Top Features to Look for in a Proxy Service
What are the top features to look for in a proxy service? From pool depth to session control to API access, these are the features that determine real-world value.
Evaluating proxy services is easier when you know which features actually affect your operation versus which are marketing-driven additions that look good on a spec sheet. This guide covers the features worth prioritizing and explains why each one matters in practice.
Pool Size and Active IP Count
The headline "X million IPs" number is common in proxy marketing, but raw IP count is less meaningful than active IP count and pool diversity. A pool with 100 million registered IPs but only 20 million active at any time behaves like a 20-million IP pool.
What matters more than headline count:
- Active IP availability at the concurrency your jobs require
- ASN diversity — IPs spread across many autonomous systems, not clustered in a few
- Geographic distribution that matches your targeting needs
Ask providers whether the stated pool size reflects total registered IPs or currently active IPs. The difference is significant for high-concurrency operations.
Geographic Coverage and Targeting Precision
Country-level coverage is table stakes. The features worth evaluating more carefully:
City-level targeting: Essential for ad verification, local SEO, and regional market research. Providers vary significantly in how many cities they can target accurately and what the geo-accuracy actually is.
Country and city coverage verification: Before committing, test geo-accuracy in your specific target markets. Request IPs in 5–10 of your most important cities and verify where they geolocate.
Carrier or ISP targeting: Some workflows require not just a country or city but a specific ISP or mobile carrier. This level of targeting granularity is not universally available.
Session Control Options
Session configuration determines which workflows the proxy can support.
Rotating sessions: IP changes automatically on each request or on a configurable schedule. Essential for stateless, high-volume collection.
Sticky sessions: IP remains fixed for a configurable duration. Essential for multi-step, stateful workflows. Look for maximum session duration options that cover your longest workflows.
Session ID control: The ability to specify session identifiers programmatically so your orchestration layer can manage multiple concurrent sessions with different IPs without relying on automatic assignment.
Proxy Types Offered
Providers that offer multiple proxy types allow you to match each workload to the appropriate infrastructure.
Rotating residential: The baseline for most scraping and research use cases. Dedicated ISP: For persistent, stable sessions with residential-classified IPs. Datacenter: For cost-sensitive, high-throughput workloads on permissive targets.
A provider that offers only one type forces you to either over-pay (using residential for all workloads including those that do not need it) or use multiple providers with the operational overhead that implies.
API and Integration Quality
Programmatic proxy management is essential for production operations. Evaluate:
API for targeting parameters: Can you set country, city, session ID, and rotation behavior programmatically, or only through a dashboard?
Authentication options: Username/password and IP allowlisting. Both should be available.
Tool compatibility: Does the gateway endpoint work out of the box with your scraping framework, browser automation tool, or HTTP client?
Usage reporting API: Can you query your usage data programmatically so your internal tooling can monitor bandwidth consumption and costs?
Uptime and Reliability Guarantees
For production workloads, gateway availability directly affects collection continuity.
SLA commitments: Does the provider offer a stated uptime percentage with remedies for underperformance?
Status page: Is there a public status page showing historical uptime and current incidents?
Redundancy: Does the provider have multiple gateway regions or failover infrastructure?
Support Quality
As covered elsewhere, proxy support quality is a critical operational factor. Features worth verifying:
- Live chat availability and average response time
- Technical depth of the support team
- Documentation completeness for your use cases
- Escalation path for urgent production issues
FlameProxies provides residential and datacenter proxy access with city-level geographic targeting, rotating and sticky session support, API access for programmatic configuration, and support through live chat and email. Evaluating these features during a trial against your specific targets and workflows is the most reliable way to confirm they perform as described.
