About Go Silph
A Pokemon GO database built by one person, from the game's own data files, with no paywalls and no accounts.
What Go Silph is
Go Silph is a Pokemon GO reference built for players who want to know what to power up before they spend the stardust: raid counters ranked by DPS and total damage, PvP rankings for every league, a full Pokedex, the live event calendar and the current egg pool.
Data that follows the game
Stats, movesets and rankings are recalculated when Niantic ships a game update, so a rebalanced move shows up here without anyone having to remember to edit a page.
Tools, not just tables
DPS and TDO raid counters, PvP meta rankings and search-string helpers — the things you actually open mid-raid or mid-cleanup, designed to be readable on a phone.
Free and account-free
No login, no paywall, no data collection beyond the basics described in the privacy policy. Ads pay for the servers.
How the data is produced
Where each number on the site comes from
Source data
Every Pokemon stat, move and game mechanic comes from Niantic's GAME_MASTER file, decoded and maintained by the PokeMiners community — the same file the game client reads.
Raid rankings (PvE)
Counter rankings are calculated from DPS (damage per second) and TDO (total damage output) against each boss's typing, using the current move data. The approach follows the method shared by DialgaDex, adapted for this site.
PvP rankings
League rankings come from win-rate simulations across the meta, evaluating each Pokemon head to head at its league CP cap. The framework builds on the work of PvPoke.
Update cycle
The pipeline watches for game updates and reprocesses rankings, counters and competitive data automatically. Event, raid and egg data is refreshed daily.
Editorial standards
There are three kinds of content on Go Silph, and they are made in different ways:
Computed
Stats, CP tables, raid counters, lobby-size estimates and league rankings are calculated by the site's own code from the game files, with the methods described above. Nobody types those numbers in, which is why they change on their own after a game update.
Written by hand
The guides, the per-type attacker write-ups and the notes on individual Pokemon are written by the editor and checked against Niantic's official announcements and the in-game data. Each guide shows the date it was last verified and what changed since.
Drafted with AI, from our data
The weekly briefing on the home page, the league meta notes and the short event and raid boss summaries are drafted with the help of a language model that is only given the site's own data for that week. It works under written rules — no invented spawns, bonuses or mechanics — and its output is validated against the game data before it is published. Summaries that fail the check are not shown.
