urgentry vs Rollbar.

Why this comparison is asking different questions

Most comparison articles put two tools side by side and try to find the winner. This one will not do that, because the tools are not answering the same question.

Rollbar answers: “How do I get production error tracking running today without managing any infrastructure?” The answer is: sign up, grab the SDK, drop in the DSN, done. Rollbar handles the servers, the retention, the alerting infrastructure, and the reliability. You pay a monthly bill and call it solved.

urgentry answers: “How do I run production error tracking on my own hardware, with my existing Sentry SDK investment, at minimal cost?” The answer is: install one binary on a server you control, swap the DSN in your existing Sentry SDK config, done. You manage the server; urgentry handles everything on it.

These are different jobs. The honest answer is that Rollbar is right for teams that do not want to operate infrastructure and are comfortable with a SaaS pricing model. urgentry is right for teams that want their error data on hardware they control, and either already use the Sentry SDK or are starting fresh and want the Sentry-compatible ecosystem.

This article is written by the urgentry team. The bias is what you would expect. The correction is the “when to pick Rollbar” section, which is not a formality.

What Rollbar is

Rollbar is a commercial error tracking SaaS that has been running since around 2012. It is cloud-only: there is no self-host option available for most plans. The product is operated by Rollbar Inc and is not part of a larger observability suite.

The core product covers real-time error tracking across a broad SDK range: Python, Ruby, Node, JavaScript, .NET, Java, PHP, Go, mobile. Rollbar’s SDKs send events to Rollbar’s ingest endpoint using the Rollbar protocol, which is separate from the Sentry envelope format.

Rollbar’s strongest product surface for power users is RQL, a query language that lets you run structured queries against your telemetry data. That is a meaningful differentiator from tools that offer only filtered list views. Deploy tracking is also a first-class feature: Rollbar models deployments explicitly and can show which deploy introduced a given error or resolved a regression.

Pricing is tiered by events per month. There is a free tier, and paid plans start around $99 per month, rising based on event volume and team size. Rollbar’s pricing page covers the current tiers; the numbers change, so treat those as a floor rather than a ceiling.

What urgentry is

urgentry is a self-hosted error tracker that accepts events from Sentry SDKs without any code changes on the client side. The only customer change when switching from Sentry Cloud, Sentry self-hosted, or any other Sentry-compatible server to urgentry is the DSN in each service’s configuration.

The binary is a single Go process. It handles ingest, grouping, storage, alerting, and the web UI in one place. There is no queue to manage, no worker process to monitor, no external services required. SQLite is the default database; Postgres is available for teams that want it. At 400 events per second on reference hardware, urgentry sits at roughly 52 MB of resident memory. It runs on a $5 VPS.

urgentry covers 218 of 218 operations in Sentry’s published OpenAPI schema. It also accepts OTLP/HTTP for traces and logs in the same binary, which means errors, distributed traces, and structured logs all land in one place without a separate observability product.

The license is FSL-1.1-Apache-2.0, the same license Sentry uses for its own source-available distribution. It converts to Apache-2.0 two years after each release. For internal commercial use, the FSL has no practical effect that Apache-2.0 would not also have.

Where Rollbar is ahead

Three areas where Rollbar has a concrete lead that belongs in the comparison.

Managed reliability without operational work

Rollbar handles the servers, the database, the ingest pipeline, the backup strategy, and the uptime guarantee. You do not think about any of that. For a small engineering team where “who monitors the error tracker?” has no good answer, offloading that responsibility to Rollbar is worth the monthly cost. urgentry asks you to run a server. If you will not or cannot do that well, urgentry is the wrong choice.

RQL query language

Rollbar’s RQL lets you write structured queries against your telemetry. Teams that reach the limit of filtered list views and want to ask arbitrary questions about their error data will find RQL useful. urgentry’s current query surface is filtered search and API access; it does not have a query language equivalent to RQL. For power users who depend on that kind of ad-hoc analysis, Rollbar is ahead.

Mature integrations with a 2012 starting point

Rollbar has been in production since around 2012. The integration catalog reflects that: Slack, PagerDuty, GitHub, Jira, and other standard toolchain connections have been built, broken, fixed, and stabilized over many release cycles. urgentry is newer. Its integrations are functional but the breadth and the edge-case depth that comes from years of production use is not there yet. If the specific integrations your team depends on are on Rollbar’s list and you need them to work without configuration surprises, Rollbar has the maturity advantage.

Where urgentry is ahead

Four areas where urgentry has a concrete lead.

Sentry SDK swap with no code changes required

This is the single most important row for any team already on the Sentry SDK. urgentry accepts all 218 documented Sentry API operations. Every SDK your team has shipped continues working against urgentry. The migration from Sentry Cloud, Sentry self-hosted, GlitchTip, or any other Sentry-compatible server is one line per service: the DSN. No SDK code changes, no instrumentation updates, no re-testing SDK behavior.

Rollbar does not accept Sentry SDK payloads. The two SDK ecosystems use different ingest protocols. A team with Sentry SDK instrumentation cannot switch to Rollbar without replacing the SDK on every instrumented service.

Full data on your hardware

urgentry runs on hardware you control. Error events, stack traces, user context, and OTLP telemetry land in a database file on your server and go nowhere else. For teams with GDPR obligations, HIPAA requirements, air-gap deployment constraints, or a general policy of keeping application telemetry off third-party infrastructure, this is not a preference; it is a requirement. Rollbar cannot satisfy that requirement. urgentry is built for it.

$5 VPS footprint

urgentry settles at around 52 MB of resident memory under sustained ingest at 400 events per second. That fits on the smallest commercially available VPS, with memory left for the application it monitors. There are no event volume tiers, no monthly invoices that grow with your traffic, and no conversation with finance about whether a spike in error volume triggered an unexpected bill. The infrastructure cost is the VPS you already run, or a $5 one you add.

OTLP-native traces and logs in the same binary

urgentry accepts OpenTelemetry traces and logs over OTLP/HTTP directly, in the same process that takes error events. If your stack already exports OTLP from Go services, Python services, or Node services, those traces land in the same product as your errors. You get correlation between error events and distributed traces without running a separate observability backend. Rollbar has no OTLP ingest path.

The SDK question

This section decides the comparison for most teams, so it deserves more than a matrix row.

Rollbar and urgentry use different SDK ecosystems. Rollbar errors go through the Rollbar SDK to the Rollbar ingest endpoint. urgentry errors go through the Sentry SDK to the Sentry envelope endpoint. These protocols are not compatible. A service instrumented with the Rollbar Python SDK sends Rollbar-formatted payloads; those payloads do not land correctly in urgentry. A service instrumented with the Sentry Python SDK sends Sentry envelope payloads; those do not land correctly in Rollbar.

What this means in practice: switching from Rollbar to urgentry is a migration project. You replace the Rollbar SDK with the Sentry SDK in every service, update the DSN to point at your urgentry instance, and verify that grouping, breadcrumbs, and release tags come through correctly. That is real engineering work. It is not a disaster for a team that wants to do it, but it is not a config change.

Switching from Sentry to urgentry is a config change. One DSN per service. No code edits.

The honest recommendation: if your team is already on the Rollbar SDK and error tracking is working, the migration cost to urgentry is probably not worth it unless you have a specific data residency or cost driver. If your team is starting fresh, the Sentry SDK ecosystem is larger and has more maintained community SDKs, so that is also a factor in the initial choice. If your team is on the Sentry SDK and is looking at error tracker options, urgentry is a DSN swap and deserves to be on the shortlist.

When to pick Rollbar

• Your team will not or cannot run and maintain a server. Rollbar manages all infrastructure; you log in and look at errors.
• Your compliance posture allows application telemetry in a third-party cloud and you do not have data residency requirements that rule out SaaS.
• Your team already uses the Rollbar SDK across services and the migration cost to a different SDK is not worth the trade-off.
• You need RQL for ad-hoc telemetry queries and the current urgentry query surface is not enough.
• The specific integrations your workflow depends on are in Rollbar’s catalog and you need the stability that comes from years of production use.

If three or more of those apply, urgentry is likely the wrong choice for your team right now.

When to pick urgentry

• You have a data residency requirement, GDPR obligation, HIPAA constraint, or a policy of keeping application telemetry on your own infrastructure.
• You are willing to run one binary on one VPS. The operational overhead is minimal; urgentry is not a complex service to keep alive.
• You already use the Sentry SDK. The migration is one DSN change per service, no code edits, and urgentry covers all 218 Sentry API operations.
• You want errors, distributed traces, and logs in one product. urgentry’s OTLP ingest covers traces and logs in the same binary as errors.
• Your event volume makes SaaS pricing uncomfortable. urgentry has no per-event cost once you are running it on your own hardware.
• You want the option to start on SQLite and move to Postgres later, on your schedule, without a vendor migration conversation.

What this comparison is not

It is not a verdict that Rollbar is a worse product. Rollbar has been serving teams in production since 2012 and its managed reliability, SDK coverage, and RQL query surface are real. Teams that chose Rollbar and are satisfied have no reason to migrate.

It is not a claim that the Sentry SDK is superior to the Rollbar SDK. Both SDK families are maintained, cover the major languages, and do their job. The difference is the ecosystem size and the server-side compatibility surface, not the SDK quality.

It is not a feature checklist where the tool with more checkmarks wins. Rollbar wins more rows on managed features; urgentry wins more rows on data control. Those are trade-offs, not rankings. Different teams have different constraints, and the right tool is the one that fits the actual constraints of the actual team.

The honest frame: these two tools serve teams at different points in their infrastructure philosophy. Rollbar is for teams that want someone else to own the ops layer. urgentry is for teams that want the ops layer to be theirs but kept small. Both are legitimate positions.
