What does error tracking cost at 50k, 250k and 1M events a month?
At 50,000 errors a month the entry plans cost $20 to $29. At about 250,000 they cost $65 to $79, and at 1 million $176 to $225, depending on vendor and billing. Price alone separates them less than retention, what happens when you go over, and whether your coding agent can read and resolve the errors. Runheed is flat: $29, $79 and $199 a month, and events over the limit are rejected, never billed.
The prices at three volumes
Each figure comes from the vendor's own pricing page on November 11, 2026, for the cheapest paid plan that covers the volume. Where a vendor sells in steps, the price is for the first step at or above the volume, shown in brackets.
| Tool and plan | 50k errors/month | About 250k | 1M | Retention |
|---|---|---|---|---|
| Runheed (flat, monthly) | $29 (Solo) | $79 (Pro, 250k) | $199 (Scale) | 30 / 90 / 180 days |
| Sentry Team (billed annually, reserved volume) | $26 | about $67 | about $186 | Up to 90 days |
| Sentry Team (billed annually, pay-as-you-go over 50k) | $26 | about $77 | about $225 | Up to 90 days |
| Honeybadger Team (monthly) | $26 | $74 (300K) | $176 | 90 days |
| Rollbar Essentials (monthly) | $29 | $79 (300k) | $199 | 90 days |
| BugSnag Select (list price) | $20 | $65 (300k) | $200 | 60 days |
Sentry's figures add its published per-error rates for the Team plan to the $26 base, which includes 50k errors: reserved volume is prepaid at a discount, pay-as-you-go is billed after the fact. Sentry rounds those rates, so treat the totals as close, not exact. Honeybadger's figures are its Team base plus the error add-on from its pricing calculator. Rollbar and BugSnag publish a price for each step.
What the price does not show
- Going over: Sentry bills extra volume from a pay-as-you-go budget you set; the stepped plans move you up a step. Runheed rejects events past the plan limit and tells you, so the bill never changes.
- AI fixing: Sentry sells its AI debugging agent, Seer, on top of the plan ($40 per active contributor a month until December 8, 2026, then usage-based credits). With Runheed your own coding agent does the fix over MCP, with no add-on.
- Agent access: all five offer an MCP server, so the question is what the agent can do with it. The comparison of error tracking MCP servers covers that tool by tool.
- Everything else: Sentry, Honeybadger and BugSnag bundle tracing, uptime, logs or mobile stability. Runheed does errors only, with Node.js and Python SDKs and no browser or mobile SDK yet.
How to pick on cost
- Count your real error volume for a month (most trackers show it on the usage page). Expect spikes after a bad deploy.
- Price the step above your volume, not the one at it: a spike to the next step is where the bills differ.
- Decide what you want to happen at the limit: pay for the extra, or drop it.
- Add what you would pay for AI fixing, if you want it, on top of the plan.
Questions
- Which error tracker is cheapest?
- At these three volumes, BugSnag Select is lowest at 50k and about 250k, and Honeybadger Team is lowest at 1M. The gaps are small, a few dollars to a few tens of dollars a month, so retention and overage rules usually matter more.
- Does Runheed charge for overage?
- No. Each plan has a monthly event limit (50,000, 250,000 or 1,000,000). Events past it are rejected, not billed, and you can move to a bigger plan any time.
- Are these prices current?
- They were read from each vendor's pricing page on November 11, 2026. Vendors change prices; check their pages before you buy. Sentry's Seer pricing changes on December 8, 2026.
