This is really nice, specially the pdf report generation.

I feel very moronic making a dashboard for any products now. Enterprise customers prefer you integrate into their ERPs anyway.

I think we lost the plot as an industry, I've always advocated for having a read only database connection to be available for your customers to make their own visualisations. This should've been the standard 10 years ago and it's case is only stronger in this age of LLMs.

We get so involved with our products we forget that our customers are humans too. Nobody wants another account to manage or remember. Analytics and alerts should be push based, configurable reports should get auto generated and sent to your inbox, alerts should be pushed via notifications or emails and customers should have an option to build their own dashboard with something like this.

Sane defaults make sense but location matters just as much.

Roughly three decades ago, that *was* the norm. One of the more popular tools for achieving that was Crystal Reports[1].

In the late 90s, it was almost routine for software vendors to bundle Crystal Reports with their software (very similar to how the MSSQL installer gets invoked by products), then configure an ODBC data source which connected to the appropriate database.

In my opinion, the primary stumbling block of this approach was the lack of a shared SQL query repository. So if you weren’t intimately aware with the data model you wanted to work with, you’d lose hours trying to figure it out on your own or rely on your colleagues sharing it via sneakernet or email.

Crystal Reports has since been acquired by SAP, and I haven’t touched it since the early ‘00s so I don’t know what it looks or functions like today.

100% agreed regarding shipping a read-replica, for any sufficiently complex enterprise app (ERP, CRM, accounting, etc.).

Customers need it to build custom reports, archive data into a warehouse, drive downstream systems (notifications, audits, compliance), and answer edge-case questions you didn’t anticipate.

Because of that, I generally prefer these patterns over a half-baked built-in analytics UI or an opinionated REST API:

Provide a read replica or CDC stream. Let sophisticated customers handle authz, modelling, and queries themselves. This gets harder with multi-tenant DBs.

Optionally offer a hosted Data API, using something like -- PostgREST / Hasura / Microsoft DAB. You handle permissions and safety, but stay largely un-opinionated about access patterns.

Any built-in metrics or analytics layer will always miss edge cases.

With AI agents becoming first-class consumers of enterprise data, direct read access is going to be non-negotiable.

Also, I predict the days of charging customers to access their own goddamn data, behind rate-limited + metered REST APIs are behind us.

Customers don’t want to learn your schema or deal with your clever optimizations either. If you expose a DB make sure you abstract everything away in a view and treat it like a versioned API.

I get your point, but generally with most enterprise-scale apps you really don’t want your transactional DB doubling as your data warehouse. The “push-based” operation should be limited to moving data from your tx environment to your analytical one.

Of course, if the “analytics” are limited to simple static reports, then a data warehouse is overkill.

I wanted to love DuckDB but it was so crashy I had to give up.
I had this too until I lowered it's memory limit. In ~/.duckdbrc `set max_memory='1GB';` or even less
interesting i am trying to build one too but rejected duckdb because of large size, i guess i will have to give in and use it at some point of time.
In what extent this is a metabase alternative? I'm a heavy Metabase user and there's nothing to compare really in this product.
We've (https://www.definite.app/) replaced quite a few metabase accounts now and we have a built-in lakehouse using duckdb + ducklake, so I feel comfortable calling us a "duckdb-based metabase alternative".

When I see the title here, I think "BI with an embedded database", which is what we're building at Definite. A lot of people want dashboards / AI analysis without buying Snowflake, Fivetran, BI and stitching them all together.

Metabase works great with DuckDB as well, thanks to metabase_duckdb_driver by MotherDuck.
As someone who used duckdb but not shaper, what is shaper used for? The readme is scarce on details.
This is so cool and also MPL licensed! Thanks!
my company integrated tale shape as our customer-facing metabase dashboard alternative. absolutely love its simplicity!
Thanks for the cool tool! I think it's worth mentioning SQLPage, which is another tool in similar vein, to generate UI from SQL. From my POV:

- SQLPage: more on UI building; doesn't use DuckDB

- Shaper: more on analytics/dashboard focused with PDF generation and stuff; uses DuckDB

Nice work! I met Jorin a couple years ago at a tech meetup and this was just an idea at the time. So cool to see the consistent progress and updates and to see this come across HN.
Is there anyway to run the query -> report generation standalone in process? Like maybe just outputting the html (or using the React components in a project).

I was looking to add similar report generation to a vscode-extension I've been building[0]
