In-Depth Analysis

dif.sh

Feature flags and A/B testing versioned in your git repo

Starts at Free

Strengths

+Simplifies experiment management by keeping everything in the repo alongside code.
+No separate service needed for basic use; free CLI and SDK work offline.
+Built-in conflict detection prevents invalid experiment combinations before they reach production.

Weaknesses

-Requires CLI setup and familiarity with markdown frontmatter; less visual than GUI-based tools.
-Advanced metrics and team dashboards require the paid cloud tier.
-Primarily designed for developer teams; non-technical stakeholders may find the file-based approach less accessible.

Key features

File-based experiments: each flag or test is a single .md file with frontmatter for id, status, variants, metrics, and audience rules.Git-native workflow: experiments are versioned, reviewed in PRs, and git serves as the audit log.Conflict detection at build: dif build resolves exclusion graphs and fails if two live tests would collide on the same user.Exclusion groups: one frontmatter line prevents users from being bucketed into multiple overlapping experiments.Audience targeting: declare attributes in config.yaml, values arrive at runtime from user context; no customer data is committed.Guardrails: define secondary metrics (e.g., refund_rate) that compile into the client to monitor side effects.

VWO

Experimentation and conversion optimization

Starts at $299/mo
