Terraform Run Log Analyzer

The Terraform Run Log Analyzer takes the raw stdout and stderr of a terraform plan, apply, or destroy run and turns it into a concise, scannable summary of errors and warnings. Terraform run output is verbose, interleaving progress lines, drift notes, and resource changes with the problems you actually care about. When a plan fails or a CI pipeline goes red, engineers waste time scrolling through hundreds of lines hunting for the failure. This analyzer scans the text locally, classifies each line as an error, a warning, or noise, and presents a short report with counts and the matching lines grouped together. It recognizes common failure markers such as error:, failed, and panic, and it treats warning: lines as warnings. Everything runs in your browser, so the logs you paste are never uploaded and no Terraform Cloud connection is made. Use it to triage a failing run quickly, to attach a clean summary to a bug report, or to teach teammates how to read Terraform output. The report is plain Markdown, so it drops straight into a pull request comment or a chat message. It is especially useful in CI environments where only the truncated tail of a log is visible, because pasting the full output here recovers the complete failure context. Because the detection rules are simple and transparent, you can trust that nothing is hidden or rewritten, and the original lines are preserved verbatim in the report. The analyzer is a calm, fast alternative to grepping a terminal when a teammate shares a failure and you want the headline numbers immediately.

• Error detection - flags lines containing error:, failed, and panic as errors.
• Warning detection - captures lines containing warning: as warnings.
• Grouped report - errors and warnings are listed in separate, clearly headed sections for quick scanning.
• Counts - quick error and warning totals appear at the top of the report.
• Stats row - the UI shows error and warning totals beside the preview.
• Markdown output - the report is ready to paste into pull requests or chat without editing.
• Clean handling - noisy progress lines are ignored so signal stands out.
• Multi phase - works for plan, apply, and destroy runs alike.
• Private - nothing is uploaded and no cloud connection is made, so secret free logs stay secret.
• Copy, download, print - export the report as a .md file for any workflow.
• Clipboard safe - plain text is copied without markup.
• Fast - instant triage entirely in the browser.

1. Paste the run log or terminal output into the text area on the left.
2. Click Analyze log to scan the pasted text for problems.
3. Read the error and warning counts shown in the stats row above the preview.
4. Review the grouped Error and Warning sections to see the exact offending lines, so you can copy just the relevant ones.
5. Copy the Markdown report with a single click for sharing.
6. Download it as a .md file or print it for your records and tickets.
7. Attach the summary to a bug report or pull request comment.
8. Re-run terraform after fixing the reported issues and analyze again.

Example 1 - a log containing "Error: failed to create S3 bucket: AccessDenied" and "Warning: deprecated attribute acl" yields one error and one warning in the report, each shown with its full line. Example 2 - a clean apply with "Apply complete! Resources: 2 added." produces a report stating No errors detected and No warnings detected. Example 3 - a panic line is captured as an error so crashes are never missed by the summary. Example 4 - a log mixing progress lines with two errors still reports exactly two errors and ignores the surrounding noise, keeping the signal clear.

• Fast triage - see problems at a glance instead of scrolling.
• Shareable - export a clean, readable summary for others.
• Local - no uploads and no cloud API calls are made.
• Accurate - reliably catches errors and warnings in run output.
• Teaching - helps newcomers learn to read Terraform output.
• Portable - the Markdown report works anywhere text is accepted.
• Transparent - detection rules are simple and nothing is rewritten or hidden.
• Calm - turn a wall of text into a short, readable summary you can act on.
