DNSFilter is built for DNS-layer threat filtering, MSP multi-tenancy and roaming device protection. The reasons to look elsewhere are less about a missing feature than the buying experience: Reddit users report query-based billing surprises, false positives that create helpdesk calls, and concerns about AI in support. NextDNS is the closest listed fit for configurable DNS filtering. The other options here serve narrower or broader needs, so check that they replace the job DNSFilter does for your team before you switch.
01Why people leave DNSFilter
Query-based billing surprises
One Reddit user says bulk-discount billing is based on query volume, not agent count, and that usage reviews can feel unpredictable to accounting.
Support trust concerns
One APAC MSP thread alleges an AI support agent presented itself as a person. Commenters said that raised concerns about trusting the vendor.
False positives add workload
A Reddit user reports DNS filtering can cause false positives and helpdesk calls, while noting that this is not unique to DNSFilter.
02The alternatives, ranked by fit
- Configurable DNS filtering
NextDNSNextDNSNextDNS is the closest listed alternative if your main reason for leaving is the DNS-filtering experience, rather than a need for a broader security platform. Its listing highlights configurable DNS controls and ad and tracker blocking. The listed price starts at $2.325 and includes a free plan; the published information does not say what that price covers.
Trade-off: The listing warns of occasional breakage and community-level personal support.

CA$2.33/mofree plan - School filtering
LinewizeLinewizeLinewize is a better fit if your DNSFilter use is tied to school safety or classroom controls. Its listing positions it for districts and schools, not as a general MSP replacement. It also flags support as a strength, but pricing is not published on the vendor's site, so get a quote and verify coverage before moving users.
Trade-off: Verify Windows and VPN coverage; pricing is not published.
7.4/10from
Custom - DDI management
BlueCat EdgeBlueCat EdgeBlueCat Edge is worth considering when the underlying need is managing DDI across cloud and on-premises environments, connecting remote branches, or automating DDI through APIs. That is a different buying case from replacing DNSFilter’s filtering. The listing gives no starting price, and says public pricing and limits make value hard to assess.
Trade-off: It is a DDI platform, not a direct DNS-filtering replacement.
5.8/10from
Custom - Broader security platform
Zscaler Cloud IPSZscaler Cloud IPSConsider Zscaler Cloud IPS if your organization is already considering Zscaler or wants a broader security platform rather than a like-for-like DNSFilter swap. The pricing page recommends getting the Cloud IPS scope and a quote in writing first. Pricing is not published, so compare the quoted scope with the filtering work you are replacing.
Trade-off: Quote-only pricing and Cloud IPS scope need clarification.
5.5/10from
Custom - Zero trust controls
Zscaler Zero Trust ExchangeZscaler Zero Trust ExchangeZscaler Zero Trust Exchange fits teams consolidating zero trust controls, securing private app access, or protecting AI deployments. Those are broader goals than DNS filtering, so treat this as a platform change, not a direct substitute. The listing notes meaningful access limits and no published pricing; confirm both against your intended deployment.
Trade-off: No published pricing; the listing flags access limits.
6.3/10from
Custom - Firewall and VPN
pfSense PluspfSense PluspfSense Plus may fit if the switch is part of a move toward network firewall, VPN or VPC connectivity, rather than a standalone DNS-filtering replacement. Its listing names Netgate appliances and AWS or Azure deployments as target use cases. The listed price starts at $10.75 and includes a free plan; check the full bill and upgrade terms.
Trade-off: It is a network-functions option, not a direct filtering substitute.
6.7/10from
$10.75/mofree plan - Business firmware
OPNsense Business EditionOPNsense Business EditionOPNsense Business Edition suits teams that specifically want a commercial firmware repository, are considering OPNcentral for multiple installations, or need included security features. That makes it a different route from buying DNS-layer filtering. The listed starting price is $11.08; weigh that upfront cost against the business features you actually need.
Trade-off: The listed price is upfront; fit depends on your firmware needs.
