Datadog alternative: Vigil
Teams look for a Datadog alternative when the bill for three hosts, a few synthetic checks and some logs crosses a few hundred dollars a month and nobody can explain why. Vigil replaces the parts a small team uses (host metrics, logs, uptime, Kubernetes, RUM) at $10/month. If you rely on distributed tracing across a dozen services or profiling, Vigil is not a replacement.

Small-team estimate uses public list prices and the cheapest tier that covers 3 servers, 50 monitors at 1-minute intervals and 5 people. Where a vendor meters by run, GB or hour we show the arithmetic so you can redo it with your own numbers.
What Datadog does well
- Unmatched depth: 800+ integrations, distributed tracing in every major language, profiling, security, cloud cost, and dashboards that can do anything.
- Everything correlates: a trace links to its logs, host metrics and the deployment that caused it.
- Enterprise-grade access control, compliance and support.
Where Vigil is ahead
- Every product is a separate SKU with its own meter: hosts, GB, events, runs, sessions. Bills are hard to predict and famously grow.
- Synthetic checks are billed per run; a 1-minute uptime check is 43,000 runs a month before you add locations.
- No status pages for your customers.
- Serious operational overhead for a 3-person team; you need someone to own the Datadog setup.
When to pick Datadog instead
Pick Datadog if you run many services and need distributed tracing and profiling, if you have a platform team that will maintain dashboards and integrations, if you need compliance certifications and enterprise support, or if browser-level synthetic tests are essential.
What Vigil does not do
- No browser / Playwright checks: Vigil scripts APIs, not clicks in a real browser.
- No SMS or phone-call alerting; alerts go to chat apps, push services, email, webhooks and ticketing tools.
- No on-call rotations or schedules: escalation policies and acknowledgements only.
- APM covers Python and Node apps on hosts running the agent; it is not a substitute for a full APM suite.
- Checks run from Vigil's servers plus private locations you host; there is no menu of dozens of public regions.
Moving from Datadog to Vigil
1. Export what you have
List your Datadog monitors (their API or UI export). You need a name, URL or host, interval and the expected status or keyword for each.
2. Apply as code
Write them as Vigil's YAML and apply with PUT /api/v1/config; the same endpoint exports everything back, so monitors can live in git. Or create them one by one through the REST API (monitors, incidents, maintenance, deploy markers).
3. Reconnect alerts
Add Telegram, Slack, Discord, Teams, ntfy, Pushover, email or webhook channels; set escalation to a second channel set. Point your cron jobs at the new heartbeat URLs and install the server agent with one command.
Run both side by side during the trial: Vigil's alert ingestion accepts Alertmanager and Grafana-style webhooks, so existing alerts can appear on a Vigil status page while you move over.
Frequently asked
Can Vigil replace Datadog?
For a small team running a handful of servers, a Kubernetes cluster and some web apps: usually yes, for host metrics, logs, uptime, heartbeats, Kubernetes health, Web Vitals and alerting. For distributed tracing across many services, profiling or hundreds of integrations: no.
How does Vigil's APM compare?
Vigil's agent collects endpoint latency, error rates, request traces and a service map from Python and Node apps on the same host. That is enough to see which endpoint is slow and which downstream call caused it. It is not Datadog APM.
How much would a 3-server team pay on each?
Vigil Pro: $10/month, everything included. Datadog: $45/month for infrastructure at the Pro tier, plus APM at $31 per host, plus logs by volume, plus synthetic runs, each on its own meter. Actual Datadog bills for small teams commonly land in the hundreds.
Can I keep Datadog for tracing and use Vigil for uptime and status pages?
Yes. Vigil can also open tickets in Datadog from its incidents, and its alert ingestion endpoint accepts Alertmanager and Grafana-style webhooks, so you can route Datadog monitors to a Vigil status page.
