## Articles

- [Monorepo vs Polyrepo: What the Blast Radius Tells You](https://upstreamapi.com/journal/monorepo-vs-polyrepo): Monorepo or polyrepo: 320 teams benchmarked, the blast radius math, and the 30% rule that high-performing platform teams actually use.
- [Action Items: The Part of Post-Mortems Nobody Gets Right](https://upstreamapi.com/journal/action-items-post-mortems-that-actually-close): Post-mortem action items fail not because teams skip the review. They fail because items lack named owners, live in docs nobody reads, and never land in sprint work where engineering actually happens.
- [What Are Feature Flags? A Field Guide for Platform Teams](https://upstreamapi.com/journal/what-are-feature-flags): Feature flags let you ship code to production without exposing it to users. Here is a precise, operational guide to how they work and where the failure modes actually live.
- [AI Technical Debt Is Wrecking Platform Reliability](https://upstreamapi.com/journal/ai-technical-debt-platform-reliability): AI tools now write 41% of production code. Technical debt grows 30-41% after adoption. How platform teams detect and fix AI technical debt.
- [AI Assisted Development: Closing the Rollout Safety Gap](https://upstreamapi.com/journal/ai-assisted-development-rollout-safety-gap): Platform teams shipping AI-generated code face failure modes standard error rate and latency gates were not designed to catch. Here is what to instrument instead.
- [AI Coding Productivity: What the SLO Budget Tells You](https://upstreamapi.com/journal/ai-coding-productivity-slo-budget): AI boosts coding output 33-98%. Incidents per PR are up 242%. Here is what the SLO budget measures when your team runs on Copilot or Cursor and deployment frequency climbs.
- [Cyclomatic Complexity: A Rollout Risk Signal, Not a Gate](https://upstreamapi.com/journal/cyclomatic-complexity-rollout-risk): Most teams treat cyclomatic complexity as a static CI gate. Here's why the complexity delta per diff predicts rollout risk far better than a flat threshold ever will.
- [8 AI Agent Examples Platform Teams Run in Production](https://upstreamapi.com/journal/ai-agent-examples): A field guide to AI agent examples that platform teams actually run in production: rollback, triage, diagnostic, and runbook agents, with where each one breaks.
- [Code Refactoring Techniques That Hold in Production](https://upstreamapi.com/journal/code-refactoring-techniques): Code refactoring techniques are not about clean code aesthetics. They are about reducing the surface you have to debug at 3am. Here is what actually works in continuous deployment environments.

## Comparisons

- [Datadog vs Grafana in 2026: An SRE's Honest Comparison](https://upstreamapi.com/compare/datadog-vs-grafana): Datadog's agent ships a working dashboard in minutes and pairs it with an AI incident agent. Grafana's free tier and open-source stack keep the bill predictable if you own Prometheus yourself.
- [Manus Alternatives in 2026: 4 Platforms Compared on Reviews](https://upstreamapi.com/compare/manus-alternatives): Four real Manus alternatives checked against G2 and Trustpilot data, pricing pages, and documented API access. Devin wins on evidence if the job you're replacing Manus for is code.
- [Manus AI Alternatives: 4 Platforms Worth Testing in 2026](https://upstreamapi.com/compare/manus-ai-alternatives): Manus is the reference for one-shot autonomous agents, but its credit pricing and thin review base send people looking elsewhere. Four real alternatives, compared on evidence.

## Reviews

- [Datadog Pricing in 2026: What You Actually Pay Per Host](https://upstreamapi.com/review/datadog-pricing): Datadog's list price is $15/host/month for Infrastructure Pro. We modeled real bills at 3 team sizes, cross-checked 884 G2 reviews, and compared the math to New Relic, Grafana Cloud, and Dynatrace.
- [Tabnine Review 2026: Is the Enterprise Pivot Worth $39/Mo?](https://upstreamapi.com/review/tabnine-review): An evidence-based Tabnine review: aggregated ratings from six platforms, verified pricing, real screenshots, and where it loses to Copilot and Cursor on complex code.
- [Skywork AI Review (2026): An SRE's Honest 18-Day Verdict](https://upstreamapi.com/review/skywork-ai-review): An 18-day test of Skywork AI's Documents, Slides, and Sheets agents on real postmortems and runbook decks, plus the pricing and compliance gaps to know before signing up.

## Landings

- [AI for Software Development: Ship Fast, Recover Faster](https://upstreamapi.com/lp/ai-for-software-development): AI for software development means more code, faster. It also means more incidents, per DORA's own 2025 data. upstreamapi auto-rolls back the ones that would have paged you.

## Tools

- [Cron Expression Generator: Build and Verify Schedules](https://upstreamapi.com/tools/cron-expression-generator): A free cron expression generator that builds or validates a standard 5-field schedule, then shows a plain-English description and the next five run times in UTC.
- [AI Unit Test Generator: Free Test Scaffold Builder](https://upstreamapi.com/tools/ai-unit-test-generator): A free AI unit test generator that turns a function name and parameters into an Arrange-Act-Assert test scaffold for Jest, Vitest, pytest, or Go, plus the edge cases worth testing.
- [AI Report Generator: Build Your Ops Report Outline](https://upstreamapi.com/tools/ai-report-generator): This free AI report generator builds a report outline and KPI list for API metrics, incidents, deployments, cost, or analytics data, tailored to your audience and reporting cadence.
