ggsql is an alpha-stage visualization tool from Posit (makers of RStudio) that brings the grammar of graphics directly into SQL. Instead of exporting to R or Python for plotting, analysts can write VISUALIZE statements alongside their SQL queries and get publication-quality charts as output. The syntax is designed to be spoken aloud: "VISUALIZE bill_len AS x, bill_dep AS y FROM ggsql:penguins DRAW point" is a readable declaration, not a configuration object. The project comes from a credible lineage: built by Thomas Lin Pedersen, Teun Van den Brand, George Stagg, and Hadley Wickham — the team behind ggplot2, the most-downloaded R package of all time. Hadley's involvement signals this isn't an experiment from a junior team; it's a considered effort to bring the ggplot philosophy to SQL-native workflows. Outputs render as self-contained HTML with inline SVG charts (no JavaScript runtime required) and PDF exports, usable in Quarto, Jupyter, Positron, and VS Code. With 281 points on Hacker News on launch day, the reception reflects genuine excitement from the data analytics community. The SQL-native approach matters because it meets analysts where they already work — rather than asking them to learn yet another visualization library. Whether ggsql becomes a standard layer in the modern data stack depends on how the alpha stabilizes, but the concept and team behind it are both strong.

AI analytics agent for D2C ad performance — connects 15+ channels, diagnoses drops

Predflow AI is an autonomous analytics agent built for D2C brands running paid advertising across multiple channels. It connects Meta, Google, Amazon, Shopify, and 15+ additional data sources into a unified dashboard, then actively monitors for performance changes — diagnosing root causes of spend efficiency drops, identifying creative fatigue, and surfacing multi-touch attribution insights through a natural language interface. Unlike traditional dashboards that show what happened, Predflow surfaces why it happened and what to do. When ROAS drops on Meta, it cross-references creative age, audience saturation, landing page performance, and competitor activity patterns to construct a diagnosis rather than just reporting the metric. The natural language interface means media buyers can ask questions like "why did my Friday CPAs spike" instead of navigating manual filter views. The platform launched on Product Hunt today, reaching #5 with 145 upvotes. It targets growth teams at D2C brands spending $50K–$2M/month on paid acquisition — teams large enough to have complex multi-channel operations but not large enough for enterprise analytics contracts. Multi-touch attribution is the deepest technical claim: most D2C attribution tools use last-click or simple data-driven models; Predflow claims to handle cross-channel attribution with conversion path analysis.
Reviewer scorecard
“The Hadley Wickham signal alone is worth paying attention to. Grammar of graphics in SQL is the obvious next step for data stack tools, and having the person who invented ggplot2 leading the effort means the underlying design will be coherent, not bolted-on. Even in alpha, this is worth integrating into a Quarto workflow.”
“Natural language querying over unified ad performance data is something every D2C growth team has wanted for years. The diagnostic layer — going beyond 'ROAS dropped' to 'ROAS dropped because creative #4 is fatigued and your landing page bounce rate increased' — is genuinely valuable if the signal quality is there. 15+ source connectors at launch is a credible integration bet.”
“Alpha software from an academic-leaning team with a history of slow iteration. ggplot2 is phenomenal but it took years to stabilize. The SQL grammar also risks becoming a DSL-within-a-DSL mess as edge cases pile up. Wait for the beta and see if the syntax holds up against real production query patterns.”
“Triple Whale, Northbeam, and Rockerbox are well-established in this exact space with massive data moats and proven attribution models. 'AI agent for ad analytics' is a crowded pitch. Without seeing actual attribution methodology or a free tier to evaluate accuracy, it's hard to recommend over incumbents that media buyers already know.”
“The convergence of AI-generated SQL and visualization is inevitable. When LLMs can write VISUALIZE statements as naturally as SELECT statements, the distinction between 'data pipeline' and 'dashboard' disappears. ggsql is building the primitive that makes that future possible.”
“The agentic shift in analytics — from dashboards you query to agents that monitor and diagnose — is real and happening fast. Predflow is betting that the interface paradigm for marketing data is changing, not just the analysis. If the attribution data is solid, the agent-first approach gives it a structural advantage as the category evolves.”
“Self-contained HTML output with inline SVG is the right format for sharing data stories — no dependencies, no runtime, just open the file. For newsletters, reports, and presentations, being able to generate a chart directly from a query without a Python script in between is a workflow improvement I'd use daily.”
“For creators managing their own paid promotion or working as consultants, having an AI that can answer 'what's actually working and why' across all channels in plain language is a real time saver. The creative fatigue detection is the feature I'd use most — knowing when to refresh vs. kill an ad is always a judgment call I'd love data support on.”
