SALTO
The challenge the product solves
During election season, looking up candidates on the official portal is slow and not built for mobile, and most of what circulates on social media has no source. On counting night, interest spikes all at once and many sites simply go down.
Vote Certo was born to be the impartial shortcut: TSE data exactly as the TSE publishes it, organized so voters find what they need in seconds, build their cheat sheet, and follow the official result with no ads, no sign-up, and no downtime at peak.
Product metrics and highlights
Integrations and real-time updates
Candidacies straight from TSE open data
The database is loaded from the official 2026 candidate files and refreshed periodically during registration: ballot name, number, party, candidacy status, declared assets, and photo. Nothing is edited or filtered, and every load is logged with date and time on the app's own data page.
Live counting as the polls close
When counting starts, Vote Certo reads the official TSE results and consolidates them by office and by state. The results page updates on its own as polling sections are counted, showing the share of sections counted, valid votes, blank and null votes, and abstention, all the way to 100%.
Edge infrastructure, ready for the peak
A lightweight front end served at the network edge, a custom API on Cloudflare Workers, a D1 database, and files on R2. Election night traffic is absorbed without server queues and at minimal operating cost.
The Salto Engineering Competitive Edge
Vote Certo shows Salto Solutions' ability to turn raw public data into a high-scale product that is reliable and simple to use:
- Neutral by design: names and numbers appear as the TSE publishes them, in alphabetical order, with no ranking; percentages only exist on the counting page, with official numbers.
- Real privacy: no cheat sheet is ever tied to a person; choices stay on the user's own device.
- Scale at low cost: serverless edge architecture that handles massive traffic spikes without an expensive server cluster behind it.
