liblab is an SDK generation platform that helps companies create high-quality, developer-friendly SDKs for their APIs in multiple languages. Our technology automates the process of generating, maintaining, and optimizing SDKs, ensuring compliance and best practices while saving engineering teams time. We work with fintech, telecommunications, and other industries that rely on robust API ecosystems. Backed by $50 million in funding, liblab is focused on making SDK development seamless and scalable.
Apollo.io
liblabWe use Apollo with our Sales and BDR team to manage our cold outreach. The strength of the platform is the sequences and cadences that you can set up. Compared to other tools we have used in the past like Salesloft the UI is much easier to navigate. The main limitation is that the quality of data isn't as vast and often I can find prospects on Linkedin but not in Apollo.
Based on our record, Apollo.io seems to be a lot more popular than liblab. While we know about 69 links to Apollo.io, we've tracked only 5 mentions of liblab.

Personal email domains destroy this. Clearbit's Enrichment API returns a null company when it hits gmail.com. Apollo routes personal domains straight to a consumer bucket and skips B2B fields entirely. Even PDL's /person/enrich endpoint โ the most permissive of the major providers โ gives you around 32% hit rate on Gmail addresses versus 74% on corporate domains. I measured this across 6,200 signups for a... - Source: dev.to / about 2 months ago
A few things worth flagging: PDL beats Clearbit's historical rates for US and Western European companies, but drops to ~52% match rate for Japan and South Korea specifically. Apollo underperforms on raw company matching but returns significantly more contacts per domain in Prospector-style queries than Clearbit's Prospector ever did โ the tradeoff is more stale titles in the result set. Hunter.io is fast and cheap... - Source: dev.to / 2 months ago
One thing comparison guides consistently get wrong: Clay is not an enrichment API. It's a waterfall orchestration tool that calls People Data Labs, Apollo, Clearbit, and others in sequence for you. It's useful, but it adds 2โ8 seconds of latency per row in my runs and costs more per match than going direct. For a CRM webhook flow where you need sub-second enrichment calls, Clay is the wrong layer to hit first. - Source: dev.to / 3 months ago
Last year I ran the same LinkedIn Sales Navigator export through three enrichment APIs. Apollo matched 61% of the emails. Hunter.io matched 54%. An OSINT-first pipeline I'd built in n8n โ pulling from public sources before hitting any paid API โ matched 79% and cost roughly $0.003 per contact. The delta wasn't magic. It was sequence. - Source: dev.to / 3 months ago
Despite having its LinkedIn Page removed in 2025, Apollo remains a functional enrichment and outreach platform with 275M+ contacts. The free tier includes 10,000 credits and the $49/month basic plan is the cheapest entry point for a combined enrichment-plus-sequencing workflow. Apollo's data collection methods have attracted LinkedIn's attention, but the product continues to operate. The risk I'd assign it:... - Source: dev.to / 3 months ago
After evaluating multiple SDK-as-a-service vendors, including Speakeasy, Fern and Liblab, we selected Speakeasy as our strategic partner. Speakeasyโs philosophy aligns with our mission to deliver an outstanding developer experience. Hereโs why weโre excited about this partnership:. - Source: dev.to / over 1 year ago
SDKs are a powerful way to improve the developer experience of your API. They come with a cost - the amount of work needed to generate them. This is why automation is so important. With liblab you can automate the process of generating SDKs, and keep them in sync with your API as it evolves. - Source: dev.to / almost 2 years ago
When it comes to generating SDKs, liblab is your friend. Liblab is a platform that generates SDKs from your OpenAPI spec, so you can use them in your app. Whether you are accessing internal APIs, or third party APIs, all you need is an API spec, and liblab will generate the SDK for you. - Source: dev.to / almost 2 years ago
At liblab, we tackle complex engineering problems to build SDKs for our customers and their end users, who are engineers themselves. Our team's extensive knowledge in software, software-as-a-service solutions, and developer tools is critical to our success. Therefore, retaining our talented developers is a priority. - Source: dev.to / almost 2 years ago
