Key difference

The agent gap

Surfe is a Chrome extension. It requires a human sitting in front of LinkedIn in a browser. There is no CLI, no MCP server, and the API is gated with undisclosed pricing. AI coding agents cannot interact with Surfe at all.

Deepline is a CLI. An agent calls deepline enrich the same way it calls git or curl. Structured inputs, structured outputs, no browser required.

bash
# An agent can do this in Claude Code:
deepline enrich leads.csv --waterfall --providers hunter,prospeo,icypeas
deepline enrich company.csv --providers crustdata,pdl --fields firmographics

# Surfe has no CLI, no MCP server, no agent interface

Pricing

Per-seat fees add up fast

Surfe charges per user, per month. A 5-person team on Pro pays $295/mo (annual) or $395/mo (monthly), and each user gets only 1,000 email credits per year. Credits that go unused in a month do not roll over. As of March 2026, verify pricing on surfe.com.

Deepline has no per-seat fees. BYOK mode is free. Managed credits run $0.08–$0.10 per credit. No platform fee, no minimum spend, no annual contract. A 5-person team pays exactly the same as a 50-person team: nothing for the platform, and only for the lookups they actually run.

Common questions

FAQ

Is Deepline really free?

With BYOK (Bring Your Own Key), Deepline is free. You pay providers directly. Or buy Deepline credits (from $0.08/cr at Scale) and we handle billing. No platform fee, no per-seat charge, no minimum spend.

How much does Surfe cost?

As of March 2026, Surfe charges $29-79/user/month (annual billing). The Essential plan ($29/user/mo) includes 150 email credits per year and 50 phone credits per year. The Pro plan ($59/user/mo) includes 1,000 email and 100 phone credits per year. Monthly billing is higher ($39 and $79 respectively). Credits refresh monthly with no rollover. Verify current pricing on their site.

Can AI agents use Surfe?

No. Surfe is a Chrome extension that requires an active LinkedIn browser session. There is no public CLI, and their API is gated with undisclosed pricing. AI coding agents like Claude Code, Codex, or Cursor cannot drive Surfe programmatically. Deepline is CLI-native, so agents call it the same way they call git or curl.

Does Surfe support bring-your-own API keys?

Partially. Surfe lets you connect keys for 12 providers (including Dropcontact, Hunter, Apollo, and ZoomInfo), but you still pay Surfe's per-seat fees on top. With Deepline, BYOK is the default with zero platform markup. You connect your own keys and pay providers directly.

What does Surfe do better than Deepline?

Surfe genuinely excels at LinkedIn-to-CRM workflows. The Chrome extension overlays directly on LinkedIn profiles, letting sales reps sync contacts to Salesforce, HubSpot, or Pipedrive with one click. It also logs LinkedIn messages to your CRM automatically. For individual SDRs who live in LinkedIn and want turnkey CRM sync without touching a terminal, Surfe is a strong choice. It has a 4.6/5 rating on G2 with 433+ reviews (source: g2.com/products/surfe/reviews), and email validation is unlimited on all plans.

How do credit limits compare?

Surfe's Pro plan includes 1,000 email credits and 100 phone credits per year per user, with monthly refresh and no rollover. A 5-person team on Pro gets 5,000 email lookups per year total. Deepline has no credit limits. With BYOK, you pay providers per lookup with no cap. With managed credits, you buy what you need.

Can I use Deepline if I'm not technical?

Deepline requires a terminal today. If your team browses LinkedIn and needs one-click CRM sync without any CLI interaction, Surfe is likely a better fit. If you have a GTM engineer or use AI coding agents like Claude Code, Deepline integrates naturally into developer workflows with far more enrichment depth.
