cost per LinkedIn account and will write every message yourself.
- you are one seller who runs a connect and message sequence from your own browser.
- you want a simple personal lead list rather than a full sales tool.
- you manage 20 or more accounts and want to ask about agency pricing.
Choose Sellinger if
- you want the agent to write every message and answer each reply in the thread.
- you do not want outreach to depend on a browser that stays open on one computer.
- you want email, WhatsApp, Instagram replies and live chat beside LinkedIn, in one conversation history.
- you want a real CRM with deals, a contact database and intent signals in the product.
Monthly cost for one subscription, five and twenty five
On price Octopus is far lower than Sellinger. Each subscription is tied to one LinkedIn account, and a separate subscription is needed for each. Sellinger prices per agent, with the writing and the replies included.
All prices are monthly list prices in US dollars on the Monthly tab, using the Pro plan for the Octopus column. Octopus lists special pricing by contact for 20 or more accounts, so the last row is the list price.
| LinkedIn accounts | Octopus CRM, Pro | Sellinger LinkedIn agent |
|---|---|---|
| 1 | $14.99 | $198 |
| 5 | $74.95 (5 accounts at $14.99) | $890 (5 agents at $178) |
| 25 | $374.75 (25 accounts at $14.99) | $4,200 (25 agents at $168) |
A browser extension against a hosted login
Octopus acts through your own LinkedIn session in your own browser, so the browser has to be open and the computer on. It has no cloud mode. Its own pages state daily caps inconsistently, from 100 connection requests and 200 messages a day on one page to a limit of 250 total actions a day on another.
Sellinger logs in through a hosted flow with no password kept, and an account can go through your own proxy. The starting limits are 20 invitations a day and 150 a week, with quiet hours at night. Whatever the tool, LinkedIn may still restrict an account, and nobody can promise it will not.
What the low price covers
Octopus covers connection requests, messages to first level connections, profile visits and skill endorsements, with an option that sends requests by email to get past the weekly invite limit. It lists no AI writing, no inbox and no email outreach channel.
Sellinger is a different scope: an agent that researches each person, writes in the right channel, answers replies and books the meeting. If you only need a sequence and have the time to write it, that scope may be more than you need.
Switching between Octopus CRM and Sellinger
Each Octopus subscription belongs to one LinkedIn account, so plan the move around accounts.
- Choose a LinkedIn account without an Octopus subscription and connect it to Sellinger.
- Export your leads and funnel stages from Octopus and import them into Sellinger.
- Tell the agent what you sell, read what it drafts for the first few people and widen only after that.
- Give it a few weeks and compare replies and booked meetings per account before moving more.
- Octopus lets you cancel any time from the billing page, so you can run both for a short test.
- Pause the Octopus campaign first. Two tools acting on one LinkedIn account can trigger limits.
