Let me save you about 47 hours of research and trial accounts. If you’re trying to pick between Waalaxy and SBL.so for your LinkedIn automation, you’ve probably noticed something weird. Both claim to automate your outreach. Both have nice dashboards. Both promise to save you time.
But here’s what nobody tells you… they’re fundamentally different products solving different problems. And picking the wrong one could mean months of wasted effort.
I’ve tested both extensively. Broke a few accounts along the way (sorry, test profiles). And I think I finally understand who each tool is actually built for. So let me break it down for you.
The Core Difference You Need to Understand First
Waalaxy is a solid sequence-based automation tool. You build workflows. If connection accepted, send this message. If no reply in 3 days, send follow-up. Classic stuff that’s been around for years.
SBL.so is something different. It’s an AI SDR that actually handles conversations. Not just sending messages, but replying to your prospects, handling objections, and pushing toward booked calls.
That’s not a small difference. That’s the difference between “automation” and “having an employee who never sleeps.”
Most LinkedIn automation tools stop the moment someone replies. Then you’re back to manually managing your inbox. SBL doesn’t stop there. It keeps going.
What Waalaxy Actually Does Well
Look, I’m not here to trash Waalaxy. It’s a legitimate tool that thousands of people use. Here’s where it shines:
- Simple sequence building with a visual editor that’s pretty intuitive
- Email + LinkedIn combo for multi-channel sequences
- CRM integrations that work reasonably well
- Affordable entry point for solo founders just getting started
- LinkedIn profile visits and auto-likes as part of warming sequences
If you want a tool that sends connection requests and a few follow-up messages automatically, Waalaxy does that. It’s reliable. It’s been around since 2019. It works.
But here’s my problem with it…
Where Waalaxy Falls Short in 2026
The game has changed. In 2026, your prospects are getting 15+ automated connection requests per week. They can smell a template from miles away.
Waalaxy can’t chat. Once someone replies, you’re on your own. Managing those conversations manually. Which means you either hire SDRs or you spend your evenings in LinkedIn’s inbox.
I tried scaling Waalaxy to 5 accounts once. Disaster. Jumping between profiles, losing track of conversations, accidentally sending the wrong follow-up because I forgot which account was which. Never again.
Also, their AI features? Mostly just GPT slapped on top for message generation. Not bad for writing templates. But not actual conversational AI.
What SBL.so Brings to the Table
Here’s where I might sound biased. But I genuinely think SBL.so has figured out something the other LinkedIn messaging automation tools haven’t.
The entire system is built around one premise: real conversations convert better than sequences.
So they built AI that actually talks to your prospects. Not if-else chatbot logic. Actual contextual responses trained on persuasion principles and sales psychology.
You set your goal (book demos, qualify leads, whatever). The AI handles the rest. Connection request. First message. Follow-up. And then when they reply… it keeps chatting. Handles objections. Asks qualifying questions. Pushes toward booking.
You can jump in anytime. But you don’t have to.
Feature Comparison: Waalaxy vs SBL.so
Let me break this down properly so you can see it clearly:
LinkedIn Automation Capabilities
- Waalaxy: Connection requests, profile visits, auto-likes, message sequences, InMails
- SBL.so: All of the above PLUS AI-powered chat replies, voice note automation, file/image sending in conversations
AI Features
- Waalaxy: AI message writer (template generation). No conversational AI.
- SBL.so: Full conversational AI that handles objections, qualifies leads, and pushes toward your goals. Learns from your manual interventions.
Multi-Channel
- Waalaxy: LinkedIn + Email integration
- SBL.so: LinkedIn + WhatsApp with email coming soon
Account Management
- Waalaxy: One account per subscription. Team plans available but pricey.
- SBL.so: Unlimited accounts in one workspace. All chats in unified inbox. Auto-rotation when one account hits limits.
Scaling Potential
- Waalaxy: Limited by your ability to manage multiple separate accounts
- SBL.so: Built for scale. 50 accounts = 40,000+ reach-outs monthly. Email-level scalability on LinkedIn.
Pricing Breakdown: Which One is Actually Cheaper?
This is where it gets interesting. And honestly, kinda complicated.
Waalaxy Pricing (2026):
- Free tier: Very limited (basic sequences only)
- Pro: Around €60/month per seat
- Business: Around €100/month per seat
- Team plans scale linearly. 5 people = 5x the cost.
SBL.so Pricing:
- Free trial to get started
- Plans from $99/month
Here’s the math that matters. If you want to run 10 LinkedIn accounts on Waalaxy, you’re looking at €600-1000/month. On SBL? $99 = starts $99/month. Plus you get AI chat handling included.
For agencies and teams doing serious outreach, SBL is significantly cheaper at scale.
Can Waalaxy or SBL.so Actually Book Meetings Automatically?
This is the question everyone asks. And the honest answer is complicated.
Waalaxy: No. It sends messages. If someone says “sure, let’s chat,” you still need to manually jump in, send your Calendly link, and close. Every. Single. Time.
SBL.so: Yes, actually. The AI is trained to push toward your goal. When a prospect shows interest, it handles the back-and-forth, qualifies them, and books the call. You just take the meeting.
I know that sounds too good to be true. But I’ve seen it work. The AI doesn’t always get it right, of course. Some conversations need human intervention. But SBL has a “Human Intervention Required” flag for those cases. You handle it once, and the AI learns from it.
Which Tool is Safer for Your LinkedIn Account?
Both tools claim to be “safe.” But here’s reality…
LinkedIn restrictions usually happen because of two things: going over limits and sending obviously automated messages.
Waalaxy has decent safety features. Activity limits, random delays, working hours simulation. Standard stuff.
SBL takes it further with:
- Automatic account rotation (hit a limit on one account, system switches to another)
- Up to 75 new connections per day safely
- 200 messages to first-degree connections per day
- Human-like conversation patterns that don’t trigger LinkedIn’s spam detection
I’ve never had an account restricted using SBL. Waalaxy? Lost one test account in 2024 coz I pushed the limits too hard. My fault, but still.
Is Waalaxy Better for Lead Generation?
Waalaxy has decent lead scraping from LinkedIn searches. You can import from Sales Navigator URLs. Standard features.
SBL has a Lead Generation Agent that’s a bit smarter. You tell it your ICP, it finds leads matching that criteria. Not just scraping based on job titles, but actually analyzing profiles.
Both integrate with Sales Navigator. Both let you import lists.
For advanced lead enrichment, you’d probably want to pair either tool with dedicated B2B data enrichment tools.
Which LinkedIn Automation Tool is Better for Agencies?
If you’re running an agency and managing multiple client campaigns… this is where the choice becomes obvious.
Waalaxy:
- Separate subscription per client account
- No unified inbox across clients
- Manual management of each campaign
- Costs add up fast
SBL.so:
- Unlimited workspaces for different clients
- All chats in one unified inbox
- Team members can be assigned to specific workspaces
- SBL’s Fractional SDR Network: verified LinkedIn users who can run outreach on behalf of clients
That last point is wild. If your client doesn’t have enough LinkedIn accounts, SBL has a network of real people who’ll let you use their profiles for outreach. Starting at $35/month per affiliate. It’s like having an army of SDRs on demand.
For digital agencies doing LinkedIn automation, SBL is built for this exact use case.
What About Comment to DM Automation?
You’ve seen those posts. “Comment ‘PDF’ and I’ll send you the guide!” Engagement farming that actually works.
Waalaxy: Doesn’t have this.
SBL.so: Has Comment to DM automation built in. Set a keyword (or even just “positive comments”), paste your post URL, and it handles the rest. Even works on competitor posts. Shhh.
Does Waalaxy Have Voice Notes or Image Sending?
This might seem like a small feature. But voice notes get crazy engagement. Way higher than text.
Waalaxy: Text messages only.
SBL.so: You can send PDFs, images, files, and… voice notes that sound like you. Clone your voice with a 10-30 second sample. Send thousands of personalized voice messages without recording a single one.
For sending images in LinkedIn automation, SBL is one of the few tools that does it properly.
Common Questions Answered: Waalaxy vs SBL.so
Can I run Waalaxy and SBL.so together?
Technically yes, but I wouldn’t. Running two automation tools on the same LinkedIn account is asking for a restriction. Pick one. If you want basic sequences, Waalaxy. If you want AI conversations, SBL.
Which tool has better analytics?
Waalaxy has standard campaign metrics. Opens, replies, acceptance rates.
SBL goes deeper with sentiment analysis, lead interest scoring, and qualitative insights from every conversation. It tells you what’s working in your outreach and what’s not based on actual conversation data.
Can either tool integrate with my CRM?
Both integrate with major CRMs. SBL pushes entire chat data in real-time which is more useful for sales context.
Which is better for job seekers?
Honestly? Either works. But SBL’s conversational AI might be overkill if you’re just sending connection requests to recruiters. Waalaxy’s cheaper tier could work fine for basic networking.
What if I’m just starting with LinkedIn automation?
Start with SBL’s free tier. Get familiar with how LinkedIn automation works. Scale from there.
Does Waalaxy work with Recruiter Lite?
Yes, basic integration. SBL also integrates with Sales Navigator and Recruiter.
The Verdict: Who Should Use What
Use Waalaxy if:
- You just want basic sequence automation
- You’re comfortable managing replies manually
- You need email + LinkedIn in one tool specifically
- Budget is super tight and you’re only running 1-2 accounts
- You don’t mind hiring SDRs to handle conversations
Use SBL.so if:
- You want AI to handle conversations, not just send messages
- You’re scaling to multiple accounts (5+)
- You’re an agency managing client campaigns
- You want meetings booked without manual inbox management
- You need LinkedIn + WhatsApp together
- You want email-level scalability on LinkedIn
Look, if you’ve read this Dripify comparison (and the others we’ve done, like SBL vs HeyReach), you’ll notice a pattern. Most LinkedIn tools do the same basic stuff. Waalaxy included.
SBL is doing something genuinely different. It’s not for everyone. If you just want to send connection requests and forget about it, simpler tools exist.
But if you actually want AI-powered sales automation that handles the messy part, the conversations, the objections, the follow-ups, the booking… that’s what SBL was built for.
Make your choice. But at least now you know what you’re choosing between.
