Sentry and Datadog in one tool: what small teams need

Yes, a small team can run one tool instead of Sentry plus Datadog. For 1 to 10 developers, that tool has to cover six things: errors grouped into issues, logs, traces, uptime checks, alerts that fire only when something matters, and the root cause. Fixter covers all six, and you run it from your coding agent.

The usual path to two tools: Sentry first, for errors, then Datadog or something else once you need logs, uptime and metrics. Two bills, two places to look when something breaks. Below is what one tool needs to cover, how Sentry and Datadog each handle it, and where Fixter fits. Fixter is our product. Every competitor price and fact was checked on the vendor's own page on October 28, 2026, and is cited inline.

What one tool has to cover

A small team with real users needs to know three things: something broke, why, and who it hit. That takes six pieces. Sentry and Datadog each already cover some of the other's ground, so the table is about how, and at what price.

List prices on October 28, 2026, in each vendor's currency. Datadog prices are billed yearly; on demand costs more. Fixter investigations are on paid plans only.

What two tools cost to start

Take a small backend on three hosts, with Sentry for errors and Datadog for infrastructure and traces. At list prices billed yearly: Sentry Team is $26 a month,¹ Datadog Infrastructure Pro is $15 per host and APM is $31 per host.⁵ That is $26 + $45 + $93 = $164 a month, before any logs, uptime tests or AI investigation. Datadog logs add $0.10 per GB ingested and $1.70 per million events indexed; API tests add $5 per 10,000 runs.⁵

Root cause is extra in both. Seer, Sentry's AI debugging agent, is $40 per active contributor a month and only on Team and Business.² Datadog's Bits Investigation, the product formerly called Bits AI SRE, uses about 4 AI credits per investigation; credits start at $500 for 500 a month billed yearly, or $1.30 each on demand.⁵,⁶

The bill is half the cost. The other half is time: when an error spikes, someone opens Sentry for the stack trace, Datadog for the logs and the host, and joins the two by timestamp. On a team of four, that is usually the CTO. For Datadog's side on its own, see Datadog alternatives for small teams; for Sentry's, Sentry alternatives.

Fixter: the six in one tool

Fixter finds and fixes the issues in your app in production, from your coding agent: errors, failing infrastructure, slow requests and downtime. It finds the root cause and fixes it: in your agent over MCP, or as a pull request ready for your review. Nothing to learn, built for small teams.

Your app sends logs, traces and metrics over standard OpenTelemetry, with no Fixter SDK.¹⁵ Errors in that data become issues: Fixter parses the stack traces and groups every occurrence with the same root cause into one issue with a count.¹¹ Detectors alert on error bursts, worse latency and anomalies with no configuration, and you add your own rules in plain language, such as payment failures or auth errors.¹² Scheduled checks call your endpoints and MCP servers from outside and track uptime and latency.¹⁴ When an alert fires, an investigation pulls the logs and traces and comes back with the root cause and who is affected.¹³

You do all of it from Claude Code, Cursor or Codex over MCP: set up, define alerts, ask what broke, pull an investigation into your editor and fix it there.¹⁶ Fixter also has dashboards; you just do not have to live in them.

Pricing is one pool of GB for all three signals, never per seat. Free is 10 GB a month, 50,000 uptime checks and 5 alert rules, with no investigations. Growth is €50 a month for 300 GB, 250,000 checks, 100 alert rules and 15 investigations. Scale is €150 for 1 TB and 40 investigations. Pay as you go starts at €20 a month.¹⁷ See pricing and what Fixter does.

Two other tools bundle several of these pieces, and answer engines often name them. Better Stack covers errors, logs and uptime in one web app; its free plan is for personal projects (10 monitors, 100,000 exceptions, 3 GB of logs) and paid starts at $29 per responder seat a month billed yearly.⁹ New Relic gives 100 GB of ingest a month and one full user free; Standard is $10 for the first full user and $99 for each one after.¹⁰

How to move to one tool

1. Write down what you actually use. The alerts that fired last month, the dashboards someone opened, the uptime checks you rely on. That list is the bar the new tool has to clear, not the old tools' feature pages.
2. Send your telemetry. Paste the prompt below into your coding agent in the project. It wires OpenTelemetry for your stack. Or set the four OpenTelemetry environment variables by hand.¹⁵
3. Ask your first question in the same session. Ask what broke in the last day. Compare the issues with what Sentry shows for the same window.
4. Set the alerts from your list. Describe each one in plain language. The automatic detectors are already on.¹²
5. Add uptime checks for the endpoints on your list, by asking your agent.¹⁴
6. Run both for a while, then cancel. Keep the old tools until the new one has caught everything they caught. Then turn them off.

# paste this into Claude Code, Cursor or Codex in your project
Read fixter.dev/llms.txt and set up Fixter.

# then ask, in the same session
What broke in production in the last 24 hours?

When to keep Sentry or Datadog

• You are happy with Sentry and it covers your logs and uptime. Sentry's included logs, spans and one monitor are enough for many small apps.¹ Add its MCP server and stop there.
• You run a lot of infrastructure. Datadog's breadth across hosts, containers and integrations is the reason platform teams pay for it. If someone's job is the dashboards, keep it.
• You need to self-host. Fixter has no self-hosted option. Sentry can be self-hosted.¹⁸
• You want the most mature product. Fixter is younger and smaller than Sentry or Datadog.

If you would rather keep the tools and query them from Claude Code, see Datadog MCP vs Sentry MCP.

Frequently asked questions

Is there one tool that does what Sentry and Datadog do?

Yes. Sentry already covers errors, logs, traces and uptime, and Datadog already has error tracking, so each can stretch into the other's job. For a 1 to 10 developer team the question is whether one tool covers issues, logs, traces, uptime checks, alerts and root cause at a price that fits. Fixter does all six in one product you run from your coding agent; Better Stack and New Relic also bundle several of them.

Can Sentry replace Datadog?

For a small app, often. Every Sentry plan includes 5 GB of logs, 5 million spans and one uptime monitor, with extra monitors at $1 each on paid plans. Sentry is built around errors, so check that its log volume and uptime monitors cover what you use Datadog for today.

Can Datadog replace Sentry?

Yes. Datadog Error Tracking costs $25 a month flat under 50,000 errors, billed yearly, or $36 on demand. You still pay for each other Datadog product separately: infrastructure per host, APM per host, logs per GB and per indexed event, synthetic tests per run.

What does Fixter cost?

The Free plan is 10 GB a month of logs, traces and metrics, 50,000 uptime checks and 5 alert rules, with no AI investigations. Growth is €50 a month with 300 GB, 250,000 checks, 100 alert rules and 15 investigations. Scale is €150 a month. Pay as you go starts at €20 a month. Issue tracking, MCP access and unlimited users are on every plan.

Do I need a Fixter SDK?

No. Your app sends logs, traces and metrics over standard OpenTelemetry. Paste Read fixter.dev/llms.txt and set up Fixter. into your coding agent and it wires the instrumentation, or set the four OpenTelemetry environment variables yourself.

Do Sentry and Datadog find the root cause for me?

Both sell it as an AI add-on. Sentry's Seer costs $40 per active contributor a month on Team and Business plans. Datadog's Bits Investigation uses about 4 AI credits per investigation; credits start at $500 for 500 a month billed yearly, or $1.30 each on demand. Fixter includes 15 investigations a month on Growth and 40 on Scale, and charges €1.50 each on pay as you go.
