Import crystal structures, configure 21+ parameter panels, visualize orbitals and Brillouin zones, extract material properties, and collaborate with your team — all from a modern web interface that generates ready-to-run .fdf files.
From structure import to output analysis — a complete environment for preparing and understanding your DFT simulations.
21+ parameter panels covering every SIESTA block — edit and preview your .fdf in real time.
Interactive Three.js viewer with periodic boundary conditions, Wigner-Seitz cells, and orbital overlays.
Build supercells, slabs, defects, doped alloys, nanotubes, and heterostructures interactively — with symmetry detection and multi-format export.
Parse SCF convergence, DOS, PDOS, band structures, combined Band+DOS, and ANI trajectory playback.
Build multi-step DFT pipelines (relax → bands → DOS) on a visual canvas with batch mode and built-in templates.
Apply built-in or user-saved presets for quick parameter configuration. Import and export as JSON.
Automated parameter sweeps for mesh cutoff, k-points, and basis size. Export ZIP with submit scripts.
Browse the PseudoDojo catalog, auto-download PSMLs, and bundle pseudopotentials with workflows.
Real-time validation with a health score, categorized warnings, and one-click fixes for common issues.
Upload CIF, FDF, or XV files, search the OPTIMADE federated database, or build from scratch with the interactive structure builder.
Sign in with Google, GitHub, or ORCID. Save calculations to the cloud and access them anywhere.
Organize calculations and analyses into projects with folders, drag-drop sorting, and team collaboration.
Full interface in English, Spanish, Catalan, and Persian, with native right-to-left support for Persian. Switch languages instantly.
Showcase
Upload CIF, FDF, or XV files, search OPTIMADE, or build custom structures — supercells, slabs, defects, and alloys — using the interactive builder.
Tune your simulation with 21+ parameter panels — from basis sets and k-point grids to MD settings — all with live .fdf preview.
Parse SIESTA output files for convergence, band structures, DOS, material properties, and trajectory playback — then organize results in collaborative projects.
Standard .fdf files compatible with any SIESTA installation. No vendor lock-in.
Data stays in your browser until you explicitly save. No tracking, no telemetry.
Built on OPTIMADE, CIF, PSML, and XV — the formats your community already uses.
All core features are free for researchers. No credit card, no trial limits.
Join researchers worldwide using SiestaStudio to prepare, visualize, and analyze SIESTA calculations — all from the browser.
