Pricing

$9,600 a year for 16 vCPU. That's it.

Community is free up to 16 vCPU in total. Pro is $9,600 a year including 16 vCPU, then $500 a year for each vCPU beyond that. Nothing is metered by volume, by event, or by host — and HA needs three nodes, which is physics, not a sales floor.

Capacity pricing. $9,600 a year includes 16 vCPU; each vCPU beyond that is $500 a year. Every vCPU allocated to a Sondar server node counts, in every environment, and the free 16 are not subtracted. Nothing is metered by volume, event count, host, agent or user. High availability needs three master-eligible nodes — three 16-vCPU nodes are 48 vCPU, $25,600 a year — because of cluster consensus, not a sales floor.

No SSO tax. Single sign-on with OpenID Connect and SAML 2.0 is in Community. Many self-hosted observability tools, Grafana Enterprise, SigNoz and OpenObserve among them, put SAML sign-in in their paid tier; logging in safely should not cost extra.

Try Pro first. Every new installation runs Pro for its first 30 days, within 16 vCPU — no key and no sign-up. Then it continues as Community: nothing is switched off and no data is touched.

The unit

What counts as a vCPU.

If the unit were "whatever machine you install it on," someone would run one 128-vCPU box and pay for one while a team running three small boxes paid for three. So the unit is one vCPU, and how it is counted is written here rather than left to the license agreement.

Definition

One vCPU = one unit.

Every vCPU allocated to a Sondar server node counts, in every environment. In a container, its CPU limit counts — or the host's vCPUs if none is set. Each hardware thread is one vCPU, and fractions round up. RAM, gigabytes, events, hosts, agents and users aren't counted, and neither are the temporary extra nodes of an upgrade or a reschedule.

What it works out to

Plan on about 500 GB/day per 16 vCPU with 16 people searching at once — measured at the default heap, with a replica and on syslog and JSON logs, about 730-800 GB/day held — so Pro works out at about 5 cents per GB ingested. 64 vCPU at about 2 TB/day is $33,600, a little under 5 cents. Ingest alone measured about 2.6 TB/day per 16 vCPU; the sizing page has the measurements and the hardware. The model neither rewards nor punishes how densely you pack, which is the property you want from a capacity license.

This is capacity licensing, not consumption metering, and the difference is the whole argument. We attack per-gigabyte pricing because it makes every decision about visibility a decision about money. Charging for the compute you chose to provision doesn't do that — nobody has ever hesitated to turn on debug logging because of a vCPU count. Per-core licensing is also how Oracle, VMware, SQL Server and Confluent have always worked, so it carries no explanatory burden.

Why does this default to 12 months? Because per-gigabyte vendors charge again for time, and we think you should keep a year. Drag it down to 30 days and we land at rough parity with Grafana Cloud — that's the honest picture, and it's exactly why the argument here is retention rather than ingest.

Assumptions, rates, and what this deliberately understates
Sondar license Pro, at $9,600 a year including 16 vCPU, then $500 per additional vCPU. Plan on about 500 GB/day per 16 vCPU / 32 GB box with 16 people searching at once (measured at the default heap, with a replica and on syslog and JSON logs; ingest alone ran about 2.6 TB/day), so the model sizes ceil(GB per day ÷ 500) such boxes. Priced as Pro even where Community's free 16 vCPU would cover it, because the rivals here are paid production plans. Published price, October 2026.
Your hardware $4,500 per node per year — the midpoint of a $2,000–$7,000 range covering a 16-core server amortized or its cloud-instance equivalent. This is an estimate, and it is the one number in this table that is ours rather than a vendor's.
Your object storage $0.023 per GB-month (S3 Standard, us-east-1, July 2026) applied to the retained volume after the measured 3.0x compression of raw logs. Cheaper on infrequent-access tiers, which we don't assume.
Grafana Cloud ~$0.50 per GB ingested, 30-day retention included. July 2026.
Datadog Logs $0.10 per GB ingested plus $1.70 per million events indexed at 15-day retention on an annual commitment, July 2026. Event count is derived at 1 KB per event, which is the single biggest lever in this row — the indexing line scales with event count rather than volume, so if your logs average 500 bytes, double this figure. On-demand indexing is $2.55 per million rather than $1.70.
Splunk Cloud ~$1,000 per GB/day per year on ingest-based pricing, July 2026. Workload pricing (SVCs) can be materially cheaper at scale and is not modelled.

What this understates. The three competitor bars are ingest only, at their included retention window — they do not charge you for the retention you selected above, even though all three do in reality. We model it that way because we won't publish a guess at a rate we can't cite. So the comparison is more favorable to them than their real invoice would be. Sondar's bar, by contrast, is the whole cost: license, hardware, and storage for the full retention window.

What it leaves out on both sides. Operator time. Running Sondar is one container, but it isn't zero — and neither is the alternative of continuing to run what you have.

What's in each edition

The gates, in full.

Community is gated on capacity — 16 vCPU in total, one master-eligible node — and never on data. Pro adds what running it for other people needs: high availability, cold storage, finer access control and committed support. Nothing is listed until the code does it.

Pricing questions.

Q1 Is Sondar open source?

No. Sondar is commercial software and we don't publish the engine's source — we'd rather say that plainly than blur it. What we publish today: an SBOM with every release, a signed release manifest, and a written cap on renewal pricing. We don't offer source escrow, and a source code audit or penetration test is not a standing commitment — we'd rather say that than date one. What does stand: any index can be archived to your own object storage as gzipped JSON, so nothing you've collected has to depend on us.

Q2 How is this different from SigNoz, OpenObserve, or Grafana?

They're good, and if you're happy with them you should stay. The difference is the analytics layer and the operating burden. SigNoz means you now run and scale ClickHouse and Kafka; Grafana's LGTM stack is four systems to operate. Sondar is one engine with one store for logs, metrics and traces, and a Splunk-class query language — stats, join, transaction, timechart — rather than a filter syntax. On raw storage efficiency, OpenObserve and VictoriaLogs publish bigger numbers than ours. We're not claiming to beat them there.

Q3 Is SonQL the same as Splunk’s SPL?

No. SonQL is Splunk-inspired, not Splunk-compatible — your existing Splunk searches will not run unmodified, and we're telling you that here rather than letting you find out on day one. What does transfer is everything you know about how to search machine data. Most Splunk users are productive in SonQL in an afternoon. There's a command-by-command translation table in the docs and a converter you can paste a query into.

Q4 What are the actual hardware requirements?

Plan on about 500 GB/day for one server with 16 vCPU and 32 GB of RAM, with 16 people searching at once. Retention is bounded by your disk and your object storage, not by us. Above that, Sondar clusters. That figure keeps headroom for peaks: on such a server, ingest alone measured about 2.6 TB/day, and about 730 GB/day of syslog lines and 800 GB/day of JSON logs held steady while 16 searches ran at once -- at the default 4 GB heap, with 20 alert rules running and with a replica, three or more runs each. The measurements, with their hardware, are on the docs' sizing page.

Q5 What counts toward my license?

vCPU, and nothing else. Every vCPU allocated to a Sondar server node counts, in every environment — in a container, its CPU limit, or the host's vCPUs if none is set. We don't count RAM, gigabytes, events, hosts, agents or users. Community is free up to 16 vCPU in total; Pro is $9,600 a year including 16 vCPU, then $500 a year for each vCPU beyond that. The price is the same whether you run four small boxes or one large one, so the model neither rewards nor punishes how you pack them.

Q6 Can I try Pro before buying?

Yes, without asking us. Every new installation runs Pro for its first 30 days, within 16 vCPU — no key, no sign-up, and the product sends nothing to us. The clock starts at the first start and a restart does not reset it. When it ends the installation simply continues as Community: nothing is switched off and no data is touched, and any Pro configuration you made — custom roles, masking rules, cold storage tiers, SCIM — keeps running and can be reduced or removed, just not created or expanded until you add a Pro key.

Q7 Will my bill go up as we grow?

Yes, with capacity — if you add vCPU you license them. What won't happen is a bill that moves because you ingested more, kept data longer, added tags, or stopped sampling. Nothing you do inside the product generates a line item.

Q8 Can I run this air-gapped?

Yes, genuinely. Licenses are signed keys your instance verifies offline against a public key baked into the binary — there is no activation server to reach, so Sondar never calls home. An update is the new image, carried in the way the first one was and started on the same data volume, on every tier including Community — patching a disconnected install is not a paid feature.

Q9 What happens to my data if Sondar goes away?

It's already on your infrastructure — we never had it. Anything you archive to your own object storage is gzipped JSON you can read without us, and your instrumentation is OpenTelemetry so it repoints anywhere. We don't offer source escrow; open formats in your own storage are the answer we can stand behind.

Q10 What happens if my single node dies? There’s no HA on one node.

Correct, and worth being explicit about since Community runs one master-eligible node. What sits on the node is the hot window, the configuration and the metadata. Data you tier or archive to your own object storage survives the node, and an archive is gzipped JSON you can read without us. What we do not do yet is snapshot the hot window and the metadata continuously, so we publish no recovery-point or recovery-time figure rather than one we have not measured. If losing the hot window is not acceptable, run three nodes — that is genuine HA, and it is physics, not a sales floor.

Q11 Do you support SSO?

Yes, in Community: OpenID Connect and SAML 2.0 single sign-on, alongside LDAP and CAS. We don't charge to log in safely. Pro adds SCIM provisioning, so your identity provider creates, deactivates and deletes Sondar accounts; if Pro ever lapses, it can still deactivate and delete, just not add. We have tested sign-in end to end against Keycloak and SCIM with the requests Okta and Entra ID send. An audit log is not offered yet.

Q12 Do you have SOC 2? HIPAA?

No, and we have not scheduled one. SOC 2 audits how a vendor handles your data, and we never receive your data: Sondar runs on your machines and sends nothing to us. For the same reason we're generally not a HIPAA Business Associate and no BAA is required — the PHI never leaves your environment. What we have today: an SBOM with every release, a signed release manifest the server checks at boot, a published vulnerability disclosure address with a response SLA, and a completed security questionnaire on request. We'll revisit SOC 2 if we run a hosted service or a customer needs it.

Q13 How long is a release supported?

Each minor release is supported for 12 months from its release, and fixes, including security fixes, are provided in the latest minor release — you take them by upgrading. Upgrades are an image swap on the same volume: schema migrations run at boot, and the built-in apps update their code without touching your edits. Copy the volume first and rolling back is restoring that copy. The upgrade guide in the handbook has every step. Versioned releases haven't started yet; until the first one, there is one line and every image moves forward.

Q14 Who builds this, and where are you based?

Sondar is built in Mountain View, California. The whole team is in the Bay Area — founder, engineering and support — and I answer the tickets myself. The more useful half of that answer is what it means for your risk: Sondar runs entirely inside your network and we never receive your data, so there is no vendor to breach that holds your telemetry. For the binary itself we publish an SBOM with every release and sign a manifest of every file we ship, and the product sends nothing to us, so a firewall rule can prove it. We're small and new, and we'd rather hand you things you can check than ask you to take our word for it.
